Strains of these genera need to be collected and analyzed and their relationship with Sporormia established. Trematosphaeria Fuckel, Jb. nassau. Ver. Naturk. 23–24: 161 (1870). (Trematosphaeriaceae) Generic description Habitat terrestrial

or freshwater, saprobic. Ascomata subglobose, unilocular, erumpent to superficial, with papillate ostiole. Peridium thin, comprising several cell types. Hamathecium of dense, delicate, filliform, septate pseudoparaphyses. Asci bitunicate, fissitunicate, cylindro-clavate, normally 8-spored. Ascospores ellipsoid-fusoid to biconic, septate, smooth to finely verruculose, brown. Anamorphs reported for genus: hyphopodia-like (Zhang Wortmannin order et al. 2008a).

Ascomata selleck chemical 350–550 μm Celecoxib high × 320–480 μm diam., solitary, scattered, or in groups, initially immersed, becoming erumpent, to semi-immersed, subglobose, black; apex with a short ostiole usually slightly conical and widely porate, to 100 μm high (Fig. 92a and b). Peridium 48–55 μm wide laterally, to 80 μm at the apex, thinner at the base, 30–40 μm thick, coriaceous, 3-layered, comprising several cell types, one is of small heavily pigmented thick-walled cells of textura angularis, cells 4–8 μm diam., cell wall 1.5–3 μm thick in places with columns of textura prismatica orientated perpendicular to the ascomatal surface, apex cells smaller and walls thicker, forming thick-walled cells of textura pseudoparenchymata, and larger, paler cells of mixture of textura epidermoidea and textura angularis at the base (Fig. 92b, c and h). Hamathecium of dense, filamentous, 1.5–2.5 μm broad, septate pseudoparaphyses, embedded in mucilage, branching and anastomosing between and above the asci (Fig. 92d, e and f). Asci 100–145 × 15–17 μm (\( \barx = 118 \times 15.5 \mu \textm \), n = 10), 8-spored, bitunicate, fissitunicate, cylindro-clavate, with a short, thick, furcate pedicel which is 12–30 μm long, with a truncate ocular chamber (Fig. 92d, e, f, g and i). Ascospores 27.5–32.5 × 7.5–8.5 μm (\( \barx = 29.
