Extract from Wikipedia article: Geastrum fimbriatum, commonly known as the fringed earthstar or the sessile earthstar, is an inedible species of mushroom belonging to the genus Geastrum, or earthstar fungi. First described in 1829, the species has a widespread distribution, and is found in Asia, Europe, and the Americas. It is distinguished from other earthstars by the delicate fibers that line the circular pore at the top of its spore sac.
Geastrum fimbriatum is an earthstar fungus characterized by its 4-8 cm diameter, spherical to cushion-shaped fruiting body with a persistent, felty exoperidium. In St. Petersburg and Leningrad Oblast, it typically grows in coniferous and mixed forests, often on sandy or podzolic soils. Records from north-western Russia indicate that Geastrum fimbriatum fruits from July to October, preferring moist, shaded areas with abundant leaf litter and moss cover. The species is considered rare in the region, but can be locally common in suitable habitats.
