Psathyrella microrrhiza, also known as the Tiny Psathyrella, is a small, delicate agaric with a hygrophanous cap. Initially, it has scattered white fibrils or fibrillose scales on the outer part of the cap, which persist at the margin. This mushroom grows along roadsides in forests or on ruderal sites, often on remnants of wood or on leaf litter.

Cap initially obtuse-conic, progressing to campanulate or convex-umbonate as it matures. The cap is initially adorned with scattered white fibrils or fibrillose scales on the outer part, which persist along the margin. When drying, the cap may exhibit a pinkish tinge around the margin, and the gill edge may sometimes appear pinkish and flocculose. It is hygrophanous, medium-brown fading to pale buff-brown. Gills adnexed, moderately broad, close to crowded, pale dingy-buff, becoming brownish-grey in age. Stem slender, thin, fragile, stuffed at maturity, more or less equal and may have veil remnants present in the lower part of the stem. Spore print dark brown to purple-brown.

Microscopic Features: Spores measure 11-14 x 6-7 μm and are smooth in shape, featuring a germ pore.

Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we strongly advise against consuming wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.
