Celosporium laricicola Tsuneda & M.L. Davey [as ‘larixicolum‘], Botany 88(5): 473 (2010)

Index Fungorum number: IF 548321; Facesoffungi number: FoF 00112

The diameter of the colonies cultured on the PDA medium was 15-17 mm, and the colonies showed black regular margins. The front side of the colonies was olive-yellow or dark olive-green and the reverse side was black in color. The colonies had a moist surface and exhibited furrows at the center. The color of the medium around the colonies changed to orange. The diameter of the colonies cultured on MEA medium was 8-11 mm, and the colonies showed brown regular margins. Blasticconidia and endoconidia were lined together. Blastic conidia were ovoid, with a size of (2.21-) 2.78 (-3.23)×(1.69-) 1.98 (-2.36) μm. Endoconidia consisted of 1-3 globular cells, and their size was (6.90-) 10.36(-12.35) × (5.89-) 7.83 (-10.36) μm.

Specimen examined – Baengnyeongdo Island, Ongjin-gun, Incheon, Republic of Korea; 37°57’N, 124°38’E, May 15, 2019, isolated from the leaves of Pinus thunbergii, NIBR No. NIBRFGC000508554.

GenBank accession numbers – ITS: ON430568, LSU : ON430567

Note – Celosporium laricicola was isolated from the twigs of Larix lyallii by Tsuneda & Davey in 2010. Celosporium comprises only one species, Celosporium laricicola. It is characterized by the formation of endoconidia composed of 1–3 cells within a cellular clump. The ITS region of KNUE19E084 showed 99.01% similarity with that of FJ997287, and the LSU region showed 99.66% similarity with that of FJ997288. Through morphological and molecular analysis, KNUE19E084 discovered in this study, was identified as Celosporium laricicola, an unrecorded species in Korea.
