Description
The species can be described as follows:
The cap has a powdery covering (a pruina), is initially whitish and convex and later becomes brownish grey and expands to be flat. It grows to about 2.5 cm in diameter. The gills are whitish and distant, and broadly adnate to the stem, or slightly decurrent. The spore powder is white. The rigid stem can grow to about 12 cm long by about 2 mm in diameter. It is white at the top and dark brown to black lower down, with a puinose covering of short white hairs. The smell and taste are not distinctive. The spores are lemon-shaped to ellipsoid and measure roughly 9-12 μm x 5-7 μm.
Range & habitat
This mushroom grows on rhizomes of bracken (Pteridium aquilinum) and probably other ferns. It is widespread but rare in northern and western Europe and has been reported from North Africa, North America, and the Altai Mountains.
