Extract from Wikipedia article: Coprinellus angulatus is a species of mushroom in the family Psathyrellaceae. First described by mycologist Charles Horton Peck in 1874 and placed in the genus Coprinus, a 2001 phylogenetic study resulted in a major reorganization and reshuffling of that genus, and this species was transferred to Coprinellus.
Coprinellus angulatus is a small to medium-sized fungus with a bell-shaped cap that measures 1-4 cm in diameter, typically grayish-brown to dark brown in color with a distinctive angular or rib-like pattern of fine lines or wrinkles on the cap surface. The gills are crowded, free from the stem, and initially pale gray, turning black as the spores mature. The stem is slender, hollow, and usually shorter than the cap diameter. In East and Central Texas, Coprinellus angulatus can be found growing in clusters or scattered on rich soil, decaying wood, or dung, often in shaded areas with abundant organic matter, from spring to fall, particularly after rainfall.

AI-generated summary of observations
Observations of Coprinellus angulatus in East and Central Texas reveal that the fungus thrives in areas with disturbed soil, particularly where fires have occurred. On Caney Creek Trail in Sam Houston National Forest, the mushrooms were found growing on a bonfire site, with multiple observations recorded on March 11, 2020. The mushrooms grew in groups, with compact clusters and individual specimens displaying characteristic gills. Similar findings were made on a utility line cutting on Lone Star Hiking Trail on March 23, 2020. In Bastrop State Park, the fungus was observed growing in areas of recent prescribed burns, with young and mature specimens found in tight clusters on burnt ground between March 24, 2020. The species often co-occurred with other fungi, such as small Tephrocybe.
