Abstract

Armillaria root rot has been known to occur on economically important Pinus and Eucalyptus species grown in plantations in South Africa since the early 1900s. Armillaria species have been well studied in North America and Europe, but have received minimal attention in South Africa. Most reports of Armillaria root rot in South Africa suggest that A. mellea (Vahl.:Fr.) P. Kumm. is the causal agent. The name A. heimii Pegler has also been used in more recent reports, although these have not been based on mycological studies. The taxonomic disposition of Armillaria in South Africa, therefore, remains unknown. The aim of this study was to identify and characterise Armillaria isolates from forest plantations in South Africa based on morphological data, PCR-RFLP profiles and sequence data. Analysis of these characters revealed that the isolates originating from the plantations in South Africa are distinct from A. mellea and A. heimii. We believe that they represent A. fuscipes Petch.
