1885, A.B. Langlois, No. 138 (NY, holotype of Amphisphaeria hypoxylon Ellis & Everh.). Notes Morphology Immotthia was introduced to accommodate a species of Amphisphaeria (A. hypoxylon), which

has bitunicate asci, and is characterized by superficial, ostiolate, periphysate, papillate ascomata, cellular pseudoparaphyses, bitunicate, 8-spored, cylindrical asci, ellipsoid, smooth, brown to reddish brown, 1-septate ascospores (Barr 1987a; Wang et al. 2004). Phylogenetic study None. Concluding remarks It seems that those Amphisphaeria species with bitunicate asci should be assigned to Pleosporales. Morphologically, Immotthia is somewhat comparable with Herpotrichia. Isthmosporella Shearer & J.L. Crane, Mycologia 91: 141 (1999). (Pleosporales, genera incertae sedis) Generic description Quisinostat purchase Habitat freshwater, saprobic. Ascomata small- to medium-sized, scattered, immersed, erumpent to superficial, globose, papillate, ostiolate, periphysate, membranous. Peridium 2-layered, outer layer composed of brown, find more pseudoparenchymatic, fusoid-cylindric cells, inner layer composed of fusoid, subhyaline to pale brown, compressed cells. Hamathecium of rare, broad, septate, interascal pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, oblong to clavate, with a short pedicel, ocular chamber not observed. Ascospores 3–4 seriate, cylindrical to fusoid, isthmoid at centre, constricted at septa, isthmus 1-septate, surrounded by a gelatinous

sheath. Anamorphs reported for genus: none. Literature: Shearer and Crane 1999. Type species Isthmosporella pulchra Shearer & J.L. Crane, Mycologia 91: 142 (1999).

Note the 2-celled isthmus in J and mucilaginous sheath in G and H. Scale bars: a = 50 μm, b–j = 20 μm Ascomata 240–330 μm diam., scattered on decorticated wood, immersed, erumpent to superficial, globose, black, papillate, papilla short, cylindrical, 60 μm long × 55 μm

wide, ostiolate, periphysate, membranous Nintedanib (BIBF 1120) (Fig. 38a). Peridium 2-layered, outer 3–4 cell layers composed of brown, pseudoparenchymatic, fusoid-cylindric cells, 2–6.5 μm long; inner layer composed of 5–7 rows of fusoid, subhyaline to pale brown compressed cells, 11–20 × 2–3.5 μm diam. (Fig. 38a and b). Hamathecium of rare, broad, septate, interascal pseudoparaphyses (Fig. 38f). Asci (95-)135–160(−175) × (25-)30–45(−60) μm, 8-spored, bitunicate, fissitunicate, oblong to clavate, with a short pedicel, ocular chamber not observed (Fig. 38c, d and e). Ascospores 80–105(−110) × (7-)8–10 μm, 3–4-seriate, cylindrical to fusoid, isthmoid at centre, sometimes bent at isthmus and becoming u- or v- shaped, end cells tapering, 12–17-phragmoseptate, constricted at septa, isthmus 1-septate, 2–5.5 × 2–4.5 μm diam.
