- Abstract
Armillaria heimii is one of the most widespread Armillaria species recorded in Africa. The species was originally described as Clitocyhe (Armillariella) elegans Heim, and was renamed as Armillaria heimii Pegler; this name was subsequently made synonymous with A. fuscipes Petch to represent as a single morphological species. Recent molecular work has suggested that isolates previously identified as A. heimii were distinct and may represent A. fuscipes or another Armillaria species. A collection of isolates that had been identified as A. heimii from different African countries were included in an integrated study that included amplified restriction-length polymorphism (AFLP) fingerprinting, polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP), sequencing, induction of hasidiomata in vitro and somatic compatibility, in order to determine their identity. Although the isolates could he assigned to one of two molecular groups, the morphology and somatic compatibility characters suggested that the two groups represent different forms of a single species that closely matches the original description of A. heimii.
