| Species of the genus Coniochaeta (anamorph: Lecythophora) are known as pathogens of woody hosts, but can also cause opportunistic human infections. Several fungi with conidial stages resembling Lecythophora were isolated from necrotic wood samples of Prunus trees in South Africa. In order to reveal their phylogenetic relationships, these fungi were studied on a morphological and molecular (5.8S nrDNA, ITS-1, ITS-2, GAPDH, EF-1α, 28S nrDNA, 18S nrDNA) basis. Some of the isolates were identified as Coniochaeta (Sordariomycetes), including C. velutina and two new species, C. africana and C. prunicola. The majority of the isolates, however, formed pycnidial or pseudopycnidial synanamorphs and were not closely related to Coniochaeta. According to their 28S... |

| Species of Encephalartos, commonly known as bread trees, bread palms or cycads are native to Africa; the genus encompasses more than 60 species and represents an important component of the indigenous African, flora. Recently, a leaf blight disease was noted on several E. altensteinii plants growing at the foot of Table Mountain, in the Kirstenbosch Botanical Gardens of South Africa. Preliminary isolations from dead and dying leaves of E. altensteinii,, E. lebomboensis and E. princeps, collected from South Africa, revealed the presence of several novel, microfungi on this host. Novelties include Phaeomoniella capensis, Saccharata kirstenboschensis, Teratosphaeria, altensteinii and T. encephalarti. New host records of species previously only known to occur... |
