, resembling a little mushroom (i.e. Agaricus) is also found in sand-dune systems and, just as species of Psathyrella, it possesses purplish black spores. However, the cap is ochraceous yellow with a whitish margin formed of veil fragments. The stem is white becoming yellow with age and possesses a narrow, white striate ring. The spores are ellipsoid and measure 8-9 × 4-5 µm and it has filamentous cells in the cap. Unlike P. ammophila it is not confined to sand-dune systems but it is also to be found in pastures and on heaths.
