Phaeocollybia
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). As of January 2026, the genus contained about 90 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.
