Extract from Wikipedia article: Gyromitra gigas, commonly known as the snow morel, snow false morel, calf brain, or bull nose, is a fungus and a member of the Ascomycota. G. gigas is found in Europe. It is referred to as one of the false morels, due to its similar appearance and occurrence in the spring and early summer in similar habitats to true morels (Morchella ssp.). It is edible if properly prepared but should be avoided due to variability and similarity to other more toxic species of Gyromitra. A similar species, Gyromitra montana occurs in North America.
Gyromitra gigas is a species of ascomycete fungus characterized by its large, brain-like cap, typically 4-10 cm in diameter, with wavy or lobed margins. In St. Petersburg and Leningrad Oblast, it fruits from May to July, often in association with coniferous trees, particularly spruce and pine. In north-western Russia, Gyromitra gigas is commonly found in moist, shaded areas with rich soil, including forests, woodlands, and river valleys. The fungus contains gyromitrin, a toxic compound that can cause poisoning if ingested raw or improperly prepared.
