Tricholosporum goniospermum
Tricholosporum goniospermum is a species of fungus in the family Tricholomataceae, and the type species of the genus "Tricholosporum". First described scientifically by Giacomo Bresadola in 1881 as "Tricholoma goniospermum", it was transferred to the genus "Tricholosporum", established in 1975 by Mexican mycologist Gaston Guzman. As was pointed out in a 1982 publication by Tim Baroni, the transfer was not valid, "because complete reference to the authors and the original publications of the basionyms was not provided". Baroni made the new combination official in his publication.
