Telimena (Telimenaceae, Phyllachorales) species on Neotropical host plants: New species, combinations and revision of species on Polygonaceae

Abstract

In this investigation, we propose a new species in Telimena, T. bromeliae sp. nov. growing on bromeliads with a detailed description, illustrations, and molecular characterisation based on material collected in Costa Rica and Panama. Additionally, four species of Phyllachora occurring on non-graminicolous hosts are transferred into Telimena based on morphological and molecular data: T. amphibola comb. nov. on Inga spp. and T. tenuis comb. nov. on Bauhinia spp. (Fabaceae, Cercidiodeae); T. dominicana comb. nov. on Coccoloba spp.; and T. rubefaciens comb. nov. on Clethra spp. (Clethraceae). The species with newly combined names are redescribed and fully illustrated from type specimens and material recently collected in Costa Rica, Florida (USA) and Panama. Additionally, a revision of tropical tar spot fungi on host species belonging to the family Polygonaceae is provided, including a dichotomous key of known species and geographical distribution data.
