039F1A75FFB7BB2DFF34FD8B6AFDE205.taxon	etymology	Etymology: names after the smooth apothecial margin. Type: — CHINA. Yunnan: Kunming City, — Qinglongxia (Yu’an mt.), Anning city, 1926 m, N 25 ° 03 ’ E 102 ° 22 ’, on bark and wood of Quercus, 3. XI. 2004, Z. F. Yu (qlx- 1, H. B. 7667, without culture) holotype H. B. 7667, deposited in M (Botanische Staatssammlung München, Germany). Apothecia sessile, gregarious, superficial, 0.3 – 1.2 mm in diam., smooth, plane, translucent, light coloured, pale pink to whitish when fresh, with an even margin or sometimes with prominent broad teeth 25 – 30 × 60 – 80 μm, 12 – 14 per apothecium, darker and irregularly undulating and concave when dry. Asci 8 - spored, 23 – 28 (– 32) × 3.4 – 3.6 μm (living state), 20 – 27 × (2.5 –) 2.9 – 3.1 (– 3.2) μm (dead state), cylindric-clavate, usually tapered below and forked at the base, with a truncate to rounded apex. Ascospores hyaline, non-septate, symmetrically crossed in the ascus, distinctly helicoidally twisted, with a broad, acute upper and a tapered lower end, (6 –) 7 – 8 (– 9) × 0.7 – 1 μm, bearing a tear-shaped refractive spore body (SB) at the upper end, 1.8 – 2.2 × 0.3 – 0.5 μm, fully filling the apex of the ascospore. Paraphyses hyaline, not or only slightly enlarged at the apex (2 – 3.2 μm in diam.), the apex being immersed in a 0.2 – 0.5 μm thick exudate. Ectal excipulum composed of angular or subangular cells, with thin or only slightly thickened walls of 5 – 14 μm in diam. 13 – 22 × 11 – 17 μm, at the upper margin of elongated cells oriented at a low angle to the surface, sometimes terminated by 1.5 – 2.5 μm long glassy processes. Colonies on CMA whitish, growing slowly, reaching 28 mm at 25 º after 10 days. Mycelium spreading, scanty, vegetative hyphae hyaline, septate, branched, 5.0 – 6.3 μm wide, often forming spirally coiled rings. Conidiophores hyaline, erect, more or less branched, septate, originating from both prostrate and aerial mycelium, 41 – 50 μm long, 3 – 4.3 μm wide at the base, tapering gradually upward to 1.3 – 1.6 μm at the tip, here bearing 1 – 10 denticles about 2 – 5 μm long and 1.3 – 1.6 μm wide, each with a single conidium to form capitate arrangements, occasionally proliferating to form additional clusters. Conidia cylindric-ellipsoid to oblong, broadly rounded at the distal end, tapered at the proximal end, partly with a definite pedicle, 10.2 – 13 × 3.0 – 4.0 μm (YMF 1.01833), 7.6 – 12.5 × 3.0 – 4.0 μm (YMF 1.01869) and 8.2 – 12.2 × 2.3 – 4.0 μm (YMF 1.03013), (0 –) 1 (– 3) - septate, the proximal cell 5.4 – 7.8 μm long with a ratio of approximately 1: 1 to the distal cell, occasionally constricted at the septum, containing several small LBs. Trapping devices were not observed when nematodes were added. Chlamydospores were not observed.
