Fungal Diversity Fig. 65 Neomassariosphaeria typhicola (from IFRD 2018). a Immersed ascomata gregarious in the host substrate. b–d Cylindro-clavate asci embedded in pseudoparaphyses. Note the phragmosporous ascospores. Scale bars: a=200 μm, b–d=20 μm Generic description Habitat terrestrial, parasitic or saprobic. Ascomata small, forming in leaf spots, scattered or clustered, immersed, depressed globose, under clypeus, coriaceous. Peridium thin. Hamathecium of dense, cellular pseudoparaphyses, septate, embedded in mucilage. Asci 8-spored, bitunicate, fissitunicate dehiscence not observed, broadly cylindrical to oblong, with a short furcate pedicel. Ascospores obliquely uniseriate and partially overlapping, oblong, pale brown, 1-3-septate. Anamorphs reported for genus: Coniothyrium-like (Câmara et al. 2003). Literature: Câmara et al. 2001, 2003; Checa et al. 2002; Ellis and Everhart 1892.
Fungal Diversity Type species Neophaeosphaeria filamentosa (Ellis & Everh.) M.P.S. Câmara, M.E. Palm & A.W. Ramaley, Mycol. Res. 107: 519 (2003). (Fig. 66) ≡ Leptosphaeria filamentosa Ellis & Everh., J. Mycol. 4: 64 (1888). Ascomata 115–157 μm high×115–186 μm diam., forming in leaf spots, scattered or clustered in circular areas, immersed, depressed globose, with a small ostiolar pore slightly penetrating above the surface, under clypeus, coriaceous, papilla not conspicuous (Fig. 66a). Peridium 18–30 μm thick, composed of large pigmented thin-walled cells of textura angularis, cells up to 10 μm diam. (Fig. 66c). Hamathecium of dense, cellular pseudoparaphyses 1.5–2.5 μm broad, septate, embedded in mucilage (Fig. 66b). Asci 70–105×8– 10 μm (x ¼ 85:3 9:7mm, n=10), 8-spored, bitunicate, fissitunicate dehiscence not observed, broadly cylindrical to oblong, with a short, broad, furcate pedicel, 6–13 μm long, with a small ocular chamber, best seen in immature asci, up to 1.5 μm wide×1 μm high (Fig. 66d, e and f). Ascospores 12– 15×4–5 μm (x ¼ 13:8 5mm, n=10), obliquely uniseriate and partially overlapping, oblong, yellowish brown, (1-2-)3- septate, constricted at the primary septum, the upper second cell often broader than others, verruculose, containing four refractive globules (Fig. 66g). Anamorph: Ellis and Everhart (1892) noted that the “spermogonial stage is a Coniothyrium (C. concentricum) with small (4 μm), globose, brown sporidia.” Material examined: USA, New Jersey, Newfield, on dead parts in living leaves of Yucca filamentosa L., Jul. 1888, Ellis & Everhart (NY, holotype). Notes Morphology Neophaeosphaeria was formally established by Câmara et al. (2003) by segregating Paraphaeosphaeria species with 3-4-septate ascospores and anamorphs of ovoid to ellipsoid, non-septate, brown, verrucose to punctuate conidia forming from percurrently proliferating conidiogenous cells. Neophaeosphaeria filamentosa was selected as the generic type. Currently, four species are included under Neophaeosphaeria, i.e. N. barrii, N. conglomerate (M.E. Barr) M.P.S. Câmara, M.E. Palm & A.W. Ramaley, N. filamentosa and N. quadriseptata (M. E. Barr) M.P.S. Câmara, M.E. Palm & A.W. Ramaley (Câmara et al. 2003). At present all species in Neophaeosphaeria occur on Yucca (Agavaceae). Phylogenetic study The four Neophaeosphaeria species form a monophyletic clade based on both ITS and SSU rDNA sequences (Câmara et al. 2001; Checa et al. 2002), and they fall in the group comprising members of Phaeosphaeriaceae and Leptosphaeriaceae (Câmara et al. 2003). Neophaeosphaeria filamentosa, the generic type of Neophaeosphaeria, nestedinLeptosphaeriaceae with low to moderate bootstrap values (Schoch et al. 2009; Zhang et al. 2009a). Concluding remarks The familial status of Neophaeosphaeria under Leptosphaeriaceae is confirmed, although this family remains poorly supported in phylogenetic studies. Nodulosphaeria Rabenh., Klotzschii Herb. Viv. Mycol., Edn 2: no. 725 (in sched.) (1858). (Phaeosphaeriaceae) Generic description Habitat terrestrial, saprobic or hemibiotrophic. Ascomata small, immersed to erumpent, globose or subglobose, black, papillate, ostiolate. Papilla with numerous setae in the pore-like ostiole. Peridium thin, composed of thickor thin-walled large cells. Hamathecium of cellular pseudoparaphyses, septate and branching. Asci 8- spored, bitunicate, fissitunicate, clavate to cylindroclavate, with a very short, furcate pedicel and a small ocular chamber. Ascospores filamentous, hyaline or pale brown, multi-septate, one of the upper cells swollen. Anamorphs reported for genus: none. Literature: Barr 1992a; Holm 1957, 1961; Shoemaker 1984b; Shoemaker and Babcock 1987. Type species Nodulosphaeria hirta Rabenh., Klotzschii Herb. Viv. Mycol., Edn 2: no. 725 (in sched.) (1858). (Fig. 67) Ascomata 260–330 μm high×260–330 μm diam., scattered, or in small groups, immersed to erumpent, globose or subglobose, black, papillate, ostiolate. Papilla 50–80 μm high, numerous setae occur in the pore-like ostiole (Fig. 67a and b). Peridium 15–30 μm wide at the sides, thinner at the base, coriaceous, comprising two types of cells, outer cells of 1–2 layers of heavily pigmented cells of textura angularis, cells 6–8 μm diam., cell wall 1.5– 3 μm thick, inner of compressed cells, 5×13–3×8 μm diam., wall 2–3 μm thick (Fig. 67c). Hamathecium of long cellular pseudoparaphyses 2–3 μm broad, septate and branching, mucilage not observed. Asci 100–123×12.5–15 (−17.5) μm (x ¼ 110:8 14:3mm, n=10), 8-spored, bitunicate, fissitunicate, clavate to cylindro-clavate, with a very short, furcate pedicel, with a small ocular chamber (to 2 μm wide×1 μm high) (Fig. 67d). Ascospores 48–63×5–6.5 μm (x ¼ 55:3 5:6mm, n=10), 4-seriate, filamentous, pale
