96a and b). Peridium 6–15 μm wide, 1-layered, composed of 3–7 layers of brown, thick-walled cells of textura angularis to prismatica, cells 4–9 μm diam., cell wall 2–4 μm thick (Fig. 96a and b). Hamathecium of long cellular pseudoparaphyses 2–3 μm broad, septate, rarely branching, embedded in mucilage, evanescent. Asci 65–95 × 9.5–14 μm

(\( \barx = 78.5 \times 11.5 \mu \textm \), n = 10), 8-spored, bitunicate, fissitunicate, cylindrical to clavate, with a short, furcate pedicel and a small ocular chamber (Fig. 96c, d and f). Ascospores 22.5–28 × 5–8.5 μm (\( \barx = 26.5 \times 6.8 \mu \textm \), n = 10), biseriate, fusoid with narrowly rounded ABT-199 manufacturer ends, pale brown, 1-septate, constricted at the septum, the upper cell often shorter and broader than the lower one, smooth, with or without sheath (Fig. 96d and e). Anamorph: Conidiomata 170–200 μm high × 85–130 μm diam., eustromatic, immersed, subglobose to irregular, ostiolate, brown. Peridium thin, 1–2 wall layers, 6–8 μm thick, thicker near the apex. Ostiole 50–63 μm high × 30–35 broad. Conidiogenous cells ampulliform or lageniform, phialidic, aseptate. Conidia 13–20 × 4–7 μm, ellipsoid, oblong, ovoid, hyaline (Dianese et al. 2001). Material examined: BRAZIL, Distrito Federal, Vargem Bonita, Fazenda Agua Limpa, on leaves of Memora pedunculata

Selleckchem Y-27632 (Vell.) Miers, 18 May 1995, Inositol monophosphatase 1 Carlos A. Inácio (UB Col. Microl 8438 holotype). Notes Morphology Wilmia was formally established by Dianese et al. (2001) as a monotypic genus represented by W. brasiliensis, which causes leaf spots on Memora pedunculata. The peridium of W. brasiliensis comprises a few layers of brown, thick-walled textura angularis to prismatica cells, and it also has cellular pseudoparaphyses, clavate asci, 1-septate pale brown ascospores (Dianese et al. 2001). Phylogenetic study None. Concluding remarks The dicotyledonous

host habit of Wilmia brasiliensis seems in agreement with Leptosphaeriaceae rather than Phaeosphaeriaceae. But a verified conclusion can only be reached by further molecular phylogenetic study. Xenolophium Syd., Bulletin of the Bernice P. Bishop Museum, Honolulu, Hawaii 19: 96 (1925). (Pleosporales, genera incertae sedis) Generic description Habitat terrestrial, saprobic on wood. Ascomata nearly superficial, scattered to gregarious, globose, large, with a conspicuous compressed papilla and large slit-like ostiole. Peridium carbonaceous. Hamathecium of dense, long trabeculate pseudoparaphyses, branching and anastomosing between and among asci. Asci 8-spored, clavate, with very long furcate pedicels. Ascospores fusoid to narrowly fusoid, light to dark brown, 1-septate, constricted at the septum. Anamorphs reported for genus: none.
