Identification of Armillaria in South Africa
Phytopathology 86 (11 suppl.), S102-S102
Abstract: Armillaria spp. are important pathogens of trees throughout the world. The genus has been well studied in North America and Europe, but has received minimal attention in Africa. Armillaria mellea was first reported to occur in South Africa in the early 1900's, associated with root rot of Pinus and Eucalyptus. The taxonomic disposition of the fungus, however, remains doubtful although the name A. heimii has recently been used in some reports. The aim of this study was to examine isolates of Armillaria from Southern Africa. Thirty one isolates, originating from different regions in Southern Africa, were obtained using established isolation techniques. These were compared using cultural morphology, basidiomes produced in vitro and on the basis of RFLP's. Our preliminary results suggest that at least two species of Armillaria occur in South Africa.
