Abstract

A unrecorded species of Trichocladium, Trichocladium griseum, was isolated in 2017 during a survey of fungal diversity in Ulsan province, South Korea. This species was identified based on morphological characteristics and phylogenetic analysis of the internal transcribed spacer (ITS) rDNA and β-tubulin gene sequences. T. griseum has not yet been reported in South Korea. Thus, we report for the first time a new record of Trichocladium griseum in Korea, and we include the descriptions and morphological illustrations of this fungus.

Figures & Tables

Fig. 1. Phylogenetic tree based on neighbor-joining analysis of the internal transcribed rDNA sequence obtained from EML-KNU17-5. Microascus trigonosporus was used as outgroup. Bootstrap scores of 60% are indicated at the nodes. The scale bar represents the number of substitutions per site. The new isolate described in this study is shown in bold.
