Concluding remarks Orange and greenish plain apices HDAC inhibitor exist in the specimen we examined, which is different from records as “orange, bright or dull reddish plain apices” by Barr (1984). This might be

because different specimens have different colours, or there may be a variation of apical colour within a single species, as both orange and green can coexist on the same ascoma (see Fig. 17a). The coloured apical rim, together with the trabeculate pseudoparaphyses as well as the presence of subiculum make Byssosphaeria readily distinguishable from other morphologically comparable genera, e.g. Herpotrichia and Keissleriella (Hyde et al. 2000). Calyptronectria Speg., Anal. Mus. nac. Hist. nat. B. Aires 19: 412 (1909). (Melanommataceae) Generic description Habitat terrestrial, saprobic. Ascomata small- to medium-sized, solitary, scattered, or in small groups, immersed, lenticular to subglobose, papillate, ostiolate. Hamathecium of long, filliform pseudoparaphyses, branching and anastomosing, embedded in Selleck Foretinib mucilage. Asci 4- to 8-spored, bitunicate, fissitunicate, cylindrical to cylindro-clavate, with a short, furcate pedicel. Ascospores muriform, broadly fusoid to fusoid with broadly

to narrowly rounded ends, hyaline. Anamorphs reported for genus: none. Literature: Barr 1983; Rossman et al. 1999; Spegazzini 1909. Type species Calyptronectria platensis Speg., Anal. Mus. nac. Hist. nat. B. Aires 19: 412 (1909). (Fig. 18) Fig. 18 Calyptronectria

CYC202 chemical structure platensis (from LPS 1209, holotype). a Appearance of ascomata scattered in the substrate (after removing the out layer of the substrate). Note the protruding papilla. b Section of an ascoma. c Section of the partial peridium. Note the lightly pigmented Branched chain aminotransferase pseudoparenchymatous cells. d Released ascospores with mucilaginous sheath. e Eight-spored asci in hamathecium and embedded in gel matrix. f Ascus with a short pedicel. Scale bars: a = 0.5 mm, b = 100 μm, c = 50 μm, d–f = 10 μm Ascomata 120–270 μm high × 170–400 μm diam., solitary, scattered, immersed, lenticular to subglobose, papillate, ostiolate (Fig. 18a and b). Apex with a small and slightly protruding papilla. Peridium 18–30 μm wide, comprising two types of cells, outer layer composed of pseudoparenchymatous cells, cells 3–6 μm diam., cell wall 1–2 μm thick, inner layer comprising less pigmented cells, merging with pseudoparaphyses (Fig. 18b and c). Hamathecium of long, filliform pseudoparaphyses, 1–2 μm broad, branching and anastomosing, embedded in mucilage. Asci 98–140 × 12.5–20 μm (\( \barx = 107 \times 15.4\mu m \), n = 10), 8-spored, sometimes 4-spored, bitunicate, fissitunicate, cylindrical to cylindro-clavate, with a short, furcate pedicel, 12–20 μm long, with an ocular chamber (to 4 μm wide × 3 μm high) (Fig. 18e and f). Ascospores 17–22.5 μm × (6.3-)7.5–10 μm (\( \barx = 19.8 \times 7.
