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.
Parasola auricoma is a small to medium-sized fungus with a bell-shaped cap, typically 1-4 cm in diameter, yellowish-brown to reddish-brown in color, and a slender stem. It grows in fields, meadows, and along roadsides. In St. Petersburg and Leningrad Oblast, it has been found in urban and rural areas, often in nutrient-rich soils. In north-western Russia, it is considered a common species, fruiting from July to October, particularly in areas with moist soils and abundant organic matter.
