On PDA, colonies low, flat, circular form, margin erose to entire, aerial mycelia dense, mycelia white, pigment absent in medium. On MEA, colonies circular form, margin filamentous to entire, aerial mycelia scant, mycelia hyaline to white, pigment absent. On OA, colonies circular form, margin entire, aerial mycelia little, mycelia white, pigment absent in medium. Coelomycetous asexual morph, Conidiomata pycnidia, single to grouped. Conidiophores branched, hyaline, thin-walled, bearing terminal a group of 2-5 phialides. Phialides lageniform, hyaline, (9.0-) 9.5-15(-16) × 2.0-3.0(-4.5) μm. Conidia ellipsoidal to obovoid, slightly apiculate base, hyaline, smooth, 3.0- 4.0(-4.5) × 1.5-2.0 μm. Chlamydospores not observed.
Distribution. Japan and Republic of Korea.
Habitat. On dead twigs or culms of Phyllostachys nigra var. henonis , P. pubescens , and P. bambusoides .
Specimen examined. KOREA, Jeollanam-do, Damyang, Juknokwon , 35.3284N, 126.9855E, isolated from a dead culm of Phyllostachys bambusoides , 20 Dec 2021, Sun Lul Kwon, KUC21845 (= NIBRFGC000510476) GoogleMaps .
Notes. The size of the conidia of T. punctulatum KUC 21845 (3-4 μm long) is slightly longer than that of T. punctulatum KT 3905 (epitype) (2-3.5 μm long) ( Sugita and Tanaka, 2022). However, other morphological features are comparable. The holotype and epitype strains were isolated from bamboo (dead twigs of Phyllostachys nigra var. henonis ) in Japan ( Sugita and Tanaka, 2022). Moreover, another specimen examined in the study was also isolated from bamboo (dead culm of Phyllostachys pubescens ). This suggests that T. punctulatum species prefer to have a habitat on the dead Phyllostachys species. Previous research has demonstrated that the Thyridium genus possesses enzymes and pathways responsible for the degradation of diesel fuel ( Deng et al., 2023). Consequently, it is postulated that this genus could be harnessed for the remediation of oil pollutants.
