Tricholoma is a genus of fungus that contains many fairly fleshy white-spored gilled mushrooms which are found worldwide generally growing in woodlands. These are ectomycorrhizal fungi, existing in a symbiotic relationship with various species of coniferous or broad-leaved trees. The generic name derives from Ancient Greek: τριχο-, romanized: tricho-, lit. 'hair' and Ancient Greek: λῶμα, romanized: loma, lit. 'fringe, border' although only a few species have shaggy caps which fit this description.
Tricholoma equestre or Tricholoma flavovirens, commonly known as the man on horseback or yellow knight is a widely eaten but arguably toxic fungus of the genus Tricholoma that forms ectomycorrhiza with pine trees.
Tricholoma sulphureum, also known as the stinker, sulphur knight or gas agaric, is an inedible or mildly poisonous mushroom found in woodlands in Europe. It has a distinctive bright yellow colour and an unusual smell likened to coal gas. It occurs in deciduous woodlands in Europe from spring to autumn.
Tricholoma magnivelare, commonly known as the matsutake, white matsutake, ponderosa mushroom, pine mushroom, or American matsutake, is a gilled mushroom found East of the Rocky Mountains in North America growing in coniferous woodland. These ectomycorrhizal fungi are typically edible species that exist in a symbiotic relationship with various species of pine, commonly jack pine. They belong to the genus Tricholoma, which includes the closely related East Asian songi or matsutake as well as the Western matsutake and Meso-American matsutake.
Tricholoma pardinum, commonly known as spotted tricholoma, tiger tricholoma, tigertop, leopard knight, or dirty trich, is a gilled mushroom widely distributed across North America, Europe, and parts of Asia. It is generally found in beech woodland in summer and autumn. Two subspecies have been described from southern Europe. First officially described by Christiaan Hendrik Persoon in 1801, T. pardinum has had a confusing taxonomic history that extends over two centuries. In 1762, German naturalist Jacob Christian Schäffer described the species Agaricus tigrinus with an illustration corresponding to what is thought to be T. pardinum, and consequently, the name Tricholoma tigrinum has been used erroneously in some European field guides.
Tricholoma saponaceum, also known as the soap-scented toadstool, soapy tricholoma, soapy knight or soap tricholoma is an inedible mushroom found in woodlands in Europe and North America.
Tricholoma mutabile is a mushroom of the agaric genus Tricholoma. Found in Yuba County, California, it was first described scientifically in 1996. It has a grayish convex cap that is 3 to 9 cm wide, a white stalk measuring 5 to 10 cm long by 0.9 to 2.5 cm thick. The white gills are sinuate, and turn pale golden brown in maturity.
Tricholoma nigrum is a mushroom of the agaric genus Tricholoma. It was described as new to science in 1996 from a collection made on the Oregon Coast where it occurred with Pinus contorta. It has also been found in an old-growth conifer forest.
Tricholoma virgatum, commonly known as the ashen knight, is a mushroom of the agaric genus Tricholoma. It was first described scientifically as Agaricus virgatus by Elias Fries in 1818, and later transferred to the genus Tricholoma by Paul Kummer in 1871. It is found in the deciduous and coniferous forests of Europe, North America, and China. The mushroom is inedible, speculated to be poisonous, and has a bitter and peppery taste and musty odor.
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, which is often scaly, and ranges from 6–18 cm in diameter, and a stipe that is 3.5–12 cm long by 1–3 cm thick. The gills are initially whitish in color before developing reddish-brown spots. The spores are white.
Tricholoma vaccinum, commonly known as the russet scaly tricholoma, the scaly knight, or the fuzztop, is a fungus of the agaric genus Tricholoma. It produces medium-sized fruit bodies (mushrooms) that have a distinctive hairy reddish-brown cap with a shaggy margin when young. The cap, which can reach a diameter of up to 6.5 cm (2.6 in) wide, breaks up into flattened scales in maturity. It has cream-buff to pinkish gills with brown spots. Its fibrous, hollow stipe is white above and reddish brown below, and measures 4 to 7.5 cm long. Although young fruit bodies have a partial veil, it does not leave a ring on the stipe.
Tricholoma ustale, commonly known as the burnt knight, is a species of mushroom in the large genus Tricholoma. It is found in Asia, Europe, and North America, though those from North America may represent one or more different species.
Tricholoma caligatum is a mushroom of the agaric genus Tricholoma. It is a large species with a distinct sheathing ring on the stem, found in mycorrhizal association with various trees throughout the Mediterranean. It is sometimes referred to as the European Matsutake, though it is certainly gastronomically inferior to the true Matsutake, a related species highly prized in Japan.
Tricholoma griseoviolaceum is a mushroom of the agaric genus Tricholoma. It was described as new to science in 1996.
Tricholoma inamoenum is a mushroom of the agaric genus Tricholoma found through the Northern Hemisphere, particularly under conifers. It is poisonous, and is characterized by an unpleasant odor resembling coal gas or tar. • Analysis of the volatile compounds emanating from fresh sporocarps using solid phase microextraction (SPME) showed the odor compounds responsible for the coal tar odor of this mushroom are 1-octen-3-ol and indole.
Tricholoma pessundatum is a mushroom of the agaric genus Tricholoma. First described as Agaricus pessundatus by Elias Magnus Fries in 1821, it was transferred to the genus Tricholoma by Lucien Quélet in 1872.
Tricholoma vernaticum is an agaric fungus of the genus Tricholoma native to the Pacific Northwest region of the United States. The fungus was originally described in 1976 as a species of Armillaria when that genus was more inclusive; it received its current name twenty years later. The stout fruit bodies (mushrooms) have moist white to grayish caps, a membranous ring on the stipe, and an odor resembling cucumbers. Mycorrhizal with conifers, the fungus fruits in the spring or early summer, with its mushrooms appearing on the ground singly or in groups at high elevations, often at the edge of melting snowbanks. The edibility of the mushroom is unknown, but it has a strong unpleasant odor and a mealy taste.
Tricholoma sejunctum is a mushroom that appears across much of the Northern Hemisphere and is associated with pine forests.
