Habitat:
Ecology: Saprobic; growing scattered to gregariously or in small clusters in hardwood or conifer forests, often near woody debris; spring and early summer; apparently widely distributed in North America
Notes:
Psathyrella spadiceogrisea is a large, springtime Psathyrella, appearing in both hardwood and conifer forests. Aside from its larger size, it is virtually indistinguishable from Psathyrella pseudovernalis in macroscopic features; both species feature brown caps, wisps of veil material along the cap margin, dark brown spore prints, and snap-able white stems. Under the microscope, however, Psathyrella spadiceogrisea features utriform (rather than fusoid-ventricose) hymenial cystidia--and its gill edges bear inconspicuous (rather than conspicuous) sphaeropedunculate elements--
