Phaeosperma

Phaeosperma is a genus of fungi belonging to the order Sclerodermatales. These fungi are commonly known as false truffles due to their morphological similarities to true truffles. Phaeosperma species are typically found in terrestrial habitats, often associated with ectomycorrhizal associations with trees. Their fruiting bodies, or sporocarps, are generally subterranean or partially exposed, and vary in size and shape depending on the species. The internal structure of the sporocarp typically consists of a peridium, or outer skin, and a gleba, which contains the spore-producing tissues.

The spores of Phaeosperma are notable for their dark coloration and often spiny or reticulate ornamentation. These characteristics are important for taxonomic identification. The genus Phaeosperma is distinguished from other related genera within the Sclerodermatales by specific microscopic features of the spores and basidia, as well as differences in the structure of the peridium. Research into the ecological role of Phaeosperma species suggests they play a part in nutrient cycling and soil health through their mycorrhizal relationships. Distribution of Phaeosperma species is global, with various species found across different continents, often in temperate and tropical forests. Further research continues to refine the taxonomy and understanding of the ecological significance of this genus.
