Concluding remarks Westerdykella is another example where ascospore ornamentation can be phylogenetically uninformative. Westerdykella is proved a good genus
of Sporormiaceae (Kruys and Wedin 2009). Wettsteinina Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. I 116: 126 (1907). (?Lentitheciaceae) Generic description Habitat terrestrial or freshwater? hemibiotrophic or saprobic. Ascomata generally small, scattered, immersed with a protruding broad papilla. Peridium very thin, composed of few layers of thin-walled large polygonal cells in surface view. Hamathecium JNK-IN-8 deliquescing at maturity. Asci bitunicate, fissitunicate, subglobose to obpyriform, without a pedicel, with small truncate ocular chamber. Ascospores hyaline and turning pale brown AC220 mouse when mature,
septate, upper second cell enlarged, slightly constricted at the second septum, smooth, surrounded by a hyaline gelatinous sheath. Anamorph reported for genus: Stagonospora (Farr et al. 1989). Literature: Barr 1972; Müller 1950; Shoemaker and Babcock 1987, 1989b. Type species Wettsteinina gigaspora Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 116: 126 (1907). (Fig. 95) Fig. 95 Wettsteinina gigantospora (from S, holotype of Massarina gigantospora). a Ascomata with protruding papilla scattered on the host surface. b Obpyriform thick-walled ascus with small apical apparatus. c Fissitunicate ascus. d Released hyaline ascospores. Note the distinct primary septum and less distinct secondary septa. e Ascospore with sheath. Scale bars: a = 0.5 mm, b–d = 100 μm, e = 50 μm Ascomata 150–250 μm diam., scattered, immersed with protruding broad BIX 1294 cell line papillae, 50–90 μm diam. Peridium thin, composed of
few layers of thin-walled large polygonal cells in surface view, 6–15 μm diam. (Fig. 95a). Hamathecium deliquescing at maturity. Asci 140–200 × 75–120 μm, 8-spored, bitunicate, fissitunicate, subglobose to obpyriform, lacking a pedicel, with a small truncate ocular chamber (to 8 μm wide × 5 μm high) (Fig. 95b and c). Ascospores 90–110 × 25–30 μm, 2–4-seriate, hyaline and turning pale brown when mature, broadly clavate, 4-septate, primary septum distinct and constricted forming 1/3rd from the apex of the ascospore, complete, secondary septa less distinct and slightly constricted, incomplete, with one forming above Resveratrol and two forming below the primary septum, largest cell the second cell from apex, smooth, surrounded by a hyaline gelatinous sheath 5–8 μm thick (Fig. 95d and e). Anamorph: none reported. Material examined: SLOVENIA, Postojna, on Genista sagittalis leg. Stapf. det. H. Rehm. (S, holotype of Massarina gigantospora). Notes Morphology Confusion exists in the generic type of Wettsteinina. Höhnel (1907) described W. gigaspora when introducing Wettsteinina, and listed it as the first species of Wettsteinina. Clements and Shear (1931) accepted W.
