Tulostoma is a genus of over 100 species of fungi in the family Agaricaceae. Commonly known as stalked puffballs, the cosmopolitan genus consists of species which produce small fruit bodies, characterized by stalks inserted in a socket at the base of the spherical spore-sac opened by a small and apical mouth. The spore-sac contains gleba, a mixture of spores and associated cells; at maturity, the spores are released through one or more apical pores. Tulostoma species prefer xeric microhabitats, savannahs and deserts, and are saprobic—obtaining nutrients by decomposing roots, buried wood and other organic material of plant origin.
