Triangularia manubriata sp. Nov.: A Novel Fungal Species Belonging to the Family Podosporaceae Isolated from Soil in Korea

Mycobiology. 2024 Mar 22;52(2):111-116. doi: 10.1080/12298093.2024.2326240. eCollection 2024.

Abstract

The fungal strain designated as KNUF-21-020, belonging to the genus Triangularia, was isolated from a soil sample collected in the Chungnam province, Korea. Phylogenetic analyses based on the concatenated nucleotide sequences of internal transcribed spacer regions and partial sequences of large subunit rRNA, beta-tubulin, and RNA polymerase II subunit genes revealed that the strain was grouped in a clade with Triangularia species. However, it occupied a distinct phylogenetic position. We also observed morphological differences between strain KNUF-21-020 and closely related species. Here, we provided detailed descriptions, illustrations, and discussions regarding the morphological and phylogenetic analyses of the closely related species to support the novelty of this isolated species. The phylogenetic analyses and morphological observations indicate that the strain KNUF-21-020 represents a novel species in the genus Triangularia (family: Podosporaceae). We have designated this species as Triangularia manubriata sp. nov.
