Notes: Boonmee et al. (2014b) reported that A. minuta (ANM810, ANM818 and ANM238) is related to two strains of A. multiseptatum (ANM475 and ANM665) which represented Acanthostigmina. The ascomata of Acanthostigmina are globose to subglobose, dark brown, and covered by sparse dark brown to black setae, and asci are broadly cylindric-subclavate with curved fusiform ascospores (Boonmee et al. 2014b). Lu et al. (2018b) accepted two species, A. minuta and A. multiseptatum.
