MycoBank. MB 842152

On PDA, colonies circular form, margin erose to entire, aerial mycelia dense, mycelia white, pigment absent in medium. On OA, colonies circular form, margin entire, aerial mycelia dense, mycelia white, pigment absent in medium. On SNA, colonies circular form, margin erose to entire, aerial mycelia scant, mycelia white, pigment absent in medium. Conidiophores borne on aerial mycelia, branched, hyaline, thin-walled, bearing terminal a group of 2-5 phialides. Phialides subulate to subcylindrical, hyaline, (11-)13-21(-26) × 2.5-3.0(-4.0) μm. Microconidia oval, hyaline, thin-walled, aseptate, (6.0-)8.0- 11.0(-13.5) × (1.8-)2.0-3.0(-3.5) μm. Macroconidia not observed. Chlamydospores terminal, globose, rough, thick-walled, 6.0-8.0 μm diam.

Distribution. China; and Republic of Korea.

Habitat. bamboo, culm of unidentified bamboo and Phyllostachys pubescens .

Specimen examined. KOREA, Jeollabuk-do, Gochang, Gochangeupseong, 35.4303N, 126.7031E, isolated from a culm of Phyllostachys pubescens, 18 Mar 2021, Sun Lul Kwon, KUC21851 (= NIBRFGC000510466) ; KOREA, Jeollanam-do, Gwangju, Mudeungsan National Park, 35.1267N, 126.9685E, isolated from a culm of bamboo, 23 Sep 2020, Sun Lul Kwon, KUC21852 (= NIBRFGC 000510467) ; KOREA, Jeollanam-do, Gwangju, Mudeungsan National Park, 35.1267N, 126.9685E, isolated from a culm of bamboo, 23 Sep 2020, Sun Lul Kwon, KUC21853 (= NIBRFGC000510468) .

Notes. The size of the aerial phialides of F. bambusarum KUC 21851 (13-21 μm long) is shorter than that of F. bambusarum LC 7180 (ex-type) (23-30 μm long) (Wang et al., 2022a). However, other morphological features and habitats are comparable (both strains are found from bamboo species).
