A preliminary survey of the soil mycoflora of an acacia Karroo community in Potchefstroom with a description of a new species

Abstract

A preliminary survey of the mycoflora of an Acacia karroo community in the vicinity of Potchefstroom, was made. Only the leaf litter and first inch of soil were investigated. Two different methods were employed for the isolation of the fungi, viz. the dilution method as modified by Menzies (1957) and the soil plate method of Warcup as devised by Johnson and Manka. (1961) Seven hundred and twenty six pure culture isolations were made and 3 79 of these were identified. The identified specimens included 49 Zygomycetes, 323 Fungi lmperfecti and 7 Ascomycetes . Several of the specimens were found to be new and undescribed species with 4 representing new genera. One of the new species 1s described as Sympodina simplex.
