Homophron spadiceum is a species of fungus that belongs to the family Psathyrellaceae. It is characterized by its small to medium-sized fruiting bodies with a bell-shaped to convex cap that ranges in color from reddish-brown to dark brown, and a slender stem. In St. Petersburg, Leningrad Oblast, and north-western Russia, Homophron spadiceum typically grows on rich soil, often in association with deciduous trees, particularly birch and aspen. It fruits from late summer to early autumn, forming scattered or small groups of mushrooms. The species is considered rare in the region, but can be found in certain areas with suitable habitat.
