Resumo: 	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 nrDNA phylogeny, they formed two distinct groups, one of which was closely related to Helotiales (Leotiomycetes). The new genus Collophora is proposed, comprising five species that frequently occur in necrotic peach and nectarine wood, namely Co. africana, Co. capensis, Co. paarla, Co. pallida and Co. rubra. The second group was closely related to Phaeomoniella chlamydospora (Eurotiomycetes), occurring mainly in plum wood. Besides P. zymoides occurring on Prunus salicina, four new species are described, namely P. dura, P. effusa, P. prunicola and P. tardicola. In a preliminary inoculation study, pathogenicity was confirmed for some of the new species on apricot, peach or plum wood.
