Psathyrella spadicea

Species of fungus

Psathyrella spadicea or Homophron spadiceum, commonly known as the chestnut brittlestem, is a species of agaric fungus in the family Psathyrellaceae. The fungus was originally described by German mycologist Jacob Christian Schäffer in 1783 as Agaricus spadiceus. Rolf Singer transferred it to the genus Psathyrella in 1951, in which it was classified in the section Spadiceae. In 2015 Örstadius & Larsson recreated the genus Homophron for a group of psathyrelloid mushrooms with no veil and with light-coloured spores, and P. spadicea was moved to the new genus.
