Angustimassarina was introduced by Thambugala et al. (2015) to accommodate A. populi as the generic type. Angustimassarina members have uniloculate ascomata with a pore-like opening or that open through the cracks of the host surface and fusiform to cylindrical or ellipsoidal-fusiform, septate, hyaline ascospores, becoming ocher brown at maturity (Thambugala et al. 2015, Hyde et al. 2019). The asexual morph of this genus comprises micronematous to semi-macronematous, pale brown conidiophores, integrated, terminal, holoblastic, short-cylindrical to elongate-cylindrical, conidiogenous cells and solitary, elongate-clavate, pale to dark brown, 1–3-septate, conidia (Thambugala et al. 2015). Twelve Angustimassarina epithets are listed in Index Fungorum (2022).
Type species: Angustimassarina populi Thambug. & K.D. Hyde, in Thambugala et al., Fungal Diversity 74: 254 (2015).
Other accepted species: Species Fungorum – search Angustimassarina.
