Fungal Diversity dense, long trabeculate pseudoparaphyses, anastomosing and branching between the asci. Asci bitunicate, fissitunicate, cylindrical to cylindro-clavate, with a short furcate pedicel, with a big and truncate ocular chamber. Ascospores obliquely uniseriate and partially overlapping, narrowly fusoid to fusoid or broadly fusoid with tapering or narrowly rounded ends, hyaline to pale brown or brown, muriform. Anamorphs reported for genus: coelomycetous with muriform conidia (see Liu 2009). Literature: Cheng et al. 2004; Hino 1961; Kishi et al. 1991; Liu 2009; Morakotkarn et al. 2008. Type species Shiraia bambusicola Henn., Bot. Jb. 28: 274 (1900). (Fig. 88) Ascostroma 1–1.5 cm high×1–2.5 cm diam., subglobose, oblong to irregular, slightly pink with cracking surface. Ascomata 350–800 μm high×300–700 μm diam., subglobose, gregarious on the surface layer of ascostroma, immersed, ostiolate, with a small black opening seen on the surface of the ascostroma, ostiole rounded, the inner tissue of ascostroma carnation red (Fig. 88a and b). Hamathecium of dense, long trabeculate pseudoparaphyses, 0.8–1.5 μm broad, anastomosing and branching between the asci. Asci 300– 425×20– 35 μm (x ¼ 360:5 28mm, n=10), 6-spored, bitunicate, fissitunicate, cylindrical to cylindro-clavate, with a short furcate pedicel, up to 50 μm long, with a big and truncate ocular chamber (Fig. 88c and d). Ascospores 62.5–80×17.5– 22.5 μm (x ¼ 72:3 19:3mm, n=10), obliquely uniseriate and partially overlapping, narrowly fusoid to fusoid with tapering or narrowly rounded ends, hyaline turning pale brown when mature, muriform, with 9–13 transversal septa, 1–3 longitudinal septa in central cells, slightly constricted at the septa, usually with a gelatinous cap at each end (Fig. 88e, f and g). Anamorph: coelomycetous with muriform conidia (see Liu 2009). Material examined: CHINA, Zhejiang, Hangzhou, Panan, on bamboom, 15 Jun. 2009, leg. Liu Yongxiang (IFRD 2040). Notes Morphology Shiraia is reported as a parasite on branches of several genera of bamboo distributed mainly in southern regions of China and Japan (Hino 1961; Kishi et al. 1991; Liu 2009). Shiraia is characterized by its bambusicolous habitat, large ascostroma and muriform ascospores. Asci comprise 6 ascospores in this study and some previous studies (Hino 1961; Liu 2009). Shiraia bambusicola is well studied because of its medical effect in anticancer treatment (Kishi et al. 1991). Phylogenetic study Based on the SSU and ITS rDNA sequences analysis, its pleosporalean status was verified, and Shiraia was suggested to be closely related to Leptosphaeriaceae and/or Phaeosphaeriaceae (Pleosporineae) (Cheng et al. 2004). Based on the molecular phylogenetic analysis, another Shiraia-like fungus was reported which produced distinctive prawn-shaped conidioma-like structures (Morakotkarn et al. 2008), and differed from conidiomata in the anamorph of S. bambusicola described by Liu (2009). Concluding remarks A relatively broad species concept of Shiraia bambusicola is currently used, which could comprise several species. Sinodidymella J.Z. Yue & O.E. Erikss., Mycotaxon 24: 295 (1985). (Teichosporaceae) Generic description Habitat terrestrial, saprobic? Ascomata medium to large, scattered, or in small groups, immersed, erumpent, to superficial, globose, subglobose, coriaceous, apex flattened, with radial ridges arranged around the central region. Peridium thick, 2-layered. Hamathecium of dense, broadly trabeculate pseudoparaphyses, anastomosing and branching between the asci. Asci 8-spored, with a short, furcate pedicel, bitunicate, cylindrical. Ascospores broadly ellipsoid, hyaline, becoming pale brown when mature, 1-septate, constricted at the median septum. Anamorphs reported for genus: none. Literature: Yue and Eriksson 1985. Type species Sinodidymella verrucosa (Petr.) J.Z. Yue & O.E. Erikss., Mycotaxon 24: 295 (1985). (Fig. 89) ≡ Amphididymella verrucosa Petr., Meddn Göteb. Bot. 17: 129 (1947). Ascomata 620–930 μm high×800–1250 μm diam., scattered, or in small groups, immersed, becoming erumpent, to nearly superficial, globose, subglobose, coriaceous, apex flattened, with 3–6 radial ridges arranged around the central region, with a flattened base not easily removed from the substrate, wall black, roughened (Fig. 89a and b). Peridium 100–150 μm thick, thinner at the base, 2-layered, outer layer thin, up to 40 μm thick, composed of small heavily pigmented thick-walled cells of textura globulosa, cells up to 5 μm diam., cell wall 3–6 μm thick, inner layer thick, composed of
