Cyptotrama asprata (alternatively spelled aspratum), commonly known as the golden-scruffy collybia [2] or spiny woodknight [3] is a saprobic species of mushroom in the family Physalacriaceae. Widely distributed in tropical regions of the world, it is characterized by the bright orange to yellow cap that in young specimens is covered with tufts of fibrils resembling small spikes. This fungus has had a varied taxonomical history, having been placed in fourteen genera before finally settling in Cyptotrama . This species is differentiated from several other similar members of genus Cyptotrama by variations in cap color, and spore size and shape.
This species was first described from Ceylon by English naturalist Miles Joseph Berkeley in 1847; [4] soon after (1852), specimens were collected from South Carolina USA. [5] Later, the fungus was described under a variety of names: Lentinus chrysopeplus from Cuba; [6] Agaricus sabriusculus and Agaricus lacunosa from New York; [7] [8] Collybia lacunosa from Michigan; [9] and Omphalia scabriuscula in Connecticut. [10] As Canadian mycologists Redhead and Ginns explain in a 1980 article on the species, since its original 1847 description, C. asprata has been given 28 names, and placed in 14 different genera. [11]
The cap is 0.6 to 2.7 cm (0.24 to 1.06 in) in diameter, convex to cushion-shaped. The cap surface is dry, and younger specimens are covered with characteristic spikes; as the spikes break up with age, they tend to look more hairy or woolly. Older specimens typically have the surface features worn off. The cap margin tends to be rolled inwards when young, gradually becoming straight with maturity. The color of the cap is bright or pale yellow, increasing in intensity towards the center of the cap. C. asprata has a web-like ring that soon disappears.
The gills, pale yellow to white in color, are distantly spaced and have an adnate (squarely attached) or short decurrent (running down the length) attachment to the stem; they feel greasy when dried and crushed. The stem is 1 to 6.7 centimetres (0.4 to 2.6 in) long by 0.2 to 0.4 centimetres (0.08 to 0.16 in) thick at the stem apex; the stem is slightly thicker towards the base, and may be covered with hyphae that appear woolly (flocculose) or hairy (fibrillose). The surface of the stem may also be scaly – especially towards the base – or it may be covered with very small particles (granular). The flesh of this mushroom is white or pale yellow, with no distinctive taste or odor. [11] The spore print is white. It is considered inedible. [12]
Spores are thin-walled, smooth, and ellipsoidal or oval in shape. Viewed with a microscope, they appear translucent (hyaline), and stain red or blue with Melzer's reagent (inamyloid). Their dimensions are typically 7–10 by 5–7 µm; the spores contain a single large oil droplet. The spore-bearing cells, the basidia, are club-shaped, two- to four-spored, and 25–30 by 5–7 µm. [13] The presence of sterile cells called pleurocystidia (large cells found on the gill face in some mushrooms) is uncommon; specimens may contain few or abundant cheilocystidia (large sterile cells found on the gill edge) that are club-shaped, thin-walled and 39–87.5 by 8.5–16 µm in size. [11]
Cyptotrama asprata is a saprobic fungus, and grows on the decaying wood of deciduous and coniferous trees. Host species include white fir ( Abies concolor ), sugar maple ( Acer saccharum ) and other maple ( Acer ) species, grey alder ( Alnus oblongifolia ), beech ( Fagus ) species, spruce ( Picea ) species, ponderosa pine ( Pinus ponderosa ) and other pine ( Pinus ) species, poplar ( Populus ) and oak ( Quercus ) species. In temperate North America, specimens are typically collected between July through September. [11]
The species has a pantropical distribution, and is widely distributed in tropical regions of the world. [14] It has been collected from Australia, [15] southeastern Canada, [16] China, [13] [14] Costa Rica, [17] India, [18] Hawaii, [19] New Zealand, [20] Japan, [21] and the Russian Far East. [22] It is absent from Europe and Northwestern North America. [11]
Many other members of genus Cyptotrama are similar in appearance and differ from C. asprata by only one or two readily observable features. For example, C. granulosa is bright yellowish-brown (rather than bright or pale yellow in C. asprata); C. lachnocephala is ochre-colored; C. deseynesiana is cream-colored with brown scales; C. verruculosa has a "copper-rust-brown" cap; C. costesii has olive-colored pigments. Species may also be distinguished by differences in spore size and shape, although a considerable size range has been noted for C. asprata spores. [11]
Xerula megalospora is a species of gilled mushroom in the family Physalacriaceae.
Mythicomyces is a fungal genus in the family Mythicomycetaceae. A monotypic genus, it contains the single species Mythicomyces corneipes, first described by Elias Fries in 1861. The fungus produces fruit bodies with shiny yellowish-orange to tawny caps that are 1–3 cm (0.4–1.2 in) in diameter. These are supported by stems measuring 2–5.7 cm (0.8–2.2 in) long and 1–2 mm thick. A rare to uncommon species, it is found in northern temperate regions of North America and Europe, where it typically fruits in groups, in wet areas of coniferous forests. There are several species with which M. corneipes might be confused due to a comparable appearance or similar range and habitat, but microscopic characteristics can be used to reliably distinguish between them.
Scutellinia scutellata, commonly known as the eyelash cup, the Molly eye-winker, the scarlet elf cap, the eyelash fungus or the eyelash pixie cup, is a small saprophytic fungus of the genus Scutellinia. It is the type species of Scutellinia, as well as being the most common and widespread. The fruiting bodies are small red cups with distinct long, dark hairs or "eyelashes". These eyelashes are the most distinctive feature and are easily visible with a magnifying glass. The species is common in North America and Europe, and has been recorded on every continent. S. scutellata is found on rotting wood and in other damp habitats, typically growing in small groups, sometimes forming clusters. It is sometimes described as inedible, but its small size means it is not suitable for culinary use. Despite this, it is popular among mushroom hunters due to its unusual "eyelash" hairs, making it memorable and easy to identify.
Coprinopsis lagopus is a species of fungus in the family Psathyrellaceae. Until 2001, the species was known as Coprinus lagopus; advances in the understanding of phylogenetic relationships between the various coprinoid species led to a major reorganization of that genus. It is a delicate and short-lived fungus, the fruit bodies lasting only a few hours before dissolving into a black ink – a process called deliquescence. The vague resemblance of the young fruit body to the paw of a white rabbit has earned this species the common name harefoot mushroom.
Aureoboletus mirabilis, commonly known as the admirable bolete, the bragger's bolete, and the velvet top, is an edible species of fungus in the Boletaceae mushroom family. The fruit body has several characteristics with which it may be identified: a dark reddish-brown cap; yellow to greenish-yellow pores on the undersurface of the cap; and a reddish-brown stem with long narrow reticulations. Aureoboletus mirabilis is found in coniferous forests along the Pacific Coast of North America, and in Asia. Unusual for boletes, A. mirabilis sometimes appears to fruit on the wood or woody debris of Hemlock, suggesting a saprobic lifestyle. Despite occasional appearances to the contrary, Aureoboletus mirabilis is mycorrhizal, and forms close mutualistic associations with hemlock roots.
Xerocomellus zelleri, commonly known as Zeller's bolete, is an edible species of mushroom in the family Boletaceae. First described scientifically by American mycologist William Alphonso Murrill in 1912, the species has been juggled by various authors to several genera, including Boletus, Boletellus, and Xerocomus. Found solely in western North America from British Columbia south to Mexico, the fruit bodies are distinguished by their dark reddish brown to nearly black caps with uneven surfaces, the yellow pores on the underside of the caps, and the red-streaked yellow stems. The fungus grows in summer and autumn on the ground, often in Douglas fir forests or on their margins. The development of the fruit bodies is gymnocarpic, meaning that the hymenium appears and develops to maturity in an exposed state, not enclosed by any protective membrane.
Dendrocollybia is a fungal genus in the family Tricholomataceae of the order Agaricales. It is a monotypic genus, containing the single species Dendrocollybia racemosa, commonly known as the branched collybia or the branched shanklet. The somewhat rare species is found in the Northern Hemisphere, including the Pacific Northwest region of western North America, and Europe, where it is included in several Regional Red Lists. It usually grows on the decaying fruit bodies of other agarics—such as Lactarius and Russula—although the host mushrooms may be decayed to the point of being difficult to recognize.
Cantharellus lateritius, commonly known as the smooth chanterelle, is a species of edible fungus in the mushroom family Cantharellaceae. An ectomycorrhizal species, it is found in Asia, Africa, and North America. The species has a complex taxonomic history, and has undergone several name changes since its first description by American mycologist Lewis David de Schweinitz in 1822. The fruit bodies of the fungus are brightly colored yellow to orange, and usually highly conspicuous against the soil in which they are found. At maturity, the mushroom resembles a filled funnel with the spore-bearing surface along the sloping outer sides. The texture of the fertile undersurface (hymenium) of the caps is a distinguishing characteristic of the species: unlike the well-known golden chanterelle, the hymenium of C. lateritius is much smoother. Chemical analysis has revealed the presence of several carotenoid compounds in the fruit bodies.
Mycena nargan, commonly known as the Nargan's bonnet, is a species of fungus in the family Mycenaceae, and the sole member of the section Nargan in the genus Mycena. Reported as a new species in 1995, it is known predominantly from Southern Australia. The saprobic fungus produces mushrooms that grow on well-decayed wood, often on the underside of wood lying in litter. The dark chestnut-coloured caps are covered with white, easily removed scales, and reach diameters of up to 2 cm (0.8 in) wide. The pale, slender stems are up to 5 cm (2.0 in) long and have white scales at the base. On the underside of the cap, the cream-coloured gills are widely spaced and bluntly attached to the stem. The edibility of the mushroom is unknown.
Pholiota flammans, commonly known as the yellow pholiota, the flaming Pholiota, or the flame scalecap, is a basidiomycete agaric mushroom of the genus Pholiota. Its fruit body is golden-yellow in color throughout, while its cap and stem are covered in sharp scales. As it is a saprobic fungus, the fruit bodies typically appear in clusters on the stumps of dead coniferous trees. P. flammans is distributed throughout Europe, North America, and Asia in boreal and temperate regions. Its edibility has not been clarified.
Psilocybe makarorae is a species of psilocybin mushroom in the family Hymenogastraceae. Officially described as new to science in 1995, it is known only from New Zealand, where it grows on rotting wood and twigs of southern beeches. The fruit body (mushroom) has a brownish cap with lighter coloured margins, measuring up to 3.5 cm (1.4 in) wide. The cap shape is either conical, bell-shaped, or flat depending on the age of the mushroom, and it features a prominent umbo. Although the whitish stem does not form a true ring, it retains remnants of the partial veil that covers and protects the gills of young fruit bodies. P. makarorae mushrooms can be distinguished from the similar North American species Psilocybe caerulipes by microscopic characteristics such as the presence of cystidia on the gill faces (pleurocystidia), and cheilocystidia with more elongated necks. Based on the bluing reaction to injury, P. makarorae is presumed to contain the psychedelic compounds psilocybin and psilocin.
Suillus pungens, commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus Suillus. The fruit bodies of the fungus have slimy convex caps up to 14 cm (5.5 in) wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stem (stipe) up to 7 cm (2.8 in) long, and 2 cm (0.8 in) thick. On the underside on the cap is the spore-bearing tissue consisting of minute vertically arranged tubes that appear as a surface of angular, yellowish pores. The presence of milky droplets on the pore surface of young individuals, especially in humid environments, is a characteristic feature of this species. S. pungens can usually be distinguished from other similar Suillus species by differences in distribution, odor and taste. The mushroom is considered edible, but not highly regarded.
Crinipellis zonata, commonly known as the zoned Crinipellis or the zoned-cap Collybia, is a species of gilled mushroom in the family Marasmiaceae. Though considered a little brown mushroom of unknown edibility, it is distinctive because of its thick covering of coarse hairs, and differentiated from other members of Crinipellis by its slightly larger cap size, which reaches up to 25 mm (1.0 in) in diameter. The white gills on the underside of the cap are crowded closely together, and are free from attachment to the stem. Saprobic, it grows on the dead wood of deciduous trees from late summer to autumn. The fungus is found commonly in eastern North America, but has also been collected in Portugal and Korea. The variety C. zonata var. cremoricolor, found in eastern North America, may be distinguished microscopically by its longer spores.
Collybia tuberosa, commonly known as the lentil shanklet or the appleseed coincap, is an inedible species of fungus in the family Tricholomataceae, and the type species of the genus Collybia. Like the two other members of its genus, it lives on the decomposing remains of other fleshy mushrooms. The fungus produces small whitish fruit bodies with caps up to 1 cm (0.4 in) wide held by thin stems up to 5 cm (2.0 in) long. On the underside of the cap are closely spaced white gills that are broadly attached to the stem. At the base of the stem, embedded in the substrate is a small reddish-brown sclerotium that somewhat resembles an apple seed. The appearance of the sclerotium distinguishes it from the other two species of Collybia, which are otherwise very similar in overall appearance. C. tuberosa is found in Europe, North America, and Japan, growing in dense clusters on species of Lactarius and Russula, boletes, hydnums, and polypores.
Collybia cookei is a species of fungus in the family Tricholomataceae, and one of three species in the genus Collybia. It is known from Europe, Asia, and North America. The fungus produces fruit bodies that usually grow on the decomposing remains of other mushrooms, like Meripilus giganteus, Inonotus hispidus, or species of Russula; occasionally fruit bodies are found on rich humus or well-decayed wood. The fungus produces small white mushrooms with caps up to 9 mm (0.35 in) in diameter, supported by thin stems that originate from a yellowish-brown sclerotium. The mushroom is difficult to distinguish from the other two species of Collybia unless an effort is made to examine the sclerotia, which is usually buried in the substrate. The edibility of the mushroom has not been determined.
Collybia cirrhata is a species of fungus in the family Tricholomataceae of the order Agaricales. The species was first described in the scientific literature in 1786, but was not validly named until 1803. Found in Europe, Northern Eurasia, and North America, it is known from temperate, boreal, and alpine or arctic habitats. It is a saprobic species that grows in clusters on the decaying or blackened remains of other mushrooms. The fruit bodies are small, with whitish convex to flattened caps up to 11 mm in diameter, narrow white gills, and slender whitish stems 8–25 mm long and up to 2 mm (0.08 in) thick. C. cirrhata can be distinguished from the other two members of Collybia by the absence of a sclerotium at the base of the stem. The mushroom is of unknown edibility.
Entoloma murrayi, commonly known as the yellow unicorn Entoloma or the unicorn pinkgill, is a species of fungus in the Entolomataceae family. First described from New England (USA) in 1859, the species is found in eastern North America, Central and South America, and southeast Asia, where it grows on the ground in wet coniferous and deciduous forests. The fungus produces yellow mushrooms that have a characteristic sharp umbo on the top of a conical cap. The mushroom is inedible and may be poisonous. Other similar species can be distinguished from E. murrayi by differences in color, morphology, or microscopic characteristics.
Boletus curtisii is a species of fungus in the family Boletaceae. It produces small- to medium-sized fruit bodies (mushrooms) with a convex cap up to 9.5 cm (3.7 in) wide atop a slender stem that can reach a length of 12 cm (4.7 in). In young specimens, the cap and stem are bright golden yellow, although the color dulls to brownish when old. Both the stem and cap are slimy or sticky when young. On the underside of the cap are small circular to angular pores. The mushroom is edible, but not appealing. It is found in eastern and southern North America, where it grows in a mycorrhizal association with hardwood and conifer trees. Once classified as a species of Pulveroboletus, the yellow color of B. curtisii is a result of pigments chemically distinct from those responsible for the yellow coloring of Pulveroboletus.
Strobilurus tenacellus, commonly known as the pinecone cap, is a species of agaric fungus in the family Physalacriaceae. It is found in Asia and Europe, where it grows on the fallen cones of pine and spruce trees. The fruit bodies (mushrooms) are small, with convex to flat, reddish to brownish caps up to 15 mm (0.6 in) in diameter, set atop thin cylindrical stems up to 4–7.5 cm (1.6–3.0 in) long with a rooting base. A characteristic microscopic feature of the mushroom is the sharp, thin-walled cystidia found on the stipe, gills, and cap. The mushrooms, sometimes described as edible, are too small to be of culinary interest. The fungus releases compounds called strobilurins that suppress the growth and development of other fungi. Derivatives of these compounds are used as an important class of agricultural fungicides.
Conocybe aurea is a basidiomycete fungus in the family Bolbitiaceae.
