New species and a new record of Phylloporia from Benin
Abstract Species of the wood-decay genus Phylloporia (Hymenochaetaceae, Hymenochaetales, Basidiomycota) are widely distributed in the tropics. Phylloporia species are, however, morphologically and ecologically diverse, which makes morphology-based species identification challenging. In this study, w...

| Sumario: | Abstract Species of the wood-decay genus Phylloporia (Hymenochaetaceae, Hymenochaetales, Basidiomycota) are widely distributed in the tropics. Phylloporia species are, however, morphologically and ecologically diverse, which makes morphology-based species identification challenging. In this study, we re-examined species of Phylloporia reported from Benin (West Africa). Using an integrative approach combining morphology, ecology, and phylogenetic analyses, we describe Phylloporia beninensis sp. nov. and report Phylloporia littoralis for the first time outside of its type locality. Phylloporia beninensis sp. nov. is characterized by its annual and imbricate basidiomata, duplex context with a black zone separating the upper context from the lower one, dimitic hyphal system, presence of cystidioles, basidia of 9–12 × 4–5 μm, and subglobose to ellipsoid basidiospores measuring 3–4.6 × 2.1–3.6 μm. Detailed descriptions with illustrations for the new species are provided. With the addition of the new species, 15 Phylloporia species are now known to occur in tropical Africa. Our discovery of a new Phylloporia species in Benin should stimulate further mycological investigations in tropical African ecosystems to discover other new polypore species. To facilitate further taxonomy studies on tropical African Phylloporia taxa, a key to the known tropical African species is provided. |
