Perenniporiella gen. nov. segregated from Perenniporia, including a key to neotropical Perenniporia species with pileate basidiomes.

Perenniporiella gen. nov. is segregated from Perenniporia. The new combinations Perenniporiella neofulva and Perenniporiella micropora, and the new species Perenniporiella pendula are proposed. Perenniporia piperis and Perenniporia albida are considered as taxonomic synonyms of P. neofulva. The three species are described and their taxonomic position is discussed. A key to the neotropical Perenniporiella and Perenniporia species with pileate basidiomes is presented.
