Asci 8-spored, bitunicate, fissitunicate unknown, cylindrical with a furcate pedicel and a large ocular

chamber. Ascospores fusoid or narrowly fusoid, brown or reddish brown, 3-septate, constricted at each septum. Anamorphs reported for genus: Coniothyrium and Phoma (Hyde et al. 2011; Sivanesan 1984).

Soc. crittog. Ital. 1: 234 (1863). (Fig. 44) Fig. 44 Leptosphaeria doliolum (from L, lectotype). a Ascomata on the host surface. Note the shiny black surface. b Section of the partial peridium. Note the uneven thickness. c–e Asci with a short pedicel. f Three ascospores in ascus. Scale bars: a = 0.5 mm, b = 100 μm, c–f = 20 μm ≡ Sphaeria doliolum Pers., Icon. Desc. Fung. Min. Cognit. (Leipzig) 2: 39 (1800). Ascomata 340–450 μm high × 380–500 μm diam., solitary, scattered or in small groups, superficial, subglobose, broadly or narrowly conical, with a flattened base on the host surface, black, usually with 2–4 ring-like ridges surrounding the ascomata surface, apex with a conical, usually shiny papilla (Fig. 44a). Peridium 85–110 μm wide FK228 cell line at sides, thinner at the apex, comprising two types of cells, outer layer composed of small thick-walled cells of textura angularis, cells <2 μm diam., cell wall up to 8 μm thick, surface heavily pigmented and inner lightly

pigmented, apex cells smaller, walls thicker, and cells more heavily pigmented, inner layer composed of subhyaline relatively thin-walled cells of textura angularis, 3–6 μm diam., wall up to 5 μm, cells near the Tacrolimus (FK506) base larger and wall thinner and paler (Fig. 44b). Hamathecium of dense, long cellular pseudoparaphyses, 1.5–3 μm broad, embedded in mucilage, anastomosing and branching. Asci 110–150 × 7–9(−10) μm (\( \barx = 130.6 \times 8.5\mu m \), n = 10), 8-spored, bitunicate, fissitunicate unknown, cylindrical, furcate pedicel which is usually less than 25 μm long, with a large ocular chamber (Fig. 44c, d and e). Ascospores 25–31 × 4.5–6 μm (\( \barx = 27.7 \times 5.3\mu m \), n = 10), uniseriate and somewhat partially overlapping, narrowly fusoid with sharp to narrowly rounded ends, reddish brown, 3-septate, constricted at each septum, smooth (Fig. 44f). Anamorph: Phoma hoehnelii (Sivanesan 1984). Material examined: Herb., Persoon 910270–650 (L, lectotype). Notes Morphology Leptosphaeria was first established by Cesati and de Notaris (1863) with 26 species included; L. doliolum (Pers.:Fr.) Ces. & De Not.
