Notes – Pteridiospora is characterized by superficial, mammiform to conical, carbonaceous ascomata with ostiole, trabeculate pseudoparaphyses, 8-spored, broad-cylindrical to cylindric-clavate asci with short pedicel, and hyaline to brown, obclavate to ellipsoidal, septate, asymmetrical ascospores surrounded by irregular, mucilaginous sheath (Phookamsak et al. 2015b, Hyde et al. 2018). Pteridiospora is similar to Astrosphaeriella, but differs in its asymmetrical ascospores, with distinctive mucilaginous sheath. Phylogenetic analyses show that Pteridiospora is a sister clade to Astrosphaeriella within Astrosphaeriellaceae (Phookamsak et al. 2014b, 2015b, Hyde et al. 2018).
Type species: Pteridiospora javanica Penz. & Sacc., Malpighia 11: 399 (1897).
Other accepted species: Species Fungorum – search Pteridiospora.
