Extract from Wikipedia article: Geastrum quadrifidum, commonly known as the rayed earthstar or four-footed earthstar, is an inedible species of mushroom belonging to the genus Geastrum, or earthstar fungi. First described scientifically by Christian Hendrik Persoon in 1794, G. quadrifidum is a cosmopolitan—but not common—species of Europe, the Americas, Africa, Asia, and Australasia. The fungus is a saprobe, feeding off decomposing organic matter present in the soil and litter of coniferous forests.
Geastrum quadrifidum is a species of earthstar fungus characterized by its four-armed, star-shaped fruiting body with a central rounded sporocarp. In St. Petersburg and Leningrad Oblast, it typically grows in moist, sandy soils and coniferous forests. Records from north-western Russia indicate that Geastrum quadrifidum fruits from July to October, often in association with pine, spruce, or birch trees. The fungus is considered rare in the region, but can be found in protected areas and nature reserves, such as the Karelian Isthmus and the Vepsian forest zone.
