A fungal strain was isolated from surface-sterilized roots of Rhododendron mucronulatum, a plant species belonging to the Ericaceae family, collected from Mt. Minjujisan, Korea. This fungal strain was identified as Rhizodermea veluwensis based on its morphological characteristics and based on phylogenetic analysis of its internal transcribed spacer regions and large-subunit rDNA. R. veluwensis has not been previously reported in Korea, and for the first time, we report and describe it herein.
