In many (but not all) field guides Psathyrella candolleana is recorded as 'edible but not worthwhile', while other field guides record it as inedible or edibility unknown.

The stipe is 2–7 cm tall and 3–7 mm wide, white, smooth, hollow, and bulging at the base. Fruiting occurs in clusters at the base of hardwood stumps. It is considered edible but of low quality, with fragile flesh and being difficult to identify. Similar species include Psathyrella carbonicola, P.

Psathyrella corrugis, is the type species of the basidiomycete fungus genus Psathyrella and family Psathyrellaceae. Originally described from Europe as Agaricus corrugis, the species is considered non-toxic but lacking in flesh, flavor and texture. It is inedible.

Flesh of the cap and stem is pale, thin, and brittle. Neither the taste nor the odour of the mushroom is distinctive, and it is considered inedible, though not particularly noted as being toxic. Conocybe dunensis is a similar species that is mainly differentiated from P. ammophila by the rust colour of its gills.
