lineolatispora

Type species:

Trematosphaeria pertusa (Pers.) Fuckel, Jahrbücher des Nassauischen Vereins für Naturkunde 23-24: 161 (1870)

Marine species:

Trematosphaeria lineolatispora K.D. Hyde, 1992c. Mycol. Res., 96: 28.

Sexual morph: saprobic, Ascomata: 90-180 μm high, 210-360 μm diam., conoid to subglobose, immersed with a flattened base, ostiolate, papillate, as darkened spots on wood surface, clypeate, solitary or gregarious. Necks: up to 150 μm long, 75-100 μm diam., periphysate, brown. Peridium: up to 25 μm thick, at the sides composed of one layer of pseudoparenchymatous cells of textura angularis, becoming elongate towards the ostiole and fusing with the clypeus. The peridium is thin at the base. Pseudoparaphyses: 2-4 μm wide, straight, cellular, septate, appearing trabeculate, in a gel, forming a thick packing tissue between the asci and extending into the neck. Asci: 120-204 x 14-18 μm, 8-spored, cylindrical-sub clavate, bitunicate, thick-walled, pedunculate, with an ocular chamber and faint ring structure, arising from the base and lower sides of the ascoma. Ascospores: 34-48 x 7-10 μm, 1-2-seriate, fusiform, mostly 5-septate, third cell from the top the largest, cinnamon-brown in centre with lighter end cells, hyaline when young, surface covered in striations and surrounded by a mucilaginous sheath. Asexual morph: Undermined (Description based on Hyde (1992)).
