Fig. 4
Teleomorph.
Stromata upright, solitary or sometimes clustered, unbranched or occasionally branched, 1.2–8.0 cm total height; fertile parts 6–25 mm high × 1.5–5.0 mm broad, cylindrical with acute sterile apices, at times longitudinally furrowed, with wrinkles isolating somewhat prominent perithecia; stipes 6–55 mm high × 1.0– 2.5 mm broad, glabrous to pubescent arising from a pannose base; surface dark brown to black, interior white, with dark brown to black a circle, and white at center. Texture solid, soft, woody. Perithecia subglobose, 250–400 µm. Ostioles conic-papillate. Asci eight-spored arranged in uniseriate manner, cylindrical, long-stipitate, (110 –) 125–145 (– 165) µm total length, the spore-bearing parts (80 –) 90–105 (– 115) µm long × (6 –) 7–8 (– 8.5) µm broad, the stipes 30–60 µm long, with apical ring bluing in Melzer’s reagent, inverted hap-shaped to more or less rectangular, 2.5–3.5 µm high × 2.0–2.5 µm diam. Ascospores brown, unicellular, ellipsoid-inequilateral with narrowly to broadly rounded ends, smooth, (12.5 –) 13–14 (– 15) × (4.8 –) 5.5–6.5 (– 6.8) µm (M = 13.5 × 6.1 µm, Q = 2.2, n = 90 / 3), with spiraling germ slit, lacking a sheath or appendages in india ink or 1 % SDS.

Notes.
Xylaria liquidambaris was originally described by Rogers et al. (2002) from USA, and has high specificity to fruits of Liquidambar (Altingiaceae). It is characterized by unbranched stromata with acute sterile apex, embedded to slightly prominent perithecia with longitudinal striations, brown ascospores with long spiraling germ slit (Rogers et al. 2002). These Chinese materials well fit the descriptions and illustrations of X. liquidambaris by Rogers et al. (2002).
