Gyromitra gigas

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 contains small quantities of hydrazines,[5] its content in gyromitrin was scientifically assess by Viernstein et al. [Botanical identification 1980] and resulted of about 1mg per kg of fresh mushroom (roughly 1500 fold less compared to esculenta). No casualties have been ascribed to its consumption, parboiling is still highly recommended. Some guides have listed it as being edible if properly prepared. However, consumption is not recommended due to variability and similarity to other more toxic species of Gyromitra.[6] A similar species, Gyromitra montana occurs in North America.
