Untangling the Central African Cantharellus Sect. Tenues: Cantharellus minutissimus sp. nov. and Epitypification of Cantharellus alboroseus.

Cantharellus section Tenues was originally created for four new, very small, redorange-yellow Central African chanterelles with a more or less fistulose stipe, short basidia and an omphaloid habit. The type species, C. tenuis, is here considered unrelated to the other three species as it is the only species having clamp connections. All four species remain poorly known and need to be recollected and epitypified with recently collected, sequenced specimens that comply to the original description. In this paper, C. alboroseus is epitypified, and an equally small species, C. minutissimus, is introduced. Both species are systematically placed using a multigene phylogeny. [ABSTRACT FROM AUTHOR]
