Poroid Hymenochaetaceae associated with trees showing wood-rot symptoms in the Garden Route National Park of South Africa

ABSTRACT

Poroid Hymenochaetaceae associated with wood rots of trees in three timber-harvesting compartments of the Garden Route National Park (GRNP), South Africa, were investigated using multilocus phylogenetic analyses and morphology of the basidiomes. Results revealed the presence of 10 species belonging to five genera. Six of the species are known, but four are described as new. The known species include Fomitiporia capensis, Fuscoporia gilva, Sanghuangporus microcystideus, Tropicoporus tropicalis, Inonotus rickii, and Inonotus setuloso-croceus. The new species are described as Fomitiporia tsitsikamensis, Fulvifomes elaeodendri, Fuscoporia pulviniformis, and Phellinus guttiformis.
