Psathyrella pennata, commonly known as the carbon brittlestem,[1] or bonfire brittlestem,[2] is a species of mushroom in the family Psathyrellaceae. It usually fruits during the spring.[1]

Description

The cap of Psathyrella pennata is brown, and starts out conical or egg-shaped, before expanding outward and becoming convex or flat. It is about 1.5-4 centimeters in diameter. When young, it is fibrillose. The stipe is about 3-7 centimeters long and 0.2-0.5 centimeters wide. It starts out fibrillose, becoming smoother as the mushroom gets older. When young, it has a faint ring zone from the partial veil. The gills are adnexed, and start out light brown, becoming darker with age.[1]

Habitat and ecology

Psathyrella pennata usually fruits during the spring, but it also sometimes does so in fall and winter.[1] It grows in soil in burned areas after forest fires[3][1] and at firepits.[2][1] It is often found near Morchella, Crassisporium funariophilum, and Geopyxis carbonaria, as well as other fungi.[3]
