Note the thin peridium with cells of textura angularis. d–g Asci with short pedicels. h Ascospores. Note the 2-septate hyaline ascospore. Scale bars: a, b=100 μm, c=50 μm, d–h=10 μm Falciformispora K.D. Hyde, Mycol. Res. 96: 26 (1992). (Trematosphaeriaceae) Generic description Habitat freshwater, saprobic. Ascomata small, scattered to gregarious, erumpent to nearly superficial, depressed globose to ovoid, black, ostiolate, epapillate, coriaceous. Peridium thin, comprising two cells types, outer layer composed of thick-walled cells of textura angularis, inner layer composed of hyaline compressed cells. Hamathecium long and cellular pseudoparaphyses, septate, embedded in mucilage. Asci 8-spored, bitunicate, fissitunicate, broadly clavate to fusoid, with a short, thick pedicel. Ascospores
Fungal Diversity fusoid to somewhat clavate, hyaline, usually slightly curved, multi-septate. Anamorphs reported for genus: none. Literature: Hyde 1992b; Raja and Shearer 2008. Type species Falciformispora lignatilis K.D. Hyde, Mycol. Res. 96: 27 (1992). (Fig. 32) Ascomata 180–270 μm high×250–340 μm diam., scattered to gregarious, erumpent and eventually superficial, depressed globose to ovoid, black, ostiolate, epapillate, coriaceous (Fig. 32a). Peridium up to 35 μm wide, comprising two cell types, outer layer composed of thick-walled cells of textura angularis, upto8μm diam., cell wall up to 5 μm thick, inner layer composed of hyaline compressed cells, cells 12×3 μm diam., cell wall 1–1.5 μm thick (Fig. 32a). Hamathecium long and cellular pseudoparaphyses, 2–3 μm broad, septate, embedded in mucilage. Asci 115–130×23–31 μm, 8-spored, bitunicate, fissitunicate, broadly clavate to fusoid, with a short, thick pedicel, 8–15 μm long,withanocularchamber(to5μm wide×3 μm high) (Fig. 32b and c). Ascospores 42–50×8– 10 μm, 2–3 seriate, fusoid to somewhat clavate, hyaline, usually slightly curved, 6–8-septate, mostly 7-septate, slightly constricted at all septa, smooth-walled, surrounded by a thin mucilaginous sheath which is longer at the base (up to 20– 30 μm) (Fig.32d, e and f). Anamorph: none reported. Material examined: MEXICO, Nova Hispania, mangrove near Boca de Pascuales, saprobic on immersed intertidal mangrove wood, Mar. 1988, K.D. Hyde (BRIP 16972, holotype). Notes Morphology Falciformispora was formally established by Hyde (1992b) as a monotypic genus and was assigned to Pleosporaceae by comparing with Setosphaeria, but Setosphaeria has the anamorphic stage of Exserohilum and is exclusively parasitic on Gramineae unlike Falciformispora. The setae on the ascomata of Setosphaeria could also serve as a distinguishing character from Falciformispora. Raja and Shearer (2008) also collected this species from freshwater in Florida. They considered that the species was more closely related to Chaetomastia than Setosphaeria, but that Falciformispora differed in having hyaline ascospores. Phylogenetic study Phylogenetic analyses in Schoch et al. (2009) and Suetrong et al. (2009) placed Falciformispora lignatilis in Trematosphaeriaceae in proximity to another marine species associated with mangroves, Halomassarina thalassiae. Concluding remarks Phylogenetic work confirmed that the saprobic habitat of Falciformispora is inconsistent with most other members of Pleosporaceae. The hyaline multi-septate ascospores with a mucilaginous sheath indicate affinities to Lophiostomataceae but this is not supported in DNA sequence comparisons. Carinispora is also similar and may be related. Hadrospora Boise, Mem. N. Y. bot. Gdn 49: 310 (1989). (?Phaeosphaeriaceae) Generic description Habitat terrestrial (or freshwater?), saprobic. Ascomata small- to medium-sized, solitary, scattered, or in groups, immersed to nearly superficial, globose to subglobose, papillate. Peridium thin, comprising pseudoparenchymatous cells. Hamathecium dense, narrowly cellular, embedded in mucilage. Asci bitunicate, fissitunicate, oblong to ovoid, with a short pedicel. Ascospores ellipsoid to broadly fusoid with narrow ends, reddish brown, multi-septate, constricted at the primary septum. Anamorphs reported for genus: Zalerion (Tanaka and Harada 2003a). Literature: Boise1984, 1989; Fisher and Webster 1992;Shearer and Crane 1971; Tanaka and Harada 2003a; Webster1993. Type species Hadrospora fallax (Mouton) Boise, Mem. N. Y. bot. Gdn 49: 310 (1989). (Fig. 33) ≡ Trematosphaeria fallax Mouton, Bull. Soc. R. Bot. Belg. 25: 155, (1886). Ascomata 130–240 μm high×200–330 μm diam., solitary, scattered or in groups, initially immersed, becoming erumpent to nearly superficial, with basal wall remaining immersed in host tissue, not easily removed from the substrate, globose or subglobose, roughened, papillate, coriaceous (Fig. 33a). Peridium 30–45 μm wide, comprising cells of pseudoparenchymatous,upto12.5×9μm diam. (Fig. 33b and c). Hamathecium of dense, narrowly cellular pseudoparaphyses, 1–2 μm broad, embedded in mucilage. Asci 150–200×40–60 μm (x ¼ 171:5 48mm, n=10), 8-spored, bitunicate, fissitunicate, oblong to ovoid, with a short pedicel, 10–24 μm long, with a ocular chamber (to 5 μm wide×6 μm high) (Fig. 33d). Ascospores 55–80×16–22 μm (x ¼ 67:1 18:1mm, n=10), biseriate to 4-seriate, ellipsoid to broadly fusoid with narrow ends, reddish brown with paler end cells, 8-septate, constricted at the primary septum, smooth-walled (Fig. 33e, f, g, h and i). Anamorph: Zalerion sp. (Tanaka and Harada 2003a). Material examined: BELGIUM, Beaufays, on cut off, still hard wood. Oct. 1922, V. Mouton (BR, Capsa: K 7534,
