Taxonomy and phylogeny of Heterobasidion in South Korea

ITS and TEF gene sequences from eleven basidiome collections from South Korea and one mycelial culture were analyzed to infer the phylogeny of Korean Heterobasidion species. Comparison of morphological characters with phylogenetic analyses revealed that specimens previously recorded as 'H. annosum' and 'H. araucariae' in fact represent H. ecrustosum, while those recorded as 'H. insulare' represent H. orientale. The two species currently recognized in South Korea are described and illustrated.
