Fungal Diversity cells from front view. Hamathecium of non-typical trabeculate pseudoparaphyses, 1–2 μm broad, septate, rarely branching, anastomosing not observed. Asci 410–505×(38-) 43–50 μm (x ¼ 470:6 46:4mm, n=10), 8-spored, bitunicate, fissitunicate dehiscence not observed, cylindrical, with a thick pedicel which is up to 90 μm long, and with a large and conspicuous dome-shaped ocular chamber surrounded by apical ring (to 18 μm wide×4 μm high) (Fig. 86b and e). Ascospores 53–65×30–38 μm (x ¼ 61:3 34:1mm, n=10), uniseriate to obliquely uniseriate and partially overlapping, broad fusoid to subglobose, hyaline when young, then becoming yellowish brown, reddish brown Fig. 85 Salsuginea ramicola (from BRIP 17102, holotype). a Habitat section of an ascoma. b Section of the partial peridium. c Clavate mature and immature asci. d Ascospores within ascus. e Apical part of immature asci. f Ascospores with an apical chamber at each end. Scale bars: a=0.5 mm, b–e=50 μm, f=10μm
Fungal Diversity and nearly black and opaque when mature, non-septate, smooth-walled, with a full length germ slit, surrounded by a broad gelatinous sheath (Fig. 86c and d). Anamorph: none reported. Material examined: CANADA, Alberta, North of Beaver Mines, on sheep dung, 28 Jul. 1962, E.R. Luck- Allen, (TRTC 41607, paratype); USA, Montana: Gallatin County, 60 min S of Bozeman, on sheep dung, 2 Sept. 1957, Cain (TRTC 42032, paratype); Stillwater County Columbus, on cow dung, 3 Sept. 1957, Cain (TRTC 42031, paratype); South Dakota, Meade Co.: South of Wall, on cow dung, 3 Sept. 1962, Cain (TRTC 40697, holotype). Notes Morphology Semidelitschia was formally establishedbyCainandLuck- Allen (1969) and was assigned to Sporormiaceae. Although it is similar to Delitschia, it differs as the ascospores are 1- celled, as opposed to 2-celled. Subsequently, Semidelitschia was transferred to Delitschiaceae together with Delitschia (Barr 2000). Currently, three species are listed under this genus, i.e. S. agasmatica Cain & Luck-Allen, S. nanostellata A.E. Bell & Mahoney and S. tetraspora J.H. Mirza & S.M. Khan (Index Fungorum) although the number of species in the genus are given as only two in Kirk et al. (2008). Phylogenetic study None. Concluding remarks This is a clearly defined genus that differs from Delitschia in having 1-celled ascospores. Cultures of S. agasmatica are needed for sequencing and for establishing the placement and uniqueness of the genus. Setomelanomma M. Morelet, Bull. Soc. Sci. nat. Arch. Toulon et du Var 227:15 (1980). (Phaeosphaeriaceae) Generic description Habitat terrestrial, hemibiotrophic or biotrophic. Ascomata small, solitary, scattered, immersed, erumpent to superficial, globose to subglobose, black; with or without a small papilla, apex covered with setae and a periphysate ostiole. Peridium thin, 1-layered, composed of several layers of cells of textura angularis. Hamathecium of dense, 1–2 μm broad pseudoparaphyses, septate, anastomosing. Asci 8- spored, bitunicate, broadly cylindrical. Ascospores fusoid to broadly clavate, pale brown to brown, 3-septate. Anamorphs reported for genus: none. Literature: Leonard and Suggs 1974; Morelet 1980; Rossman et al. 2002; Schochetal.2009; Zhang et al. 2009a. Type species Setomelanomma holmii M. Morelet, Bulletin de la Société des Sciences naturelles et d’Archéologie de Toulon et du Var 36 (no. 227): 15 (1980). (Fig. 87) (Some information in the following description is from Rossman et al. (2002)) Ascomata 80–250 μm diam., solitary, scattered, immersed, erumpent to superficial, globose to subglobose, black, with setae; with or without a small papilla, apex covered with setae and a periphysate ostiole. Peridium 15– 25 μm thick, 1-layered, composed of several layers of cells of textura angularis, cell wall thinner and more lightly pigmented towards centrum, cell wall thicker near the apex. Hamathecium of dense, 1–2 μm broad pseudoparaphyses, thicker near the base, septate, anastomosing (Fig. 87a and d). Asci 70–100×11–14 μm, 8-spored, bitunicate, broadly cylindrical with a short, thick, furcate pedicel, with a small ocular chamber (Fig. 87a, b and c). Ascospores 16–21×5– 6.5 μm, obliquely uniseriate and partially overlapping to biseriate, fusoid to broadly clavate with broadly to narrowly rounded ends, pale brown to brown, 3-septate, slightly constricted at the median septum, smooth (Fig. 87e). Anamorph: none reported. Material examined: FRANCE, Leuglay, on dying twigs of Picea pungens. 8 May 1987, leg. M. Morelet (UPS F- 117969 (slide), isotype). Notes Morphology Setomelanomma was formally established by Morelet (1980) as a monotypic genus represented by S. holmii, which was collected in France. The description, however, is not detailed and lacks illustrations. Rossman et al. (2002) collected this species in North America and detailed studies were conducted including both morphology and phylogeny. The bitunicate, broadly cylindrical asci, cellular pseudoparaphyses as well as the pale brown, septate ascospores with a median primary septum point Setomelanomma to Phaeosphaeriaceae as defined by Barr (1992a) and Eriksson et al. (2002) (Rossman et al. 2002). However, its setose ascomata, brown and 3-septate ascospores together with its residence in conifers distinguish it from all other genera under Phaeosphaeriaceae (Rossman et al. 2002). Setomelanomma is mostly comparable with Kalmusia and Phaeosphaeria. Setomelanomma can be distinguished from Kalmusia by its erumpent to superficial ascomata with almost no papilla, and Phaeosphaeria differs from Setomelanomma by its host spectrum and reported anamorphic stages (Rossman et al. 2002). Currently, five species are included in Setomelanomma, namely S. holmii, S. monoceras, S. prolata K.J. Leonard & Suggs, S. rostrata (K.J. Leonard) K.
