Look out for these pretty little mushrooms in damp deciduous broadleaf woodlands. The bluing mycena is very similar to Leas mycena except that, as the name implies, it is blue when young, not orange. The color fades to bright orange, then paler and more yellowish. First described in 1845 and originally named Agaricus leaiana. The gills are adnexed in attachment (gills narrowly attached/tapering toward stem so that their attachment is almost free), crowded together, and yellowish in color, with the color deepening to bright orange-red at the edges. adonis ). A rather strange and relatively rare species shown in F is the bluing Mycena, M. subcaerulea. Scutellinia setosa/erinaceous - Orange Eyelash Cup. This seems like a contradiction, since the spore print is white. The pigment responsible for the orange color in this species has antibiotic properties. Orange Mycena. It is quite variable in color (brown to pale), size, and shape, which makes it somewhat difficult to reliably identify in the field. The species is regarded as nonpoisonous. At that time any gilled mushroom was placed in the genus Agaricus. Berkeley wanted to honor Lea for his contribution. ConservationDescriptionHabitatBiologyDistributionTaxonomy. Remember that mushrooms are 90-95% water, so if there's no water there are no mushrooms, but Mycena leaiana seems to be a fantastic scavenger of water through its mycelium from wood. Miles Joseph Berkeley in the London Journal of Botany, vol. (1774)Agaricus miniatus Batsch (1783)Hemimycena acicula (Schaeff.) Jafnea semitosta. So what's with the weird specific epithet, leaiana?? Mycena leaiana, commonly known as the orange mycena or Lea's mycena, is a North American species of saprobic fungi in the genus Mycena, family Tricholomataceae. Singer (1951). Aleuria aurantia - Orange Peel Fungus. Mycena leaiana, commonly known as the orange mycena or Lea's mycena, is a species of saprobic fungi in the genus Mycena, family Mycenaceae. will only copy the licensed content. It's bright orange, with bright orange marginate gills (more on that later), and thus often stands out from a long distance. However, if it's been rainy, the orange color in the cap can actually wash out and fade to a pale tannish orange. Hollow, tough, and orange to orange yellow, but paler near the top. australis is a variety of Mycena leaiana found in Australia[1] and New Zealand. Avid fan, ever-learning and these little guys are popping up on wooded logs a few weeks after morels here. Browse 374 mycena mushrooms photos and images available, or start a new search to explore more photos and images. The fruit bodies, or mushrooms, of the fungus grow on dead twigs and other woody debris of forest floors, especially along streams and other wet places. (Thanks to Richard Aaron of Toronto for this information.) Characterized by their bright orange caps and stalks and reddish-orange gill edges, they usually grow in dense clusters on deciduous logs. Synonyms of Mycena acicula include Agaricus aciculaSchaeff.,Agaricus miniatus Batsch, Hemimycena acicula(Schaeff.) If you are one of the If you have anything to add, or if you have corrections, comments, or recommendations for future FotM's (or maybe you'd like to be co-author of a FotM? 0.5 to 1.8cm across; conical, becoming bell shaped; smooth with marginal striations; reddish when very young but soon becoming mid to dark orange and often a lighter shade of orange or yellow towards the rim. A small bright red striking species is M. strobilinoides (D). Characterized by their bright orange caps and stalks and reddish-orange gill edges, they usually grow in dense clusters on deciduous logs. You can find them around creeks, parks and forests. A paler pink/purple species is M. pura (E). Omphalotus olearius, [2] commonly known as the jack-o'-lantern mushroom, is a poisonous orange gilled mushroom that to an untrained eye appears similar to some chanterelles. The Rev. They are characterized by a white spore print, a small conical or bell-shaped cap, and a thin fragile stem. These wild mushrooms first appear in Southern Ohio and gradually spread northwards. Mycena haematopus Glow Both the mycelia and the fruit bodies of M. haematopus (both young and mature specimens) are reported to be bioluminescent. . Not only will get you a free field guide but you will get exclusive access to ground breaking studies, and discounts. Back by popular demand, Pat O'Reilly's best-selling 450-page hardback book is available now. It is found from June through September in woodlands, growing on the dead wood of deciduous trees. A relatively common, although not brightly colored species is M. galericulata (C), with its dark, fading stipe. Orange mycena Mycena leaiana ''Mycena leaiana'', commonly known as the orange mycena or Lea's mycena, is a species of saprobic fungi in the genus ''Mycena'', family Mycenaceae. Mycena luteopallens, A, is a paler, smaller (2-3 mm cap) orange mushroom that grows on the hulls of hickory nuts, walnuts and butternuts-- although you might have to dig down in the soil to find the substrate. M.strobilinoides, a North American and European species, looks similar with its orange cap, but may be distinguished microscopically by the cheilocystidia which are densely covered by excrescences;[7] it also has a larger cap, up to 2cm (0.8in). German mycologist Jacob Christian Schaeffer described the Orange Bonnet in 1762, giving it the binomial scientific name Agaricus acicula. Both species tend to occur as singletons . Mycena is a large genus of small saprotrophic mushrooms that are rarely more than a few centimeters in width. In most cases, a careful look at the overall color (most are less orange) and at where and when the mushroom is growing will be enough to make clear which are not really Leas mycena. The specific epithet acicula means 'with bristles, pins or needles'. [5] The diameter of the stipe is more or less equal throughout its length, although it may be slightly enlarged at the base. When handled, the orange pigment will stain the skin. An occasional find in both deciduous hardwood forests and in conifer plantations, the Scarlet Bonnet differs in having a reddish-orange or bright pink cap, and its stem is usually white (but red in var. [3][4], The hygrophanous cap is 1 to 4 centimetres (0.39 to 1.57in) in diameter, and initially rounded or bell-shaped but becoming expanded and convex with age, often with a depression in the center. It is notable for its bioluminescent properties. [8] In recent years, mycologists have conducted research examining the development of bioluminescence within fungi, investigating the origin of the genes coding for luciferase enzymes that cause these fantastic visible traits. The pigment responsible for the orange color in this species has antibiotic properties. The orange color comes off on your hands when you touch it, and I The trama is soft, watery, and white. That being said, there seems to be nothing to recommend it for the table anyway, since it's very small and has a rather rubbery texture if you try to cut it. Cystidia on the edge of the gill are scientifically called "cheilocystidia" (literally, "lip cystidia"). The orange mycena has no distinctive taste, and a slightly mealy odor. M.aurantiidisca can be distinguished by the reddish-orange cap which tends to become paler at the margin. Leas mycena is not known to be edible, therefore any medicinal or nutritional benefits arent known, either. The edibility of this fungus is unknown, but is not known to be poisonous. with a hand lens, you can see that the orange color is mostly restricted to the edge of the gills. [In the 1880's, Saccardo moved the species to Mycena when the diverse and artificial genus Agaricus was being split into so many of the genera we know today.] Mycena leaiana, commonly known as the orange mycena or Lea's mycena, is a North American species of saprobic fungi in the genus Mycena, family Tricholomataceae. Characterized by their bright orange caps and stalks and reddish-orange gill edges, they usually grow in dense clusters on deciduous logs. Microscopic Features: Spores 7-10 x 5-6 ; elliptical; weakly to moderately amyloid, or sometimes nearly inamyloid when mature and separated from basidia. A very common species, Mycena haematopus, the blood-foot mushroom, exudes a blood-colored latex when the stipe is cut.

They have small orange-red caps, up to 1cm (0.4in) in diameter, held by slender yellowish stems up to 6cm (2.4in) long. [10] It is better distinguished microscopically: it has smaller spores, shorter and narrower basidia, and distinctive cystidia.[10]. Schalkwijk-Barendsen, Helene M. E. (1991). The surface is densely white-pruinose initially, but soon becomes naked with a subsequent color shift to orange-yellow or lemon yellow. editors of this guide it should copy everything, but if you're not, it The name Mycena comes from the Ancient Greek mykes, meaning "fungus". The hyphae of the cortical layer of the stem are smooth and not embedded in gelatinous matter, and in European collections the basidia are two-spored and do not have clamps. The orange mycena, photographed in West Virginia, USA. An even closer look with a microscope reveals that the orange pigment is mostly restricted to cystidia, sterile cells at the edge of the gill. [10], The cap is initially convex, but as it matures, it expands to a bell-shape, typically reaching 0.3 to 1cm (0.1 to 0.4in) in diameter. would imagine it would do the same in your mouth. [5] The color is a bright orange that fades as the mushroom matures. Learn more about fungi! On the top of the fruiting bodies you can see the characteristic orange color, with growth in caespitose clusters (meaning that many mushrooms emanate from a single point on the log). However, M. leaiana had been found primarily in the east of the United States (and specifically not on the Pacific coast at all) upon the discovery of specimens in Australia. When squeezed, it exudes a watery orange juice. Dictionary of the Fungi; Paul M. Kirk, Paul F. Cannon, David W. Minter and J. They are nonamyloid, meaning they do not take up iodine when stained with Melzer's reagent. An even closer look with a microscope reveals that the orange pigment is mostly restricted to cystidia, sterile cells at the edge of the gill. The orange Mycena is a small mushroom species that grow in clusters. Berkeley also wrote "I have myself corresponded on the subject with their discoverer and can bear witness to his great kindness and zeal; and I have no doubt that mycology will be further enriched by his labours."

Characterized by their bright orange caps and stalks and reddish-orange gill edges, they usually grow in dense clusters on deciduous logs. Pleurocystidia scattered to abundant; to about 50 x 15 ; fusoid-ventricose to mucronate. Clathrus ruber: The Ultimate Mushroom Guide. Last Updated: 8/15/2022 Miles Joseph Berkeley in the London Journal of Botany, vol. Berkeley wanted to honor Lea for his contribution. Below and to the left you can see what these cystidia look like microscopically. A very common species, Mycena haematopus, the blood-foot mushroom, exudes a blood-colored latex when the stipe is cut. Learn more about fungi! Take some time to look at all the beautiful little fungi all around you. A. Stalpers; CABI, 2008. However, the luminescence is quite weak, and not visible to the dark-adapted eye; in one study, light emission was detectable only after 20 hours of exposure to X-ray film. Oliveira et al. and accompanied in many instances by very copious and valuable notes." The gills are adnexed in attachment (gills narrowly attached/tapering toward stem so that their attachment is almost free), crowded together, and yellowish in color, with the color deepening to bright orange-red at the edges.

This beautiful little Mycena decomposes the deadwood of hardwoods from the Great Plains eastward. Mycena leaiana (Berk.) When in doubt, check the gills and the base of the stem; enoki gills are the same color all over, including the edges, and when wild-grown enokis have black stem bases. It's native to North America, New Zealand, and Australia and is found growing in woodlands. Even though the mushrooms themselves are quite small at maturity, usually less than an inch (3 cm) in diameter, they can be very prolific fruiters, so there is often a large amount of it to be seen. It is pretty, a bright little patch of color, and it could conceivably be confused with at least one edible species. Sacc. It is smooth except rough to the touch just near the top when young. The hymenophore is . This is yet another example of the contribution of an amateur to the science of Mycology. And since the bluing mycena is at least rumored to be halucinogenic (in mentioning the rumor this article makes no comment on whether the rumor is true or whether the mushroom is safe to eat; not all hallucinogens are), meaning somebody might eat some. Stem: 3-7 cm long; 2-4 mm thick; equal; hollow; smooth; fairly tough and cartilagenous; sticky when wet; the base covered with orange to whitish powder or dust; orange or orangish yellow, but paler near the apex; sometimes exuding an orange juice when squeezed. The proper way to make an epithet honoring someone is to add -iana to the name; thus we end up with leaiana. These species are divided among 16 lineages, leading to evolutionary uncertainty in whether the luminescence developed once and was lost among many species, or evolved in parallel by several species. About the same small size orange-red species include M. acicula and M. adonis. Some species, like Mycena haematopus, exude a latex when the stem is broken, and many species have a chlorine or radish-like odour. editors of this guide it should copy everything, but if you're not, it Note the blue color of the base of the stem and of the very young caps. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); The statements made on healing-mushrooms.net have NOT been evaluated by the FDA. Sacc. Really pretty wild mushrooms that grow in the fall/autumn months here in the ozark mountains! A paler pink/purple species is M. pura (E). However, that species has a dark black stem, at least at the base, and the gills are not marginate. Alexander Smith described this as Mycena leaiana var. The latest second edition was republished with a sparkling new cover design in September 2022 by Coch-y-Bonddu Books. However, that species has a dark black stem, at least at the base, and the gills are not marginate. Mycena acicula: The Ultimate Mushroom Guide. The hymenium is most often either lamellate or poroid, dependent upon the species. The gills are closely spaced or crowded. However if you look away from the gill edge toward the basidia (basidiospore producing structures), you can often find some wayward orange cystidia borne singly among the basidia. Another species that has marginate gills is M. rutilaniformis (B). Orange Mycena Mycena leaiana Violet-toothed Polypore Trichaptum biforme Crown Coral Clavicorona pyxidata Artist's Conch Ganoderma applanatum AUTUMN White Elfin Saddle Helvella crispa Chicken of the Woods Laetiporum sulphureus Hen of the Woods Grifola frondosa Turkey-tail Trametes versicolor Violet-toothed Polypore Trichaptum biformis [12][13], The spores are roughly spindle-shaped (i.e., tapering at each end), with dimensions of 911 by 3.54.5m. Most are grey or brown, but a few species have brighter colours. Orange Mycena (Mycena Leaiana) Mycena leaiana is a species of mushrooms with origins in North America, but there is a related variety ( Mycena leaiana var. The margin is curved inward. will only copy the licensed content. Mycena adonis Mushroom Identification. Flammulina velutipes also tends to fruit when it's rather cold, such as early spring and late fall. The color is the same as the cap, but it is often paler near the top. Originally named Agaricus leajanus by the English biologist Miles Joseph Berkeley in 1845, Pier Andrea Saccardo was later (1891) to move it to the genus Mycena when the large genus Agaricus was divided. A variety of the species, Mycena leaiana var. It seems odd to us now that Cincinnati would be considered an exotic location, but remember that North America was just being colonized by Europeans. The cap sometimes has a small abrupt umbo (a central bump), and the cap margin is pressed closely against the stem when young, often flaring or curving slightly inward. This page and other pages are Copyright 2005 by Thomas J. Volk, University of Wisconsin-La Crosse. [4] If handled, the yellow pigment will rub off and stain the skin.[6]. The species' stalks are very slender, being almost filament-like. A small bright red striking species is M. strobilinoides (D). Beautiful Wild Fall Autumn Mushroom Hunting Orange Mycena leaiana. Harttig U, Anke T, Scherer A, Steglich W. (1990). A rather strange and relatively rare species shown in F is the bluing Mycena, M. subcaerulea. Clitocybe rivulosa: The Ultimate Mushroom Guide. Peziza repanda - Palamino Cup. and accompanied in many instances by very copious and valuable notes." [13] Mycena specialist Alexander H. Smith further noted of M.acicula that it could readily be mistaken for a Hygrophorus. If you have anything to add, or if you have corrections, comments, or recommendations for future FotM's (or maybe you'd like to be co-author of a FotM? [8] The variant Mycena leaiana var. Characterized by their bright orange caps and stalks and reddish-orange gill edges, they usually grow in dense clusters on deciduous logs. pallida, meaning the pallid (light colored) form of Mycena leaiana, but these are probably just washed out mushrooms. Since Leas mycena is not used medicinally, it has no dosage. Some species are edible, while others contain toxins, but the edibility of most is not known, as they are likely too small to be useful in cooking. Compare these to the "pleurocystidia" ("side cystidia") found on (you guessed it) the sides of the gills of Pluteus cervinus. If you look on the underside of the mushroom, you can see that the gills are orange. He died not long afterwards, and this orange mushrooms name is his memorial.

Its not that no other mushroom has this featureeven some look-alikes have it. Fascinated by Fungi. 1. Mushrooms are the fleshy, spore-bearing fruit of various fungi. [5] The spore print is white. Note the blue color of the base of the stem and of the very young caps. Mycena leaiana, commonly known as the orange mycena or Lea's mycena, is a species of saprobic fungi in the genus Mycena, family Mycenaceae. Because this is not a species people eat, mistaking another species for Leas mycena is not a disaster in most cases. Taxonomy is complex, as most sections are not truly homogeneous, and the keys fail for some species, especially those that satisfy some criteria for only part of their life cycle. One advantage of bioluminescence may lie in its potential to attract insects that can disperse the mushroom's spores. Most are grey or brown, but a few species have brighter colours. [3], Over 58 species are known to be bioluminescent,[5][6] creating a glow known as foxfire. The cap measures about 2.8 inches in length. Young mushrooms have a convex shape and transparent color, stripes are visible on their surface, have a gray-brown, gray-brown, pale, or grayish-fawn color. There are a number of other Mycena species that are relatively easy to identify. [5] Spores are elliptical in shape, smooth, amyloid, and have dimensions of 71056 m. In Mycena leaiana the edges are orange, like the cap and stem, but close inspection of the faces reveals them to be creamy or very pale orange. Come find out the supplement industry's dirty secret. The edibility of this fungus is unknown, but is not known to be poisonous. Because of their orange color and caespitose habit, you might confuse the orange Mycena with Flammulina velutipes, also known as the winter mushroom, velvet stem, velvet foot, enoki, or enokitake. The surface of the cap is sticky, especially in moist weather, and smooth, while the margin often has striations. This is yet another example of the contribution of an amateur to the science of Mycology. Go to Tom Volk's Fungi Home Page --TomVolkFungi.net Mycena leaiana, commonly known as the orange mycena or Lea's mycena, is a North American species of saprobic fungi in the genus Mycena, family Tricholomataceae. pallida, meaning the pallid (light colored) form of Mycena leaiana, but these are probably just washed out mushrooms. [9], Mycena is a rich genus, considered one of the most abundant genera of mushrooms within the Agaricales and with species distributed across the world.[3]. ; yellow; smooth or slightly powdery, particularly towards the apex; no ring. A paler pink/purple species is M. pura (E). 1. However, if it's been rainy, the orange color in the cap can actually wash out and fade to a pale tannish orange. Orange mycena is a small, delicate looking mushroom. [9], Mycena texensis A.H. Sm. Mycena pura contains the mycotoxin muscarine, but the medical significance of this is unknown. Fascinated by Fungi, 2nd Edition, Pat O'Reilly 2016, reprinted by Coch-y-bonddu Books in 2022. 4 (1845). Leainafulvene has weak antibacterial activity against Acinetobacter calcoaceticus, and has pronounced cytotoxic activity towards tumor cells. Leratiomyces ceres: The Ultimate Mushroom Guide. Another species that has marginate gills is M. rutilaniformis (B). Current Biology, 25(7). It was another German, Paul Kummer, who in 1871 transferred this species to its present genus, thus establishing its currently-accepted scientific name Mycena acicula. So far, the literature suggests 3 separate origins of bioluminescence within Agaricales, occurring within the families Omphalotaceae, Physalacriaceae, and Mycenaceae. It is tough, cartilaginous, hollow, and sticky when wet. Giovanni Robich, (2003). Usually fruits in clumps, more rarely singly. First named Agaricus acicula by the German scientist Jacob Christian Schffer in 1774,[2] the species was also referred to as Agaricus miniatus by another German, naturalist August Batsch. with a hand lens, you can see that the orange color is mostly restricted to the edge of the gills. (Thanks to Lorelei Norvell and Scott Redhead for this information, published in Mushroom the Journal of Wild Mushrooming 17(4):27-29, 1999.) The trama is soft, watery, and white. The stipe is typically 3 to 7 centimetres (1.2 to 2.8 in) long by 24mm thick. Older caps are sometimes almost white. Mycena is a large genus of small saprotrophic mushrooms that are rarely more than a few centimeters in width. Adnexed to almost free; white or pale yellowish-orange with paler gill edges. The gills are moderately broad, pale orange to whitish, often yellowish at the base and whitish along the edges. . [5]Spores are elliptical in shape, smooth, amyloid, and have dimensions of 71056 m. There are a lot of mushrooms that look at least vaguely like Leas mycena, but a close look will usually make the difference clear. However, if it's been rainy, the orange color in the cap can actually wash out and fade to a pale tannish orange. Occasionally you may come across slightly papillate (narrowly umbonate) specimens. (Thanks to Lorelei Norvell and Scott Redhead for this information, published in Mushroom the Journal of Wild Mushrooming 17(4):27-29, 1999.) The company is called Noomadic Herbals, my favorite supplement they make is called "Mushroom Total". Grows in dense clusters on deciduous wood. Take some time to look at all the beautiful little fungi all around you. If you are one of the australis can be found in Australia[1] and New Zealand. Mycena Acicula. This striking little bonnet mushroom occurs throughout mainland Europe and many other parts of the world including North America. Even in dry weather you can often find it because it uses the water found very deep in the log to produce its fruiting bodies. A relatively common, although not brightly colored species is M. galericulata (C), with its dark, fading stipe. Berkeley himself tells us in describing several new species: "This and the greater part of the following species, are described from a rich collection of fungi consisting of above 280 species, from the neighbourhood of Cincinnati, kindly sent to Sir W. J. Hooker by T. G. Lea, Esq. The edibility of this fungus is unknown, but is not known to be poisonous. Characterized by their bright orange caps and stalks and reddish-orange gill edges, they usually grow in dense clusters on deciduous logs. They have orange caps that fade towards the . This species is reported to actually contain the hallucinogen psilocybin, although it's not at all related to Psilocybe. However if you look away from the gill edge toward the basidia (basidiospore producing structures), you can often find some wayward orange cystidia borne singly among the basidia.
