Taxonomy
The genus was first described by American mycologist
William Alphonso Murrill
William Alphonso Murrill (October 13, 1869 – December 25, 1957) was an American mycologist, known for his contributions to the knowledge of the Agaricales and Polyporaceae. In 1904, he became the assistant Curator at the New York Botanical Ga ...
in 1909.

Murrill set ''Pulveroboletus ravenelii'' as the
type species
