Type species – Angustospora nilensis Abdel-Aziz, Fungal Divers. 78: 54 (2016).
Notes – Angustospora is an aquatic genus, which was introduced based on morphology and phylogenetic analyses. Angustospora resembles Caryospora in having large ascospores with a median septum and additional septa near the poles of the ascospores. Angustospora differs from species of Caryospora in having smaller ascomata and 8-spored, clavate asci. Phylogenetic results placed this genus in Testudinaceae but distant from Caryospora (Li et al. 2016a). This genus was collected from River Nile, Egypt, as a saprobe growing on submerged decayed wood with only the sexual morph (for morphology see Li et al. 2016a, Wijayawardene et al. 2018).
