Ascospores 35–43 × 14–17 μm, irregularly biseriate in the ascus, hyaline, aseptate, ellipsoid to rhomboid, smooth, thin-walled, widest in the middle, with a mucilaginous sheath. Conidiomata Stem Cell Compound Library ic50 often found in the same ascostroma. Paraphyses hyphae-like, branched, arising between the conidiogenous cells. Conidiogenous cells hyaline,
cylindrical, sometimes branched at the base, discrete. Conidia 42–47(−55) × 8.5–12.5 μm, hyaline, aseptate, fusiform, widest in the middle, apex acute, base truncate with a minute marginal frill, surrounded by a mucilaginous sheath. Material examined: GERMANY, Bavaria, Munich, English Garden, on dead twigs of Quercus robur, 8 July 2004, A.J.L. Phillips (LISE 95179, epitype). Neodeightonia C. Booth, in Punithalingam, Mycol. Pap. 119: 17 (1970)  Saprobic on dead wood and leaves of monocotyledons. Ascostromata brown to dark brown, uniloculate, immersed to erumpent, globose to subglobose. Ostiole circular, central. Peridium of dark brown-walled cells of textura angularis. Pseudoparaphyses hyphae-like, septate, constricted at the septa. Asci 8−spored, bitunicate, fissitunicate, clavate to cylindrical-clavate,
apically rounded with an ocular chamber. Ascospores uniseriate or irregularly biseriate, hyaline, aseptate, ellipsoidal-fusiform or fusiform, surrounded or not surrounded by a complex sheath. Pycnidia uniloculate or multilocular, semi-immersed, solitary, globose, covered by mycelium, wall IKBKE composed of dark brown thick-walled textura angularis, becoming thin-walled and hyaline toward the inner region. Paraphyses hyaline, cylindrical. Conidiogenous cells learn more holoblastic, hyaline, aseptate, cylindrical to subcylindrical. Conidia initially hyaline, aseptate, ellipsoid to obovoid, thick-walled with granular content, rounded at apex, occasionally truncate at base. Aged conidia becoming cinnamon to sepia, and 1−septate, brown to dark brown. Notes: Neodeightonia was introduced by
Booth (Punithalingam 1969). However, von Arx and Müller (1975) transferred the type of the genus, N. subglobosa, to Botryosphaeria, reducing Neodeightonia to synonymy. Phillips et al. (2008) reinstated this genus which is distinguishable from Botryosphaeria morphologically (based on the dark, 1−septate ascospores) and phylogenetically (Phillips et al. 2008, Abdollahzadeh et al. 2009) and described a new species N. phoenicum. Liu et al. (2010) added the fourth species, N. palmicola based on studies on morphology of the sexual and asexual morphs and phylogenetic data. Generic type: Neodeightonia subglobosa C.
