Type species:
Belizeana tuberculata Kohlm. & Volkm.-Kohlm., 1987a. Bot. Mar., 30: 196.
Sexual morph: saprobic, Ascomata: 210-260 µm high, 220-230 µm in diam., subglobose to broadly ampulliform, at first immersed, later erumpent, ostiolate, epapillate or shortly papillate, black and carbonaceous above, light brown and leathery on the sides and base, single or gregarious. Ostioles: up to 20 µm in diam., filled with a tissue of hyaline cells, forming a textura angularis. Peridium: 20-31 µm thick on the sides and base, 37-50 µm around the ostiole, enclosing some deteriorating wood particles, with melanin incrustations in the upper half, hyaline in the lower half, composed of about 9-12 layers of polygonal cells with small lumina. Pseudoparaphyses: 2 µm in diam., simple, rarely branched or anastomosing, embedded in a gelatinous matrix, growing down from the roof of the locule, merging with thinner interascicullar filaments. Asci: 140-155 x 25-29 µm, 8-spored, cylindrical, short pedunculate, thick-walled, fissitunicate, without apical apparatus, with a small ocular chamber, parallel, maturing successively on an ascogenous tissue at the bottom of the locule. Ascospores: 17-24 x 10-15 µm, monostichously in the ascus, broad ellipsoidal, 1-septate, constricted at the septum, hyaline, wall thick, two layered, mature spores with tuberculate ornamentations between the two layers; tubercles 0.7-1.5 µm in diam.; young spores smooth, becoming delicately verruculose during maturation; outer layer eventually gelatinizing and forming a sheath. Asexual morph: Undetermined (Description based on Kohlmeyer and Volkmann-Kohlmeyer (1987) and Borse et al. (2012)).
