Material examined: ARGENTINA, Buenos Aires, Ramallo, on Eucalyptus viminalis Labill., May 1982, Romero 27/4-13 (BAFC 32036, holotype); Nov. 1982, on decorticated wood, Romero 35/4-13 (BAFC
32037, paratype). Notes Morphology Moristroma was formally established by Romero and Samuels (1991) based on its “cushion-shaped ascomata containing lots of locules with numerous asci inside, asci obclavate, polysporous, with a knob-shaped pedicel”. The bitunicate asci and numerous cellular pseudoparaphyses undoubtedly point it to Pleosporales, while the familial placement of Moristroma is uncertain, and it was temporarily assigned to Dacampiaceae by Romero and Samuels (1991), but AZD8931 concentration no 3-layered peridium is found. Eriksson (2006) assigned it to Teichosporaceae. Phylogenetic study None. Concluding
remarks The familial status of Moristroma cannot be determined yet. Morosphaeria Suetrong, Sakay., E.B.G. Jones & C.L. Schoch, Stud. Mycol. 64: 161 (2009). (Morosphaeriaceae) Generic description Habitat marine, saprobic. Ascomata large, solitary or gregarious, immersed to erumpent, subglobose or depressed with a flatted base, ostiolate, papillate, brown to black, coriaceous. Peridium thick. Hamathecium of dense, long cellular pseudoparaphyses, septate. Asci 8-spored, bitunicate, cylindrical, with short pedicels. Ascospores uniseriate to partially overlapping, ellipsoidal, hyaline, 1-3-septate, constricted at the septa, find more central cells larger, apical cells if present small and elongated, surrounded with mucilaginous sheath. Anamorphs reported for genus: none. Literature: Hyde Danusertib price and Borse 1986; Hyde 1991a, b; Suetrong et al. 2009; Zhang et al. 2009a. Type species Morosphaeria velataspora (K.D.

Ascomata 0.7–1.2 mm diam., solitary or gregarious, immersed to erumpent, subglobose or depressed, with a flattened base not easily removed from the substrate, ostiolate, epapillate or papillate, brown to black, coriaceous (Fig. 63a). Peridium thick, the upper part of the peridium composed of brown thick-walled cells of textura angularis, cells are smaller and wall thicker near the apex, at the rim is composed of vertical, parallel, brown, elongate cells, wedge-shape in section (Fig. 63a). Hamathecium of dense, long cellular pseudoparaphyses, 1.1–1.7 μm broad, septate.
