Type species Hadrospora fallax (Mouton) Boise, Mem. N. Y. bot. Gdn 49: 310 (1989).

Note the peridium structure. c Section of a partial peridium. Note the pseudoparenchymatous cells. d Asci in pseudoparaphyses. e–i Reddish brown multiseptate ascospores. Scale bars: a = 0.5 mm, b = 100 μm, c, d = 50 μm, e–i = 20 μm ≡ Trematosphaeria

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 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 SSR128129E cellular pseudoparaphyses, 1–2 μm broad, embedded in mucilage. JQEZ5 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).
