¿Cuáles son las especies de Laetiporus presentes en el sur de América del Sur?

Abstract

The identity and phylogenetic relationships of Laetiporaceae taxa (Polyporales, Basidiomycota) remain poorly studied. In this work we carry out a multigene phylogenetic analysis to identify the Laetiporus species that grow in South America and move forward the understanding of the phylogenetic relationships among the poroid genera of Laetiporaceae within the antrodia clade. Based on the morphology and molecular phylogenetic data, two new genera are proposed, Berckurtia to accommodate Berkcurtia persicina comb. nov. and Atlantiporus to accommodate Atlantiporus squalidus comb. nov., and 2 other new combinations Kusaghiporia talpae and Laetiporus dilatohyphus. A key to the poroid genera of the Laetiporaceae is also provided and the taxonomic implications for these species and related taxa are discussed.
