Extract from Wikipedia article: Parasola auricoma is a species of agaric fungus in the family Psathyrellaceae. First described scientifically in 1886, the species is found in Europe, Japan, and North America. The mushroom was reported in February 2019 in Colombia, in the city of Bogota by the mycologist Juan Camilo Rodriguez Martinez. The small, umbrella-shaped fruit bodies (mushrooms) of the fungus grow in grass or woodchips and are short-lived, usually collapsing with age in a few hours. The caps are up to 6 cm (2.4 in) wide, initially elliptical before flattening out, and colored reddish-brown to greyish, depending on their age and hydration. They are pleated with radial grooves extending from the center to the edge of the cap. The slender, whitish stems are up to 12 cm (4.7 in) long and a few millimeters thick. Microscopically, P. auricoma is characterized by the presence of setae (thick-walled bristles) in its cap cuticle. This characteristic, in addition to the relatively large, ellipsoid spores can be used to distinguish it from other morphologically similar Parasola species.
Swedish: Brunhårig bläcksvamp.
Parasola auricoma is a small to medium-sized fungus with a bell-shaped cap, typically 1-3 cm in diameter, featuring a golden-brown to yellowish-brown color with a fibrillose or scaly surface. The gills are crowded and free from the stem. It grows in fields, meadows, and along roadsides, often in grassy areas. In East and Central Texas, Parasola auricoma has been found fruiting from spring to fall, particularly after rainfall, with a preference for rich soil and full sun to partial shade.

Inkcap mushrooms Parasola auricoma(?) in Lick Creek Park. College Station, Texas, September 27, 2024Yaupon Loop Trail, College Station, Brazos County, Texas, United StatesObservations of the fungus Parasola auricoma in East and Central Texas reveal its presence in various locations, including Lick Creek Park, Wolf Pen Creek Park, Bee Creek Park, and Washington-on-the-Brazos State Historic Site. The mushrooms were found growing on lawns, in mulch, and on dry grass in forest clearings. They were observed during different months, including May, June, April, and September, indicating a potentially long fruiting season. The mushrooms' caps and undersides were documented, as well as their spores under a microscope using KOH. Some observations noted the possibility of other species, but most confirmed Parasola auricoma. The fungus appears to thrive in a range of environments, from urban parks to natural areas, in East and Central Texas. Repeat sightings in Lick Creek Park suggest a established presence in this location.
