Fungal Diversity Fig. 5 Appendispora frondicola (from BRIP 21354, holotype). a Immersed ascomata on host surface. b Valsoid configuration of the ascomata. c Cylindrical ascus. d Squash showing asci and numerous pseudoparaphyses. e Thin strands of anastomosing pseudoparaphyses. f, g Ascospores with one or two appendages. Scale bars: a, b=0.5 mm, c–g=30 μm 13 μm, 8-spored, bitunicate, fissitunicate, cylindrical, with an ocular chamber and faint ring, with short pedicels (Fig. 5c and d). Ascospores 21–30×7–9 μm, uniseriate to partially overlapping, fusoid, brown, 1-septate, slightly constricted at the septum, with an irregular ridged ornamentation and 3–5 narrow appendages at each end (Fig. 5f and g). Anamorph: none reported. Material examined: BRUNEL, Jalan, Muara, Simpang 835, on dead rachis of Oncosperma horridum on forest floor, Nov. 1992, K.D. Hyde 1652 (BRIP 21354, holotype). Notes Morphology Appendispora was described as a saprobe of palm, and is characterized by small, immersed ascomata, bitunicate, fissitunicate asci, trabeculate pseudoparaphyses, brown, 1- septate, appendaged ascospores with irregular wall striations (Hyde 1994a).Basedonitstrabeculatepseudoparaphyses embedded within gel matrix and its brown ascospores, Appendispora was assigned to Didymosphaeriaceae (Barr 1987b; Hyde1994a). Phylogenetic study None. Concluding remarks The saprobic habitat and association with monocots, cylindrical asci, trabeculate pseudoparaphyses as well as its brown, 1-septate ascospores make it difficult to determine a better phylogenetic position than Didymellaceae.
Fungal Diversity Ascorhombispora L. Cai & K.D. Hyde, Cryptog. Mycol. 28: 294 (2007). (Pleosporales, genera incertae sedis) Generic description Habitat freshwater, saprobic. Ascomata solitary or gregarious, superficial, globose to subglobose, dark brown to black, short papillate, ostiolate, coriaceous. Peridium relatively thin, textura angularis in longitudinal section, 2-layered. Hamathecium not observed. Asci 8-spored, obpyriform, broadly clavate to saccate, pedicellate, bitunicate, apex rounded, persistent. Ascospores overlapping 2-3-seriate, broadly fusoid to rhomboid, thick-walled, surrounded by mucilaginous sheath, 3- euseptate, not constricted at septa, median septum wide, forming a darker band, central cells large, trapezoid, dark brown to black, verruculose, polar end cells small and paler. Anamorphs reported for genus: none. Literature: Cai and Hyde 2007. Type species Ascorhombispora aquatica L. Cai & K.D. Hyde, Cryptog. Mycol. 28: 295 (2007). (Fig. 6) Ascomata 140–170 μm high×150–185 μm diam., solitary or gregarious, superficial, globose to subglobose, dark brown to black, short papillate, ostiolate, ostioles rounded, small, coriaceous. Peridium relatively thin, 10–18 μm wide, textura angularis in longitudinal section, composed of two layers of angular cells, outer later dark brown to black, relatively thickwalled, inner layer hyaline, relatively thin-walled (Fig. 6a and b). Hamathecium not observed. Asci 100–198×72–102 μm (x ¼ 186 88mm, n=15), 8-spored, obpyriform, broadly clavate to saccate, pedicellate, bitunicate, apex rounded, deliquescent (Fig. 6c, d and e). Ascospores 30.5–45×16– 26.5 μm (x ¼ 38:5 21mm, n=25), overlapping 2-3-seriate, broadly fusoid to rhomboid, thick-walled, surrounded by mucilaginous sheath, 3-euseptate, not constricted at septa, median septum wide, forming a darker band, central cells large, trapezoid, 11–18 μm long, dark brown to black, verruculose, polar end cells small, hemispherical, 3.5–4 μm long, subhyaline to pale brown, smooth (Fig. 6f). Anamorph: none reported. Material examined: CHINA, Yunnan, Jinghong, on submerged bamboo in a small forest stream, 26 Jan. 2003, leg. det. L. Cai, CAI-1H31 (HKU(M) 10859, holotype). Notes Morphology Ascorhombispora was introduced as a monotypic genus from freshwater by Cai and Hyde (2007), and is characterized by superficial, coriaceous, non-stromatic ascomata, large, saccate asci; lack of interascal filaments and trapezoid (rhombic), 3-septate, dark brown to black ascospores with smaller end cells which are subhyaline to pale brown. Ascorhombispora is most comparable with Caryospora and Zopfia. But the globose to subglobose ascomata and thin peridium, saccate asci lacking interascal pseudoparaphyses, and the 3-septate, rhomboid ascospores with the paler end cells of Ascorhombispora differs from those of Caryospora (Cai and Hyde 2007). Phylogenetic study Phylogenetic analysis based on either SSU or LSU rDNA sequences indicated that Ascorhombispora aquatica belongs to Pleosporales, but its familial placement was left undetermined (Cai and Hyde 2007). Concluding remarks The sac-shaped asci and absence of pseudoparaphyses are uncommon in Pleosporales, especially among those from freshwater. Asteromassaria Höhn., Sber. Akad. Wiss. Wien, Math.- naturw. Kl., Abt. I 126: 368 (1917). (?Morosphaeriaceae) Generic description Habitat terrestrial, saprobic. Ascomata medium-sized, clustered, at first immersed and then breaking through the host surface and becoming superficial, globose, subglobose, coriaceous. Peridium 2-layered, thicker near the base. Hamathecium of dense, septate, cellular pseudoparaphyses which branch and anastomosing frequently between and above asci. Asci (4-)8-spored, bitunicate, cylindro-clavate to clavate, with a short truncated pedicel and a small ocular chamber. Ascospores obliquely uniseriate and partially overlapping to biseriate, fusoid to fusoid-ellipsoidal, pale brown when mature, 1-septate, some becoming 3-septate when old, constricted at the median septum. Anamorphs reported for genus: Scolicosporium (Sivanesan 1984). Literature: Barr 1982a; b; 1993a; Boise 1985; Shoemaker and LeClair 1975; Sivanesan 1987; Tanaka et al. 2005. Type species Asteromassaria macrospora (Desm.) Höhn., F. von, Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. I 126: 368 (1917). (Fig. 7) ≡ Sphaeria macrospora Desm., Ann. Sci. Nat. Bot. 10: 351 (1849). Ascomata 400–600 μm high×450–650 μm diam., 4–20 clustered together, at first immersed and then breaking through the host surface and becoming superficial, globose,
