Pseudotricholoma umbrosum, commonly known as the amyloid tricholoma, [1] is a species of fungus in the family Tricholomataceae, and the type species of the genus Pseudotricholoma . It was first described scientifically by mycologists Alexander H. Smith and Maurice B. Walters in 1943 as a species of Tricholoma . [2] Rolf Singer transferred it to Porpoloma (subgenus Pseudotricholoma) in 1962. [3] The mushroom is found in North America, where it fruits singly or in small groups under conifer trees. Although it resembles a Tricholoma species, it is distinguished from that genus by its amyloid spores. [1]

<i>Entoloma sinuatum</i> Species of poisonous fungus in the family Entolomataceae found across Europe and North America

Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. The largest mushroom of the genus of pink-spored fungi known as Entoloma, it is also the type species. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands, sometimes in the form of fairy rings. Solid in shape, they resemble members of the genus Tricholoma. The ivory to light grey-brown cap is up to 20 cm (7.9 in) across with a margin that is rolled inward. The sinuate gills are pale and often yellowish, becoming pink as the spores develop. The thick whitish stem has no ring.

<span class="mw-page-title-main">Tricholomataceae</span> Family of fungi

The Tricholomataceae are a large family of fungi within the order Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae.

<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 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>Leucopaxillus</i> Genus of fungi

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.

<i>Leucopholiota decorosa</i> Species of fungus

Leucopholiota decorosa is a species of fungus in the mushroom family Tricholomataceae. 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.

<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 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 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 ustale</i> Species of fungus

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.

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

Tricholoma aestuans is a mushroom of the agaric genus Tricholoma. First described formally by Elias Magnus Fries in 1821, it was transferred to the genus Tricholoma by Claude Casimir Gillet in 1874.

Tricholoma atrodiscum is a mushroom of the agaric genus Tricholoma. It was described as new to science in 1989.

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

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

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

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

<i>Hygrophorus russula</i> Species of fungus

Hygrophorus russula, commonly known as the pinkmottle woodwax, false russula, or russula-like waxy cap, is a fungus native to North America and Europe.

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

Tricholoma roseoacerbum is an agaric fungus of the genus Tricholoma. The species was first described by Italian mycologist Alfredo Riva in 1979 as Tricholoma pseudoimbricatum var. roseobrunneum, but that name competed with an older homonym, William Murrill's 1913 Tricholoma roseobrunneum. Riva published the species with a new replacement name in 1984. T. roseoacerbum is found in Europe and northeastern North America. The specific epithet roseoacerbum alludes to the rosy colouration in its cap, and overall resemblance to T. acerbum. This species is probably conspecific with Tricholoma radotinense Pilát & Charvát (1959).
