Prosvirina

Prosvirina is a genus of fungi belonging to the family Psathyrellaceae. These fungi are characterized by their small to medium-sized fruiting bodies, which are typically fragile and often found growing on decaying wood or other organic matter. The cap of Prosvirina species can vary in color and shape, often exhibiting hygrophanous properties, meaning they change color as they dry out. The gills are usually attached to the stem and can be white, gray, or brown. The spore print is typically dark brown to black.

The genus Prosvirina was first described in the early 21st century, and research is ongoing to fully understand its taxonomic placement and the diversity within the group. Many species were previously classified under other genera, such as Psathyrella, before being re-evaluated based on morphological and molecular data. The ecological role of Prosvirina species primarily involves decomposition, contributing to nutrient cycling in forest ecosystems. Their distribution is widespread, with various species found across different continents. Identification of Prosvirina can sometimes be challenging due to the subtle differences between species and their resemblance to other small brown mushrooms. Further research is needed to fully document the species richness and distribution of this genus.
