Fungal Diversity Fig. 26 Delitschia didyma (from L, 1950). a Ascomata on the substrate surface. Note the ostiolar opening. b Section of peridium. Note the small cells of textura angularis. c Released and unreleased ascospores. Note the germ slit in each cell. d, e Asci with ascospores and short pedicels with rounded ends. Scale bars: a=0.5 mm, b =30 μm, c–e=70 μm Type species Didymosphaeria futilis (Berk. & Broome) Rehm, Hedwigia 18: 167 (1879). (Fig. 27) ≡ Sphaeria futilis Berk. & Broome, Ann. Mag. nat. Hist., Ser. 2 9: 326 (1852). Ascomata 190–230 μm high×240–340 μm diam., scattered, or in small groups, immersed to slightly erumpent, subglobose to ovoid, membraneous, near-hyaline, under clypeus, papillate, periphysate (Fig. 27a and c). Papilla central, up to 100 μm high, black, with a pore-like ostiole (Fig. 27a and c). Peridium 30–40 μm wide upper part, 6– 23 μm wide near the base, 1-layered, composed of brown pseudoparenchymatous cells of textura angularis, cell wall 2– 3 μm thick (Fig. 27b). Hamathecium of dense, long trabeculate pseudoparaphyses, 0.8–1.5 μm broad, anastomosing mostly above the asci, embedded in mucilage (Fig. 27d). Asci 90–110×7.5–10 μm (x ¼ 97 9mm, n=10), 2–4-spored, rarely 8-spored, bitunicate, fissitunicate, cylindrical, with a furcate pedicel, 17.5–27.5 μm long, with a large ocular (to 2.5 μm wide×4 μm high) (Fig. 27d, e and f). Ascospores 14– 15.5×(5.5-) 6–7.5 μm (x ¼ 14:8 6:9mm, n=10), uniseriate, ellipsoid with obtuse ends, brown, 1-septate, distoseptate, slightly to not constricted, capitate (Fig. 27g). Anamorph: Dendrophoma sp., Fusicladiella sp. vel aff. (Sivanesan 1984).
Fungal Diversity Material examined: UK, England, Norfolk, King’s Cliffe; on dead stem (in ramis emortuis) Rosa sp., Mar. 1850, M.J. Berkeley (K(M): 147683, holotype). Notes Morphology Didymosphaeria is a widely distributed genus with wide host range (Aptroot 1995). Didymosphaeria was formally established by Fuckel (1870) based on six ascomycetous species, and D. epidermidis (Fries) Fuckel (or D. peltigerae Fuckel) has been chosen as the lectotype species (see comments by Aptroot 1995). Hawksworth and David (1989: 494) proposed to conserve the genus with a lectotype specimen, Fungi Rhenani 1770. The genus had been considered as a depository to accommodate all types of didymosporous pyrenocarpous ascomycetes. Many workers have tried to redefine the genus and excluded some species. Saccardo (1882) restricted the genus to brown-spored species, and about 100 species have been excluded subsequently (Barr 1989a, b, 1990a, 1992a, b, 1993b; Hawksworth1985a, b; Hawksworth and Boise 1985; Hawksworth and Diederich Fig. 27 Didymosphaeria futilis (from K(M): 147683, holotype). a Two immersed ascomata on the host surface (one of them is cut horizontally). b Section of an ascoma. Note the thin peridium. c Hand cut portion of ascoma showing habitat in wood. d Asci in pseudoparaphyses. Note the trabeculate pseudonparaphyses anastomosing above the asci. e, f Four-spored asci with long pedicels which are rounded at their bases. g Brown, 1-septate ascospores with spinulose ornamentation. Scale bars: a=0.3 mm, b, c= 100 μm, d–g=10 μm
