Tricholoma equestre

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' [1] although only a few species (such as T. vaccinum ) have shaggy caps which fit this description.

The most sought out species are the East Asian Tricholoma matsutake , also known as matsutake or songi, and the North American Tricholoma magnivelare species complex, also known as "ponderosa mushroom", "American matsutake", or "pine mushroom". Others are safe to eat, such as Tricholoma terreum , but there are a few poisonous members, such as T. pardinum , T. tigrinum and T. equestre .

Many species originally described within Tricholoma have since been moved to other genera. These include the Wood blewit ( Clitocybe nuda ), previously Tricholoma nudum, blewit ( Clitocybe saeva ), previously Tricholoma personatum, and St George's mushroom ( Calocybe gambosa ) previously Tricholoma gambosum.

Tricholomalides are neurotrophic diterpenoids isolated from species of Tricholoma. [2]

Matsutake, Tricholoma matsutake, is a species of choice edible mycorrhizal mushroom that grows in Eurasia and North America. It is prized in Japanese cuisine for its distinct spicy-aromatic odor.

<i>Collybia nuda</i> Species of mushroom

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.

<i>Tricholoma equestre</i> Species of fungus

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.

<i>Tricholoma argyraceum</i> Species of fungus

Tricholoma argyraceum is a grey-capped mushroom of the large genus Tricholoma. It has been often confused with the similar-looking Tricholoma scalpturatum.

<i>Tricholoma sulphureum</i> Species of fungus

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.

<i>Tricholoma magnivelare</i> Species of fungus

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 (T. murrillianum) and Meso-American matsutake (T. mesoamericanum).

<i>Tricholoma pardinum</i> Species of agaric fungus endemic to North America, Europe, and parts of Asia

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.

<i>Tricholoma terreum</i> Species of fungus

Tricholoma terreum, commonly known as the grey knight or dirty tricholoma, is a grey-capped mushroom of the large genus Tricholoma. It is found in coniferous woodlands in Europe, and has also been encountered under introduced pine trees in Australia and New Zealand. It is regarded as edible. A 2014 article speculated that it may be poisonous, but Sitta et al. in 2016 published in the same journal a counter article demonstrating the unfounded nature of such speculation.

<i>Tricholoma saponaceum</i> Species of fungus

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.

<i>Agaricus silvaticus</i> Species of fungus

Agaricus silvaticus, otherwise known as the scaly wood mushroom, blushing wood mushroom, or pinewood mushroom, is a species of mushroom often found in groups in coniferous forests from early summer, or September through to November in Europe, North Africa and North America.

<i>Tricholoma album</i> Species of fungus

Tricholoma album, commonly known as the white knight, is an all-white mushroom of the large genus Tricholoma. It is found in Europe, India, and possibly North America. The cap and gills are white. The whitish stipe has no ring.

<i>Tricholoma portentosum</i> Species of fungus

Tricholoma portentosum, commonly known as the charbonnier, streaked tricholoma, or sooty head, in North America, is a grey-capped edible mushroom of the large genus Tricholoma. It is found in woodlands in Europe and North America.

<i>Tricholoma tigrinum</i> Species of fungus

Tricholoma tigrinum is a gilled mushroom. First described under the name Agaricus tigrinus by Jacob Christian Schäffer in 1774, the species was transferred to the genus Tricholoma in 1871 by Paul Kummer.

<i>Tricholoma myomyces</i> Species of fungus

Tricholoma myomyces is a mushroom of the agaric genus Tricholoma, usually considered to be a synonym of Tricholoma terreum. The species was first described scientifically by Christian Hendrik Persoon in 1794 as Agaricus myomyces, and later transferred to the genus Tricholoma by Danish mycologist Jakob Emanuel Lange in 1933. It is found in Europe and northern North America.

<i>Tricholoma atrosquamosum</i> Species of fungus

Tricholoma atrosquamosum, commonly known as dark-scaled knight, is an edible gilled mushroom native to Europe. The grey-capped fruit bodies are generally found singly or in small groups in deciduous woodland on chalk-based soils.

<i>Tricholoma imbricatum</i> Species of fungus

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.

<i>Tricholoma vaccinum</i> Fungus of the agaric genus Tricholoma

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.

<i>Tricholoma caligatum</i> Species of fungus

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.
