Psathyrella longistriata, commonly known as the ringed brittlestem[1] or ringed psathyrella,[2] is a species of mushroom in the family Psathyrellaceae. It is found in the Pacific Northwest.[1]
Description
The cap of Psathyrella longistriata is about 1.7-5 centimeters in diameter. It starts out rounded and conical in shape, before becoming campanulate. Tissue from the partial veil sometimes hangs from the margins.[1] The margin of the cap is striated when moist.[3] These striations usually appear when the mushroom is older.[4] The cap also starts out fibrillose.[3] The stipe is about 3-9 centimeters long and 8-15 millimeters wide.[3] It also has an annulus, which is striated on the top.[3] The gills start out grayish buff in color, becoming darker and browner with age.[1] The spore print is dark purplish brown.[3]
Similar species
Psathyrella kauffmanii is similar, as it also has an annulus. It is found in eastern North America, as well as the American Southwest and the Rocky Mountains.[2] Psathyrella ellenae var. yubaensis also has an annulus, but it is smaller than P. longistriata and is not fibrillose. Its annulus and cap are also not striated.[3]
Habitat and ecology
Psathyrella longistriata is found in low-elevation forests, where it grows out of rotting wood or leaf litter. It mostly fruits during fall, but occasionally in winter and spring.[1]
