Abstract

Two new species of Gymnopus (G. atlanticus and G. talisiae) from Northeast Brazil and the neotropical G. montagnei are described, illustrated and treated here under a polyphasic taxonomical perspective. According to our phylogenetic analyses (ITS rDNA), sequences of these three species grouped with other taxa of Gymnopus sect. Impudicae, forming a well-supported monophyletic clade. These results confirm the placement of the treated species within Gymnopus sect. Impudicae, as well as suggesting that this section represents a natural and monophyletic group, with its morphological limits, however, in a need of re-evaluation.
