Description

Psathyrella ammophila, commonly known as the Dune Brittlestem, is a species of agaric fungus in the family Psathyrellaceae. It is characterized by its fragile, brittle fruiting body and its preference for sandy habitats, particularly dunes. The cap is typically conical to convex, with a smooth surface and a color ranging from pale ochre to tan. The gills are closely spaced and adnate to adnexed, initially pale but darkening to brown as the spores mature. The stem is slender and fragile, often with a slightly bulbous base. This species is found in coastal regions, where it grows in association with sand dunes and other sandy substrates.
