features

Macroscopic features

The stump feet form very small to medium-sized agaric mushrooms with a sidewalk to shell-shaped shape with predominantly white to light brown shades. The stalk has grown on the side of the hat , rudimentarily stunted or missing completely. The lamellas are rounded or run down the stem, have a whitish color and take on pink, clay or gray-brown tints with age. The spore powder is ocher to pink brown or pale cinnamon brown. There is no velum . In the meat a gelatinous layer is sometimes available.

Microscopic features

Buckles may be present or absent on the septa of the hyphae . The lamella trama has a regular to almost regular structure. There are hair-shaped or club-shaped cystids on the cutting edges, none are found on the lamellar surfaces . The basidia are mostly 4-spore, less often 2-spore. The pale brown spores are spherical to elliptical or almond-shaped and have no germ pore. The spore wall is ornamented either smooth, warty or spiky.

ecology

The stump feet are saprobiontic inhabitants of wood and other plant residues, mosses or, more rarely, on the ground.

species

The worldwide common genus contains about 200 species. There are around 30 taxa in Europe  or can be expected there.
