Index Fungorum number: IF 13; Facesoffungi number: FoF 06812; 3 morphological species (Species Fungorum 2020), molecular data unavailable.
Type species: Acanthophiobolus helicosporus (Berk. & Broome) J. Walker, Trans. Br. mycol. Soc. 58(3): 445 (1972).
≡ Sphaeria helicospora Berk. & Broome, Ann. Mag. nat. Hist., Ser. 2 9: 383 (1852).
Notes: Acanthophiobolus was introduced with A. helicosporus as the type species (Berlese 1893, as A. helminthosporus). Boonmee et al. (2011) reexamined the holotype of A. helicosporus and accepted Acanthophiobolus as a member of Tubeufiaceae. The ascomata of Acanthophiobolus are globose to subglobose, reddish brown to dark brown, with much longer red brown to dark brown setae, and asci are elongate-cylindrical with long filiform ascospores (Boonmee et al. 2011, 2014). Lu et al. (2018b) listed three species, A anogeissi, A. helicosporus, and A. indicus.
