Peridium thin, comprising pseudoparenchymatous cells Hamathecium

Peridium thin, comprising pseudoparenchymatous cells. Hamathecium dense, Selleckchem SB-715992 narrowly cellular, embedded in mucilage. Asci bitunicate, fissitunicate, oblong to ovoid, with a short pedicel. Ascospores ellipsoid to broadly fusoid with narrow ends, reddish brown, multi-septate, constricted at the primary septum. Anamorphs reported

for genus: Zalerion (Tanaka and Harada 2003a). Literature: Boise 1984, 1989; Fisher and Webster 1992; Shearer and Crane 1971; Tanaka and Harada 2003a; Webster 1993. Type species Hadrospora fallax (Mouton) Boise, Mem. N. Y. bot. Gdn 49: 310 (1989).

fallax Mouton, Bull. Soc. R. Bot. Belg. 25: 155, (1886). Ascomata 130–240 μm high × 200–330 μm diam., solitary, scattered or in groups, initially immersed, becoming erumpent to nearly superficial, with basal wall remaining immersed in host tissue, not easily removed from the find more substrate, globose or subglobose, roughened, papillate, coriaceous (Fig. 33a). Peridium 30–45 μm wide, comprising cells of pseudoparenchymatous, up to 12.5 × 9 μm diam. (Fig. 33b and c). Hamathecium of dense, narrowly Monoiodotyrosine cellular pseudoparaphyses, 1–2 μm broad, embedded in mucilage. click here Asci 150–200 × 40–60 μm (\( \barx = 171.5 \times 48\mu m \), n = 10), 8-spored, bitunicate, fissitunicate, oblong to ovoid, with a short pedicel, 10–24 μm long, with a ocular chamber (to 5 μm wide × 6 μm high) (Fig. 33d). Ascospores 55–80 × 16–22 μm (\( \barx = 67.1 \times 18.1\mu m \), n = 10), biseriate to 4-seriate, ellipsoid to broadly fusoid with narrow ends, reddish

brown with paler end cells, 8-septate, constricted at the primary septum, smooth-walled (Fig. 33e, f, g, h and i). Anamorph: Zalerion sp. (Tanaka and Harada 2003a). Material examined: BELGIUM, Beaufays, on cut off, still hard wood. Oct. 1922, V. Mouton (BR, Capsa: K 7534, holotype). (Note: The specimen is not in good condition, only a few ascomata left). Notes Morphology Boise (1989) formally established Hadrospora to accommodate Trematosphaeria fallax and T. clarkia (Sivan.) Boise, and Hadrospora fallax (syn. T. fallax) was selected as the generic type. Hadrospora is a widely distributed species that has been reported from Belgium, China, Italy, Japan, Switzerland and the United States (Boise 1989; Fisher and Webster 1992; Shearer and Crane 1971; Tanaka and Harada 2003a; Webster 1993).
