Fig. 2 Index Fungorum number: 551515, Facesoffungi number: FoF 01055 Diagnosis:—Rabbit-ear shaped apothecia, with a tea brown to blackish brown hymenium, a red, reddish brown to greyish yellow receptacle surface, and a costate stipe. Paraphyses filiform 3–4 μm broad, and ascospores ellipsoid 19–23 × 10.5–12 μm. Etymology:— subalpina is proposed for its occurrence in subalpine regions in western China. Apothecia rabbit-ear shaped, 3–6 cm high, 1–4 cm broad, hymenium glabrous, tea brown to blackish brown, blackish brown when dry, margin rolled to hymenium when young, expanded at maturity; receptacle surface glabrous, red, reddish brown to greyish yellow, yellowish near the base. Stipe costate, glabrous, 0.5–1.5 × 0.5–2 cm, narrowing to base, light yellow to yellowish. Medullary excipulum 400–490 μm broad, of textura intricata, hyaline, composed of 2.5–5 μm broad hyphae, J-. Ectal excipulum 100–150 μm broad, of textura angularis, pale yellow, lightly encrusted with pale brown crystals, end cells 30–60 × 10–20 μm, J-. Asci arising from croziers, 8-spored, cylindrical to clavate, with apex rounded, 330–390 × 17–23 μm. Paraphyses filiform, 3–4 μm broad, brown, slightly short or exceeding the asci, hyaline in Melzer's reagent, light blue in cotton blue, enlarged apex 4–6 μm broad, J-. Ascospores [60/2/2, in H 2 O] 19–23 × 10.5–12 μm [Q = 1.32–1.58, Q = 1.47 ± 0.06)], ellipsoid, smooth-walled under the light microscope. Odor unique and strong when dried, but not detected when fresh. Habitat and distribution:—Solitary to scattered on the ground or moss, under Picea spp. forest. Only known from high altitude localities in western China. Typification:— CHINA. Tibet, Riwoqe County, on road (highway 317) from Riwoqe to Dingqing, 12 August 2004, Zhu L .
