51) and Indonesia (CBS 317.83) resided within Didymellaceae (de Gruyter et al. 2009; Zhang et al. 2009a). Concluding remarks Because of its morphological confusion with Pleospora

and the diversity of habitats within the genus, Leptosphaerulina sensu lato is likely to be polyphyletic. Fresh collections of this species are needed from Australia to epitypify this taxon and define the genus in a strict sense. The specimen described here is a collection from USA and therefore may not represent the type. Lewia M.E. Barr & E.G. Simmons, Mycotaxon 25: 289 (1986). (Pleosporaceae) Generic description Habitat terrestrial, parasitic or saprobic? Ascomata small, scattered, erumpent to nearly superficial at maturity, subglobose to globose, black, smooth, papillate, ostiolate. selleck kinase inhibitor Papilla short, blunt. Peridium thin. Hamathecium

of pseudoparaphyses. Asci (4–6-)8-spored, bitunicate, fissitunicate, cylindrical to cylindro-clavate, with a short, furcate pedicel. Ascospores muriform, ellipsoid to fusoid. Anamorphs reported for genus: Alternaria (Simmons 1986). Literature: Kwasna and Kosiak 2003; Kwasna et al. 2006; Simmons 1986, 2007; Vieira and Barreto 2006.

Scale bars: a = 20 μm, b–f = 10 μm ≡ Sphaeria scrophulariae Desm., Plantes cryptogames du Nord de la France, ed. 1 fasc. 15:no. 718 (1834). Ascomata ca. 150–200 μm diam., scattered, erumpent to nearly superficial at maturity, subglobose to globose, black, smooth, papillate. Papilla short, blunt. Peridium thin. Hamathecium of septate pseudoparaphyses, ca. 2–2.5 μm broad,

anastomosing or branching not observed. Asci 100–140 × 13–17 μm, (4–6-)8-spored, bitunicate, fissitunicate, cylindrical to cylindro-clavate, with a short, furcate pedicel, ocular chamber unknown (Fig. 46a). Ascospores ellipsoid, 5 (rarely 6 or 7) transversal septa and one longitudinal septum mostly through the central cells, yellowish brown to gold-brown, 20–24 × 8–10 μm (\( \barx = 21.5 \times 9.1\mu m \), n = 10), constricted at median septum, smooth or verruculose (Fig. 46b, e and f). Anamorph: Alternaria conjuncta (Simmons 1986). Primary conidiophore simple with a single conidiogenous locus; conidia produced in chains, the first conidia in chain is larger, 30–45 × 10–12 μm, 7 transverse septa, 1–2 longitudinal or oblique septa in lower cells. Secondary conidiophore with 5–7 conidiogenous loci, selleck screening library sometimes branched; sporulation in chains, rarely branched. Material examined: (FH, slide from lectotype). Note: The specimen contains only a slide, so limited structures could be observed e.g. ascospores.
