Molecular Taxonomy of Ganoderma cupreum from Southern India Inferred from ITS rDNA Sequences Analysis

Abstract Ganoderma is a cosmopolitan wood-rot basidiomycete that has been extensively studied for its pathogencity and medicinal properties. Identification of Ganoderma based on macro-microscopic features led to large number of synonyms which resulted in 250 taxonomic names. A Ganoderma species collected from Courtallam, Tamil Nadu was identified as G. cupreum. Phylogenetic analysis inferred from internal transcribed spacer rDNA region resolved the Indian isolate MYC1 as Ganoderma cupreum which clustered with Australian and Asian “cupreum ” clade with 85 % bootstrap support BS and shared 99 % and 98% nucleotide similarity with Malaysian and Australian ‘cupreum ’ respectively. This study represents the first molecular evidence of G. cupreum from Asian origin
