Collybia nuda, commonly known as the blewit or wood blewit and previously described as Lepista nuda and Clitocybe nuda, is an edible mushroom native to Europe and North America. Described by Pierre Bulliard in 1790, it was also known as Tricholoma nudum for many years. It is found in both coniferous and deciduous woodlands. It is a fairly distinctive mushroom that is widely eaten. It has been cultivated in Britain, the Netherlands and France. This species was reassigned to the genus Collybia in 2023.
William Alphonso Murrill was an American mycologist, known for his contributions to the knowledge of the Agaricales and Polyporaceae. In 1904, he became the assistant Curator at the New York Botanical Garden (NYBG). He, along with the NYBG, founded the journal Mycologia and was its first editor for 16 years. Murrill was known to travel extensively to describe the mycota of Europe and the Americas. He traveled along the East Coast, Pacific Coast, Mexico and the Caribbean. Although Murrill was a very influential person at the NYBG, having worked his way up to become assistant director in 1908, his rather eccentric personality caused problems with his job. He went on annual collecting trips to Mexico, the Caribbean, Europe, and South America, sometimes, without informing any of his colleagues prior. These trips resulted in a cumulative total of 70,000 specimens, 1,400 of which are deposited in the NYBG. Murrill might have issued an exsiccata series under the title Polyporaceae of North America.
Gymnopus dryophilus is a mushroom commonly found in temperate woodlands of Europe and North America. It is generally saprophytic, but occasionally also attacks living wood. It belongs to section Levipedes of the genus, being characterized by a smooth stem having no hairs at the base. Until recently it was most frequently known as Collybia dryophila.
Cyptotrama asprata, commonly known as the golden-scruffy collybia or spiny woodknight 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.
Rhodocollybia is a genus of Basidiomycete mushroom. Species in this genus, formerly classified as a subgenus in Collybia, have fairly large caps, and have a pinkish-tinted spore print. Microscopically, they are characterized by having spores and basidia that are dextrinoid—staining deep reddish to reddish-brown with Melzer's reagent when tested for amyloidity. Rhodocollybia species are commonly found in temperate North America and Europe, and infrequently in Central and South America.
Collybia is a genus of mushrooms in the family Tricholomataceae. The genus has a widespread but rare distribution in northern temperate areas, and contains three species that grow on the decomposing remains of other mushrooms.
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.
Gymnopus is a genus of fungus in the family Omphalotaceae. The genus has a widespread, cosmopolitan distribution and contains about 300 species.
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.
Connopus is a fungal genus in the family Omphalotaceae. The monotypic genus was circumscribed in 2010 to accommodate the species Connopus acervatus, formerly in the genus Gymnopus. It is found in North American and Europe, where it grows in dense clusters on decaying wood. It is regarded as inedible.
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.
Rhodocollybia butyracea, commonly known as the buttery collybia, is a species of fungus in the mushroom family Omphalotaceae. It has a number of subspecies.
Roy Edward Halling is an American mycologist.
Gymnopus moseri is a European species of agaric fungus in the family Omphalotaceae. It was described as new to science in 1997 by mycologists Vladimír Antonín and Machiel Noordeloos from collections made in Sweden. Fruit bodies of the holotype collection were found growing among Polytrichum and in coarse humus and leaves under birch (Betula) and willow (Salix). Collybia moseri is a synonym proposed by Marcel Bon in 1998. The specific epithet moseri honours Austrian mycologist Meinhard Michael Moser.
Gymnopus fusipes is a parasitic species of gilled mushroom which is quite common in Europe and often grows in large clumps. It is variable but easy to recognize because the stipe soon becomes distinctively tough, bloated and ridged.
Collybiopsis peronata, also known as wood woolly-foot, is a species of gilled mushroom which is common in European woods.
Gymnopus herinkii is a rare species of mushroom-forming fungus in the family Omphalotaceae. It was described in 1998 by mycologists Vladimír Antonín and Machiel Noordeloos. The type specimen was from a collection made in the Lenora region of Bohemia, made by Czech mycologists Jiří Kubička and Josef Herink in 1952; the latter is acknowledged in the species epithet. Marcel Bon proposed a transfer to the genus Collybia in 1998.
Collybiopsis confluens, commonly known as the clustered toughshank, is a type of mushroom from the Omphalotaceae family. The fruiting body appears from summer until autumn in deciduous and coniferous forests. Collybiopsis confluens is not an edible mushroom.
