Favolaschia in remnants of the Atlantic Forest, Brazil

•Favolaschia luteaurantiaca is proposed as a new species.•Favolaschia cinnabarina is confirmed within subsection Auriscalpium clade.•A better molecular phylogeny for Favolaschia was revealed.

The examination of recent collections of Favolaschia from remnants of the Atlantic Forest, Brazil, resulted in the identification of F. aurantiaca, F. cinnabarina and F. luteoaurantiaca sp. nov. Internal transcribed spacer (ITS) sequences obtained from these collections were introduced into the previously published phylogenetic tree of the genus to assess the position of these species within the Favolaschia clade. A maximum likelihood analysis generated a phylogenetic tree with a better resolution, especially for the clade that contains species belonging to section Favolaschia subsection Auriscalpium, where the three specimens collected in Brazil also were clustered in.
