Abstract

Nineteen strains of Trametes species were collected from the area of Kangwon Province, Korea. They have a variety of color hands and line-up markings on fruit bodies. Most strains were categorized into four types based on color bands, that is, dark brown, light brown, dark gray and light gray. They also have line-up marking shapes from sparse to compact on fruit bodies. In this study, we tried to investigate the relationship between the genetic variation and morphological appearance of these species using the nuclear ribosomal ITS1-5.8S-ITS2 region sequence, we used nineteen strains collected in nature and four species of five standard strains (T. versicolor KCTC16781, KCTC26203, T. villosa KCTC06866, T. suaveolens KCTC26205 and T. hirusta KCTC26200). The data of ITS sequences indicated that nineteen strains of T. versicolor have the difference of $1{\sim}6$ base pairs, comparing with standard strains of T. versicolor KCTC16781, and KCTC26203. Phylogenetic analysis of the Trametes species showed that they grouped into a wide range of single clade. Standard strains except T. versicolor KCTC16781 and KCTC26203, formed separated subgroup.
