Taxonomy and phylogeny of Macrolepiota: two new species from Brazil

Mostrar todas las versiones(2)

Macrolepiota is a poorly known genus in the Neotropics. In order to increase knowledge about this group, we collected specimens from the Atlantic Forest in southern and northeastern Brazil. Macrolepiota cyanolamellata and M. sabulosa from subtropical and tropical regions, respectively, are proposed...
