On Neotropical Fuscoporia with strigose pileus surface: Redescription and phylogenetic study of Polyporus sarcites and a new species Fuscoporia dollingeri (Hymenochaetaceae, Basidiomycota)

Abstract

Specimens of poroid Hymenochaetaceae with uniquely strigose pileus surfaces were collected and studied morphologically and phylogenetically (using as markers ITS and nrLSU ribosomal DNA). Detailed morphological examination showed that the specimens belong to two distinct species of Fuscoporia. Fuscoporia sarcites comb. nov., which is proposed and recorded for the first time in Guatemala, Honduras, and Venezuela, and the newly described Fuscoporia dollingeri sp. nov., which was collected several times in Florida (USA). Morphological and ecological data of these species are compared to other similar species, and an identification key of Neotropical Fuscoporia is provided.
