Protoscypha Syd., Annls mycol. 23(3/6): 402 (1925).
Index Fungorum number: IF 4394; Facesoffungi number: FoF 07901, 2 morphological species (Species Fungorum 2022), no molecular data available.
Parasitic on living leaves of Miconia thomasiana. Sexual morph: Ascostromata superficial, solitary, scattered, occurring on the lower leaf surface, discoid or cup-shaped, slightly convex or raised pulvinate, semi-immersed, flattened and thickened at the base, occurring in lesions of light brown regions and surrounded by external black mycelial areas up to 2–3 mm diam., multi-locular, opening by rupturing or cracking of the apical ascostromata. Peridium thick, composed of dark cells arranged in a textura angularis. Hamathecium comprising hyaline, relatively wide, anastomosing, septate pseudoparaphyses, often with swollen cells, intermixed with reddish brown colouration, and surrounded by a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, subglobose, oblong, broadly cylindrical to subclavate, somewhat thickened at the apex, short pedicellate, with a wide, but short ocular chamber. Ascospores 2–3-seriate in the ascus, muriform, oblong to oval-sub ellipsoid, 3–7 trans-septate, with 1 longitudinal septa in each transverse row, highly constricted at the septum, hyaline, pale brown or light brown, surrounded by a thin gelatinous sheath. Asexual morph: Unknown (adapted from Hyde et al. 2013).
Type species: Protoscypha pulla Syd.
Notes: Protoscypha is characterised by solitary, scattered ascostromata, broadly cylindrical to subclavate asci and oblong to oval-subellipsoid, 3–7 trans-septate ascospores, with 1 longitudinal septum in each transverse row. Protoscypha is a distinct genus in Protoscyphaceae but molecular data is needed to confirm the placement of the genus as well as the family because the type species is yet to be sequenced. More taxa are needed to verify the status of Protoscypha.
