A Novel Phaeoacremonium Species Isolated from Galls on the Chinese Magnolia-Vine (Schisandra chinensis) in Korea

초록

The fungal strain KNUF-24-9L1a, belonging to the genus Phaeoacremonium, was isolated from gall-midge (Lasioptera sp.; Diptera: Cecidomyiidae) larvae and their galleries on a Chinese magnolia-vine (Schisandra chinensis) sample collected in Mungyeong-si, Gyeongbuk province, Korea. Phylogenetic analyses based on concatenated nucleotide sequences of the beta-tubulin and actin genes revealed that the strain clustered with Phaeoacremonium species but occupied a distinct phylogenetic position. Morphological differences between strain KNUF-24-9L1a and closely related species were also observed. In this study, we provide detailed descriptions, illustrations, and discussions of the morphological and phylogenetic analyses of closely related species to support the novelty of this isolated species. The phylogenetic and morphological evidence suggests that strain KNUF-24-9L1a represents a novel species within the genus Phaeoacremonium, which we have designated this species as Phaeoacremonium schisandrae sp. nov.
