Abstract

The symbiosis between <i>Armillaria</i> species and an achlorophylous orchid <i>Gastrodia elata</i> B<small>LUME</small> has been reported. The main species described as a symbiont is <i>Armillaria mellea</i> (V<small>AHL</small>: F<small>R</small>.) K<small>UMMER</small>, known widely as a primary root rot pathogen. Samples collected from the rhizomorphs attached to the tuber of <i>G. elata</i> were separated and analyzed. Molecular analysis based on sequencing of the intergenic spacer 1 (IGS-1) and internal transcribed spacer (ITS) regions of the ribosomal DNA (rDNA) was performed, coupled with restriction fragment length polymorphism (RFLP) of the IGS-1 region. Cultural morphology and features of basidiomata were also used to characterize the isolates. Phylogenetic analysis and morphological data strongly suggested that the fungus present in the tubers of <i>G. elata</i> is <i>Armillaria nabsnona</i>. This is the first report of occurrence of this <i>Armillaria</i> species in association with <i>G. elata</i>.
