Starfire blackhead The young fruit body is spherical, pear-shaped or bulbous, 4-7 cm in size, with a sharp nose up to 2 cm long, color from white to brown. Exoperidium (outer shell) fused with endoperidium (inner shell). An important sign is the destruction of endoperidium during maturation, as a result of which the gleb is completely exposed. It can develop both on the ground and partially protruding above the surface. When ripe, the outer shell is stellarly torn into 4-6 (5-7) blades (there are data on 14 blades), spread out on the soil or raising a spherical glebe above the ground.

Just like the giant raincoat, it can be classified as a 'meteor' species.

The pulp is initially dense, consisting of capillation and spores, as it ripens weakly fibrous, powdery, dark brown. Capillium (thin fibers) helps to loosen the spore mass, and its hygroscopicity causes movement and promotes dispersion of spores.

Habitat The fungus grows on humus soils in deciduous forests, forest belts of maple, ash, gleditsia, forest parks, gardens. It is found not too often or even rarely, rather, in areas with a warm climate, in rare deciduous groves, parks and gardens, less often in coniferous forests. Found in the forests of Europe, as well as in the mountain forests of Central Asia. It is noted that this species is not distributed far to the north. In Western Europe, it is known only in Hungary, Germany, Austria, Switzerland. In the European part of Russia it enters the north no further than the Moscow region. The species is rare.

SIMILAR SPECIES Due to its large size, bare, shaggy ball of the fertile part, which, when ripe, is not covered with an inner layer of the shell, the black-headed earthen star cannot be confused with other types of earthen stars.
