Panellus pusillus

About

Panellus pusillus is a species of fungus in the family Mycenaceae. A widely distributed species, it has been recorded in Australia, Asia, Europe, North America, and South America. The fungus was first given its current name in 1975, but has been known by many names since French physician and mycologist Joseph-Henri Léveillé first described it as Gloeoporus pusillus in 1844. A recent molecular phylogenetic study explored the diversity and phylogeny of Panellus, and used species like P. pusillus to identify five new poroid species from China in the genus.
