''Phaeocollybia'' is a genus of fungi in the family Hymenogastraceae.〔 They are characterized by producing fruit bodies (mushrooms) with umbonate caps and rough brown spores. The genus is widely distributed (especially in temperate regions), and contains about 50 species.〔 They are known for a long stipe which continues down into the ground, known as a ''rooting'' stipe or pseudorhiza formed as the fruitbody grows up from the subterranean colonized roots well below the organic soil layer. The genus is primarily mycorrhizal but may also be somewhat parasitic on forest trees. Molecular phylogenetic work during the 2000s suggests a close relationship to ''Galerina''. ==Taxonomy== The genus was circumscribed by mycologist Roger Heim in 1931.〔 The name ''Phaeocollybia'' is conserved against the earlier but obscure name ''Quercella''. ''Phaeocollybia'' means ''dusky Collybia'' which actually refers to the brownish spore print in contrast to the white spore print of ''Collybia'' in the traditional sense.
