Type species: Acanthohelicospora pinicola Boonmee & K.D. Hyde, Fungal Diversity 68(1): 251 (2014).

Notes: Acanthohelicospora was introduced based on morphological and phylogenetic evidence. Its sexual morph is characterized by superficial ascomata covered by setae which taper to an acute apex, 8-spored, bitunicate asci and slightly curved, fusiform ascospores, which taper towards rounded ends (Boonmee et al. 2014b; Lu et al. 2018b). Its asexual morph is characterized by helicosporous hyphomycetous, which are similar to Helicosporium in conidiophores, conidiogenous cells and conidial morphology (Lu et al. 2017a, 2018b). Four species are accommodated in this genus, A. aurea, A. guianensis, A. pinicola, and A. scopula (Lu et al. 2018b).
