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

The monotypic genus is described as new to science based on 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, and ). A detailed morphological description of 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 are reviewed and the relationships with phylogenetically related or morphologically similar lamellate and boletoid taxa such as , , and are discussed.
