NOTE] Two Novel Talaromyces Species Isolated from Medicinal Crops in Korea: Hyunkyu Sang , Tae-Jin An , Chang Sun Kim , Gyu-Sub Shin , Gi-Ho Sung , Seung Hun Yu; J. Microbiol. 2013;51(5):704-708. Published online October 31, 2013; DOI: https://doi.org/10.1007/s12275-013-3361-9

Abstract: Two novel biverticillate Talaromyces species, T. angelicus and T. cnidii, were collected from the medicinal crops Angelica gigas and Cnidium officinale, respectively, in Korea. Phylogenetic analyses with the nuclear ribosomal internal transcribed spacer (ITS) region and the β-tubulin gene as well as morphological analyses revealed that the two species differ from any known Talaromyces species. Talaromyces angelicus is related to T. flavovirens in the phylogeny of the ITS region, but the new species is grouped together with Penicillium liani and T. pinophilus in terms of its β-tubulin phylogeny, and its growth rate on Czapek yeast autolysate differs from that of T. flavovirens. Talaromyces cnidii is phylogenetically similar to T. siamensis, but exhibits differences in the morphologies of the colony margin, metulae, and conidia.

NOTE] Penicillium daejeonium sp. nov., a New Species Isolated from a Grape and Schisandra Fruit in Korea: Hyunkyu Sang , Tae-Jin An , Chang Sun Kim , Young Phil Choi , Jian-Xin Deng , Narayan Chandra Paul , Gi-Ho Sung , Seung Hun Yu; J. Microbiol. 2013;51(4):536-539. Published online August 30, 2013; DOI: https://doi.org/10.1007/s12275-013-3291-6

Abstract: Two isolates of monoverticillate Penicillium species were collected from a grape and schisandra fruit in Korea. Multigene phylogenetic analyses with the nuclear ribosomal internal transcribed spacer (ITS) region and genes encoding β-tubulin (benA) and calmodulin (cmd), as well as morphological analyses revealed that the two isolates are members of the P. sclerotiorum complex in Penicillium subgenus Aspergilloides, but different from species of the P. sclerotiorum complex. The isolates are closely related to P. cainii, P. jacksonii, and P. viticola in terms of their multigene phylogeny, but their colony and conidiophore morphologies differ from those of closely related species. The name P. daejeonium is proposed for this unclassified new species belonging to the P. sclerotiorum complex in subgenus Aspergilloides.
