MycoBank. MB 519444
On PDA, colonies circular to irregular form, margin entire, aerial mycelia dense, mycelia white. Pigment absent in medium. On CMD, colonies circular, margin erose to entire, aerial mycelia scant, mycelia white to yellow (10YR 8/8). Pigment absent in medium.

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, KUC21846 (= NIBRFGC000510470) ; KOREA, Jeollanam-do, Damyang, Juknokwon, 35.3284N, 126.9855E, isolated from a dead culm of Phyllostachys bambusoides, 20 Dec 2021, Sun Lul Kwon, KUC21848 (= NIBRFGC000510471) .
Notes. The morphology of conidia and conidiophores of our strains (KUC21846 and KUC21848) closely resembles those found in the original description, born from the sporodochia (Luo and Zhuang, 2008). While the morphological characteristics alone do not provide sufficient evidence to definitively identify our strain as M. gigas, the combination of molecular data and ecological traits is able to identify it M. gigas .
