 Inocybe praetervisa is a small , yellow and brown mushroom in the <unk> family , distinguished from other members of the genus by its unusual spores and bulb . The unusual spores led to the species being named the type species of the now @-@ abandoned genus Astrosporina ; recent studies have shown that such a genus could not exist , as the species with the defining traits do not form a monophyletic group . However , it is a part of several clades within the genus Inocybe . I. praetervisa grows on the ground in woodland , favouring beech trees , and can be found in Europe , North America and Asia . It is inedible and probably poisonous due to the presence of muscarine . The ingestion of muscarine can lead to <unk> syndrome , and could potentially lead to death due to respiratory failure .
