Acanthophiobolus Berl., Atti Congl. Bot. Intern. Di Genova, 1892: 571 (1893) [1892]

 Saprobic on cloth. Sexual state:Ascomata superficial, globose to subglobose, reddish-brown to dark brown, ostiole central, with red brown to dark brown setae, setae septate, tapering towards apex. Peridium comprising several-layers; inner layer composed of textura prismatica-porrecta and hyaline to pale, outer layer composed of 2–3 layers of dark brown cells of textura angularis. Hamathecium comprising filiform pseudoparaphyses. Asci 8-spored, bitunicate, elongate, cylindro-clavate, short pedicellate. Ascospores spirally arranged in ascus, filiform, septate, hyaline(from Boonmee et al. 2011).Asexual state: Unknown.

Notes: This monotypic genus for which no molecular data are available was illustrated in Boonmee et al. (2011). The genus differs from Acanthostigma morphologically. The ascomata of Acanthophiobolusare bright coloured with much longer setae, and the asci are elongate-cylindrical with long filiform, trans-septate ascospores. We therefore maintain Acanthophiobolusas a distinct genus in Tubeufiaceae.

Type species:Acanthophiobolus helminthosporus (Rehm) Berl., Die Pilze des Weinstockes, Vienna: 571 (1893) [1892]
