Coprinellus is a genus of mushroom-forming fungi in the family Psathyrellaceae. The genus was circumscribed by Petter Karsten in 1879. Most Coprinellus species were transferred from the once large genus Coprinus. Molecular studies published in 2001 redistributed Coprinus species to Psathyrella, or the segregate genera Coprinopsis and Coprinellus. As of January 2016, Index Fungorum accepts 62 species of Coprinellus.
Tricholomopsis is a genus of fungi closely related to the large genus Tricholoma. Its best known member and type species is Tricholomopsis rutilans. The name means appearing like Tricholoma. The genus has a widespread distribution, and contains about 30 species. Tricholomopsis was described in 1939 by American mycologist Rolf Singer.
Inocybe hystrix is an agaric fungus in the family Cortinariaceae. It forms mycorrhiza with surrounding deciduous trees. Fruit bodies are usually found growing alone or in small groups on leaf litter during autumn months. Unlike many Inocybe species, Inocybe hystrix is densely covered in brown scales, a characteristic that aids in identification. The mushroom also has a spermatic odour that is especially noticeable when the mushroom is damaged or crushed.
Leucopaxillus is a genus of fairly large white-spored gilled mushrooms which are found worldwide growing on the ground in woodlands. These are saprotrophs, but may sometimes be ectomycorrhizal. Less than ten species of Leucopaxillus are known to grow in North America. No species of Leucopaxillus are known to be poisonous, but they do not have an appealing taste or texture. The widespread genus contains about 15 species.
Resupinatus is a genus of fungi in the family Tricholomataceae. Species are saprobic, and often found growing on the underside of decaying wood or sides of decaying woody substrates. The generic name is derived from the Latin resupinus.
Coprinellus deliquescens is a species of mushroom in the Psathyrellaceae family. It was first described as Agaricus deliquescens in 1790 by French mycologist Bulliard before being transferred to the genus Coprinellus in 1879 by Petter Karsten.
Coprinellus congregatus is a species of mushroom in the Psathyrellaceae family. It was first described in 1782 as Agaricus congregatus by French mycologist Jean Baptiste François Pierre Bulliard, and later transferred to the genus Coprinellus in 1879 by Petter Karsten. They are found in North America and Europe.
Mycena cinerella, commonly known as the mealy bonnet, is an inedible species of mushroom in the family Mycenaceae. It is found in Europe and the United States, where it grows in groups on fallen leaves and needles under pine and Douglas fir. The small grayish mushrooms have caps that are up to 1.5 cm (0.6 in) wide atop stipes that are 5 cm (2.0 in) long and 2.5 mm (0.10 in) thick. Its gills are grayish-white and adnate, with a "tooth" that runs slightly down the stipe. The fungus has both two- and four-spored basidia. As its common name suggests, it smells mealy.
Macrocybe is a genus of fungi in the family Tricholomataceae. The genus contains seven species, widely distributed in tropical regions worldwide.
Leucopholiota decorosa is a species of fungus in the Tricholomataceae family of mushrooms. Commonly known as the decorated pholiota, it is distinguished by its fruit body which is covered with pointed brown, curved scales on the cap and stem, and by its white gills. Found in the eastern United States, France, and Pakistan, it is saprobic, growing on the decaying wood of hardwood trees. L. decorosa was first described by American mycologist Charles Horton Peck as Agaricus decorosus in 1873, and the species has been transferred to several genera in its history, including Tricholoma, Tricholomopsis, Armillaria, and Floccularia. Three American mycologists considered the species unique enough to warrant its own genus, and transferred it into the new genus Leucopholiota in a 1996 publication. Lookalike species with similar colors and scaly fruit bodies include Pholiota squarrosoides, Phaeomarasmius erinaceellus, and Leucopholiota lignicola. L. decorosa is considered an edible mushroom.
Tricholoma imbricatum is a species of agaric fungus in the family Tricholomataceae. Commonly known as the matt knight, it is found in Europe and North America, where it grows on the ground in coniferous forests. Fruit bodies have a brown to reddish-brown cap up to 9 cm (3.5 in) in diameter, and a stipe that is 3.5 to 4.5 cm long by 1.0 to 1.2 cm thick. The gills are initially whitish in color before developing reddish-brown spots.
Porpoloma umbrosum, commonly known as the amyloid tricholoma, is a species of fungus in the family Tricholomataceae, and the type species of the genus Porpoloma. It was first described scientifically by mycologists Alexander H. Smith and Maurice B. Walters in 1943 as a species of Tricholoma. Rolf Singer transferred it to Porpoloma in 1962. The mushroom is found in North America, where it fruits singly or in small groups under conifer trees. Although it resembles Tricholoma species, it is distinguished from that genus by its amyloid spores.
Albomagister is a genus of fungi in the family Tricholomataceae. The genus contains just one named species known from Tennessee and North Carolina, however two other undescribed species have been sequenced. Albomagister was described by mycologists Marisol Sánchez-García, Joshua Birkebak & P. Brandon Matheny in 2014 with Albomagister subaustralis as the type species.
Corneriella is a genus of fungi in the family Tricholomataceae. The genus contains two species known from the United States and Thailand, and at least four others have been detected by DNA sequencing. Corneriella was described the mycologist Marisol Sánchez-García in 2014 with Corneriella bambusarum as the type species.
Pseudotricholoma is a genus of fungi in the family Tricholomataceae. The genus contains two species known from the Canada, the United States and Europe. Pseudotricholoma was described the mycologists Marisol Sánchez-García and P. Brandon Matheny in 2014 with Pseudotricholoma umbrosum as the type species.
Tricholoma acerbum is a mushroom of the agaric family Tricholomataceae. It is found in Europe and North America.
