pentaprisma

Pentaprisma is a genus of fungi belonging to the family Tricholomataceae. These mushrooms are characterized by their distinctive five-sided prisms that form the gills on the underside of the cap. The shape of these gills is a key feature used in identification. The caps of Pentaprisma species are typically convex to flat, and their color can vary, often ranging from white to pale brown or grey. The stems are usually slender and central. Pentaprisma species are generally found growing on the ground or on decaying wood in woodland environments. Their distribution is primarily in temperate regions. Information regarding their edibility is often limited or uncertain, and it is generally advised to avoid consuming wild mushrooms unless positively identified by an expert. Research into the specific ecological roles and life cycles of Pentaprisma species is ongoing. The genus was first described in the late 20th century, with subsequent taxonomic studies refining its classification within the broader fungal kingdom. Further mycological research aims to better understand the genetic relationships and evolutionary history of this genus.
