Chaetosphaerulina I. Hino, Bull. Miyazaki Coll. Agric. Forest. 10: 62 (1938).

Index Fungorum number: IF 971; Facesoffungi number: FoF 06816; 6 morphological species (Species Fungorum 2020), molecular data unavailable.

Type species: Chaetosphaerulina yasudae I. Hino, Canad. J. Plant Sci. 10: 62 (1938).

Notes: Pirozynski (1972) transferred C. yasudae and C. vermicularispora to Herpotrichia. Sivanesan (1984) transferred these two species to Tubeufia. Crane (1998) transferred Thaxteriellopsis bambusicola and T. lignicola to Chaetosphaerulina. Boonmee et al. (2011) accepted Crane’s evaluation for Thaxteriellopsis bambusicola but reinstated T. lignicola as the type species of Thaxteriellopsis. Boonmee et al. (2014b) excluded Chaetosphaerulina from Tubeufiaceae. Lu et al. (2018b) accepted Chaetosphaerulina as a member of Tubeufiaceae based on morphological evidence. The ascomata of Chaetosphaerulina are ovoid to ellipsoid and covered with hairy setae, asci are cylindrical and slightly truncate at apex, with curved hyaline fusiform ascospores which are constricted at the median (Boonmee et al. 2011).
