The Tricholomataceae are a family of fungi in the order Agaricales. A 2008 estimate placed 78 genera and 1020 species in the family.[1] Subsequent molecular research, based on cladistic analysis of DNA sequences, has however found that this wide interpretation of the Tricholomataceae renders the family polyphyletic and is no longer tenable.
In 2014, Sánchez-García and colleagues proposed a revised classification of the Tricholomataceae with just seven genera: Leucopaxillus, Tricholoma, Dennisiomyces, Porpoloma, and the newly circumscribed genera Corneriella, Pogonoloma (now moved to the Pseudoclitocybaceae), and Pseudotricholoma.
Of the genera formerly placed in the Tricholomataceae, Amparoina is considered a synonym of Mycena; Callistosporium (with Pleurocollybia as a synonym) and Macrocybe have been moved to the Callistosporiaceae Catathelasma has been moved to the Biannulariaceae; Phyllotopsis and Tricholomopsis to the Phyllotopsidaceae; Leucopholiota and Squamanita to the Squamanitaceae; Pseudoclitocybe, Musumecia, and Pogonoloma to the Pseudoclitocybaceae; Cantharellopsis to the Rickenellaceae; Arthromyces to the Lyophyllaceae; and Hygroaster and Melanomphalia to the Hygrophoraceae;
Following changes to the International Code of Nomenclature for algae, fungi, and plants, the practice of giving different names to teleomorph and anamorph forms of the same fungus has been discontinued. As a result two anamorphic genera referred to the Tricholomataceae become synonyms of their teleomorphs: Tilachlidiopsis becomes a synonym of Dendrocollybia and Nothoclavulina a synonym of Arthrosporella.
Currently (2023) the following ten genera are accepted in the Tricholomataceae sensu stricto: Albomagister, Corneriella, Dennisiomyces, Dermoloma, Leucopaxillus, Porpoloma, Pseudobaeospora, Pseudoporpoloma, Pseudotricholoma, and Tricholoma. An additional eleven genera are related, but not yet assigned to a family, and further genera await research. All are listed below.
thumb|right|Albomagister subaustralisalt=A group of seven grey-brown mushrooms of varied size growing in oak leaves, three of them having been keeled over to show their gills. Their cap's margin is rolled, the gills adnate, and the stem widens toward the base.|thumb|right|Clitocybe nebularisalt=Three mushrooms on the ground, one has been picked and is lying with thestem pointing upwards; the caps are dark brown and the gills and stems, are a dirty whitish color.|thumb|right|Dermoloma cuneifoliumalt=Three copper-colored mushrooms seen from above. They are all different size and form a tight clump, with their caps overlapping. Said caps are glistening with humidity, and have a depressed center and a lightly striated margin.|thumb|right|Fayodia pseudoclusilisalt=Side view of a single-thick stemmed, pale lilac mushroom growing amongst thick clubmoss. It has irregular-looking gills and a textured stem. Its cap is not very flat and the other end can be seen curving above the rest.|thumb|right|Lepista nudaalt=A pair of bright white funnel mushroom, slightly overexposed from the flash. One is a young conical specimen with a rolled margin, laid to its side to show the fine white gills. The other is much wider and less regular, with a markedly wavy, unrolled margin.|thumb|right|Leucopaxillus giganteusalt=A mushroom with a small cap shaped like a round-tipped cone. It is seen from above, with a delicate stem and gills quite visible through the cap, making brown marks down it.|thumb|right|Mycenella bryophilaalt=A dirty-gray mushroom with white marks and a depressed center, growing amongst grass and clubmoss. The bottom of the depression is almost black and contains water.|thumb|right|Omphalina griseopallidaalt=Three lilac to purple mushroom have been couched to the side, showing their gills and the flaky texture of the stem, whose base is covered in thick hair.|thumb|right|Pseudobaeospora sp.alt=A pair of mushroom growing from a bed of clubmoss, the caps brown and slightly depressed at their center and growing paler to almost white at the margin, with a thick stem.|thumb|right|Pseudoomphalina pachyphyllathumb|right|alt=Several translucent, fleshy mushrooms growing from an unearthed root shown on a piece of fabric.|Rimbachia bryophilathumb|right|alt=A yellowish mushroom emerging from the ground, its cap still covered in dirt lifted by its growth.|Tricholoma equestre
