Piziza

Piziza is a genus of fungi belonging to the family Pyronemataceae. These fungi are typically cup-shaped or saucer-shaped, with a relatively small size, often less than a centimeter in diameter. The outer surface of the cup may be smooth or slightly hairy. Piziza species are saprobic, meaning they obtain nutrients by decomposing dead organic matter, commonly found on soil, dung, or decaying plant material. Their ascocarps, or fruiting bodies, often emerge after periods of rain, particularly in moist environments.

The taxonomy of Piziza has undergone revisions, and its classification within the Pyronemataceae reflects its evolutionary relationships with other related fungal genera. Identification of specific Piziza species can be challenging and often relies on microscopic examination of their ascospores and asci. Ascospores are typically smooth and ellipsoid. While not generally considered edible or of significant economic importance, Piziza plays a role in nutrient cycling within its ecosystem. Some species have been studied for their potential in various ecological processes, though widespread cultivation or use is uncommon. The genus is distributed globally, with different species adapted to various climatic conditions and habitats.
