Fungal Diversity Fig. 12 2 (continued) 400×22–40 μm, 8-spored, bitunicate, fissitunicate, cylindrical, with long pedicels and apical apparatus (Fig. 12.1a, b, 2b). Ascospores 55–82×16–25 μm, uniseriate to partially overlapping, fusoid, hyaline when young, becoming brown to dark brown at maturity, 2-4-septate towards each end, and with a hyaline, globose refractive chamber or appendage at each end, 6–8×4–6 μm diam., not constricted at the septum (Fig. 12.1c, d, 2c).
Fungal Diversity Anamorph: none reported. Material examined: SEYCHELLES, 2 Jan. 1984 (Herb. IMI 297768 holotype). Notes Morphology Biatriospora was introduced to accommodate a marine fungus B. marina, which is characterized by horizontal ascomata and ascospores with polar, globose refractive chambers and polar septa (Hyde and Borse 1986). Polar refractive chambers can also occur in other marine fungi, such as Lulworthia and Aigialus. The chambers have been proposed as important for spore attachment to substrates in a liquid environment (Hyde and Borse 1986). Phylogenetic study Multigene phylogenetic analysis indicated that Biatriospora marina forms a separate branch, sister to other families of <strong>Pleosporales</strong> (Suetrong et al. 2009), and maybe related to species in Roussoella (Plate 1). Concluding remarks The familial status of Biatriospora can not be determined. Bicrouania Kohlm. & Volkm.-Kohlm., Mycol. Res. 94: 685 (1990). (?Melanommataceae) Generic description Habitat marine, saprobic. Ascomata immersed gregarious, erumpent to superficial, globose to subglobose, black, periphysate, coriaceous, epapillate or papillate, ostiolate. Peridium thin, 2-layered. Hamathecium of dense, long trabeculate pseudoparaphyses, branching and anastomosing between and above the asci. Asci 8-spored, bitunicate, fissitunicate, cylindrical, with a thick, furcate pedicel lacking ocular chamber. Ascospores obliquely uniseriate and partially overlapping, ellipsoidal with broadly rounded ends, reddish brown, 1-septate, thick-walled, constricted at the septum. Anamorphs reported for genus: none. Literature: Jones et al. 2009; Kohlmeyer and Volkmann- Kohlmeyer 1990. Type species Bicrouania maritima (P. Crouan & H. Crouan) Kohlm. & Volkm.-Kohlm., Mycol. Res. 94: 685 (1990). (Fig. 13) ≡ Sphaeria maritima P. Crouan & H. Crouan, Florule du Finistére, Paris: 27 (1867) non Sphaeria maritima Cooke & Plowright, Grevillia 5: 120 (1877). Ascomata 320–440 μm high×370–460 μm diam., gregarious, immersed, mostly erumpent to superficial, globose to subglobose, black, coriaceous, with a rough surface, papillate or epapillate, ostiolate, periphysate (Fig. 13a). Peridium 40–50 μm thick laterally, up to 75 μm thick at the apex, thinner at the base, 2-layered, outer layer composed of small heavily pigmented pseudoparenchymatous cells, inner layer very thin, composed of hyaline thin-walled small cells, merging into pseudoparaphyses (Fig. 13a and b). Hamathecium of dense, very long trabeculate pseudoparaphyses, 0.8– 1.2 μm broad, branching and anastomosing between and above the asci. Asci 170–225×17.5–22.5 μm (x ¼ 199:6 20mm, n=10), 8-spored, bitunicate, fissitunicate, cylindrical, with a thick, furcate pedicel which is up to 70 μm long, lacking ocular chamber (Fig. 13c, d and e). Ascospores 22–26×12–15 μm (x ¼ 24:5 13:3mm, n= 10), obliquely uniseriate and partially overlapping, ellipsoidal with broadly rounded ends, reddish brown, 1- septate, slightly constricted at the septum, thick-walled, with a thick darkened band around the septum, smooth (Fig. 13c, d and e). Anamorph: none reported. Material examined: FRANCE, Finistère, on Halimone portulacoides (IMI 330806, isotype, as Sphaeria maritima). Notes Morphology When Kohlmeyer and Volkmann-Kohlmeyer (1990) studied the four marine Didymosphaeria species, the monotypic Bicrouania was established to accommodate B. maritima (as Didymosphaeria maritima (P. Crouan & H. Crouan) Sacc.), which could be distinguished from Didymosphaeria by its superficial ascomata lacking a clypeus, thick-walled asci and its association with algae (Kohlmeyer and Volkmann- Kohlmeyer 1990). Jones et al. (2009) agreed that it cannot be placed in Didymosphaeria based on its superficial ascomata, but that it does have many similarities with Didymosphaeria. Molecular data are required to determine its relationship with Didymosphaeria and to resolve its higher level placement. Phylogenetic study None. Concluding remarks Besides the morphological differences, its marine and substrate habitats also differ from Didymosphaeria. Bimuria D. Hawksw., Chea & Sheridan, N. Z. J. Bot. 17: 268 (1979).
