Phylloporus and Phylloboletellus are no longer alone: Phylloporopsis gen. nov. (Boletaceae), a new smooth-spored lamellate genus to accommodate the American species Phylloporus boletinoides.

ABSTRACT: The monotypic genus Phylloporopsis is described as new to science based on Phylloporus boletinoides. This species occurs widely in eastern North America and Central America. It is reported for the first time from a neotropical montane pine woodland in the Dominican Republic. The confirmation of this newly recognised monophyletic genus is supported and molecularly confirmed by phylogenetic inference based on multiple loci (ITS, 28S, TEF1-?, and RPB1). A detailed morphological description of P. boletinoides from the Dominican Republic and Florida (USA) is provided along with colour images of fresh basidiomata in habitat, line drawings of the main anatomical features, transmitted light microscopic images of anatomical features and scanning electron microscope images of basidiospores. The taxonomic placement, ecological requirements and distribution patterns of P. boletinoides are reviewed and the relationships with phylogenetically related or morphologically similar lamellate and boletoid taxa such as Phylloporus, Phylloboletellus, Phyllobolites and Bothia are discussed.
