title: Phellinus caribaeo-quercicolus sp. nov., parasitic on Quercus cubana: taxonomy and preliminary phylogenetic relationships.
abstract: Phellinus caribaeo-quercicolus sp. nov. is described from several collections made in western Cuba, so far exclusively on Quercus cubana. The species is characterized by a perennial, resupinate basidiomes, cushion-shaped to nodulose and multi-layered when old, apically hooked to hamate hymenial setae, and ellipsoid to broadly ellipsoid, thin- to thick-walled, hyaline to faintly yellowish basidiospores, 4.5-5.5 x 3.5-4.5 microm. The species is compared to other Phellinus species with hooked setae, especially Phellinus undulatus, also recorded in Cuba. The preliminary phylogenetic relationships of Ph. caribaeo-quercicolus within the poroid Hymenochaetales complex of genera is presented and discussed here.
