Ceratocystis and Ophiostoma species including three new taxa, associated with wounds on native South African trees
Fungal Diversity 29, 37-59
Abstract: Fungal species in Ceratocystis and Ophiostoma include important pathogens, associated with insects that typically infect wounds visited or made by their vectors. There are few reports of these fungi from the African continent and little is known regarding their relative importance in the area. In this study, species of Ceratocystis and Ophiostoma were collected from wounds on native tree species in selected areas of South Africa and they were identified based on morphological and DNA sequence comparisons. Ceratocystis and Ophiostoma species were collected from eight different native trees including six different families. These included Ophiostoma quercus, Pesotum fragrans, Ceratocystis albifundus as well as an undescribed Ophiostoma sp. and two undescribed Ceratocystis spp. The new Ceratocystis spp. are described here as Ceratocystis savannae sp. nov. and Ceratocystis tsitsikammensis sp. nov. and the Ophiostoma sp. as Ophiostoma longiconidiatum sp. nov. In pathogenicity tests, C. tsitsikammensis sp. nov. resulted in significant lesions on Rapanea melanophloeos trees, while C. savannae sp. nov. produced very small lesions on Acacia nigrescens and Sclerocarya birrea trees.
