Taxonomic Study of the Genus Abundisporus in Korea

Abstract

The polypore genus Abundisporus Ryvarden is characterized by resupinate to pileate fruitbodies with a purplish brown hymenophore, slightly thick-walled, pale yellowish and non-dextrinoid basidiospores, and causing white rot. A purple color hymenophore, an easily observable and striking character, was considered the main distinctive feature at the generic level within polypores. However, due to highly similar basidiocarp features, species identification within these purple polypores is particularly difficult. Three species of purple colored polypores have been reported in Korea (Abundisporus fuscopurpureus, A. pubertatis, and Fomitopsis rosea). Based on morphological re-examination, ecological information, and sequence analysis of the internal transcribed spacer, we showed that previous classification was incorrect and there is only one species (A. pubertatis) in Korea. We provide a detailed description of A. pubertatis in Korea, as well as a taxonomic key to distinguish wood rot fungi with a purple hymenophore.

Three New Recorded Species of the Physalacriaceae on Ulleung Island, Korea

“…Although several coding genes have been used in recent fungal phylogeny studies, the ITS region remains the most commonly used locus for fungal phylogenetics, and the accumulated DNA sequence information for the ITS region has greatly improved the accuracy of identification in the Fungi [ 14 15 16 17 ]. Previously, we showed the efficiency and accuracy of a two-step approach for fungal identification: phylogenetic analysis using ITS sequences followed by confirmation based on morphological observations [ 18 19 20 21 ].…”

Seven New Recorded Species in Five Genera of the Strophariaceae in Korea

“…Accumulated DNA sequence information, in particular DNA barcoding using the ITS region, has greatly improved accuracy in identification of fungi at the species level and improved our understanding of fungal phylogenetic relationships [81213]. Specifically, many Asian species have been re-evaluated by molecular analysis, primarily using the ITS [141516]. …”

Five New Wood Decay Fungi (Polyporales and Hymenochaetales) in Korea

“…Wood decay fungi have traditionally been identified based on the morphology of their fruiting body as well as underlying microscopic features. Recently, the combination of these morphological data with ITS sequence analysis has increased the accuracy of species identification of wood decay fungi dramatically [25272829]. A recent project surveying and excavating Korean indigenous fungi has been organized by the National Institute of Biological Resources (NIBR, http://www.nibr.go.kr).…”
