Tulostoma

Tulostoma is a genus of fungi in the order Agaricales, commonly known as stalked puffballs. Species produce conspicuously stalked fruiting bodies bearing a globose to ovoid gleba-bearing head on the top of a slender stalk. The peridium encloses a spore mass (gleba) that is initially white or pale and darkens to brown as spores mature. The stalk is typically rigid and can be several centimeters to decimeters tall, elevating the gleba above the substrate to facilitate spore dispersal.

Tulostoma is placed in the family Tulostomataceae, though some classifications place the genus within Agaricaceae. The genus includes multiple dozen species with a cosmopolitan distribution, prevalent in tropical and temperate regions and often found on soil, leaf litter, or decaying wood, including disturbed habitats.

Ecology: Tulostoma species are saprotrophic, feeding on decaying plant material. Fruiting generally occurs after rainfall or in humid conditions, sometimes during warm, dry seasons depending on species.

Reproduction: Spores are produced in the gleba inside the top portion. When mature, spores are dispersed by air currents; rainfall can also cause rupture of the gleba and release.

Edibility: Most Tulostoma species are not considered edible due to texture and small size; several are regarded as inedible or of unknown culinary value. As with puffballs, accurate identification is important to avoid confusion with toxic forms.
