Sarcoscypha tatakensis Yei Z. Wang & C.L. Huang View in CoL , sp. nov. Figs. 5 View FIGURE 5 , 6 View FIGURE 6 .

MycoBank MB 814978.

Type:— TAIWAN, Nantou, Tataka , elev. 2730 m, on dead twigs, 10 March 1993, coll. J.M. Chen ; 93051915 (Holotype, TNM F0993 About TNM ) .

Apothecia scattered, cupulate to discoid, 5−20 mm diam., sessile to subsessile. Disc concave to flat, undulate, Scarlet Red when fresh, when drying becoming to Cadmium Yellow (Ridgway), margin entire, slightly raised, inrolled when dry. Receptacle paler, contracted below into a very short stalk attached to substrate, surface heavily wrinkled when dry, base with scanty white subiculum. External hairs scanty, sparsely distributed on receptacle, smooth, short, straight to flexuous, 2−3 μm wide. Ectal excipulum thin, 100−150 μm thick, Aniline Yellow (Ridgway), textura prismatica to textura porrecta, hyphae 3−5 μm wide, parallel to outer surface. Medullary excipulum 200−500 μm thick, white, of textura intricata, hyphae loosely arranged, 3−5 μm wide. Subhymenium layer 50−70 μm thick, yellowish, of dense textura intricata, hyphae 3–4 μm wide. Hymenium layer 300−325 μm thick. Asci 8-spored, J−, cylindrical, 260−325 × 10−13 μm, base attenuated into a long stalk, without croziers. Ascospores uniseriate, ellipsoid, with shallow depressions at both ends, smooth, (16−)21−27(−30) × 9−11(−14) μm, usually with 2−3 large guttules, 3−5 μm diam. when fresh. Paraphyses filiform, slightly exceeding the asci, 2−3 μm wide, sparsely septate, tips simple, filled with pigment vacuoles when fresh. Conidia not seen.

Etymology:—referring to the location of the holotype.

Additional specimen examined:— TAIWAN, Nantou, Tataka, elev. 2730 m, on dead twigs, 28 October 1992, coll. J.M. Chen, 93042903 (TNM F0754).

Notes:— The guttules inside the ascospores are vague in dried specimens, but re-appear after treating with KOH solution ( Fig. 6E View FIGURE 6 ). This species is closely related to S. knixoniana F.A. Harr. as having small to medium-sized apothecia, and similar shape of ascospores, however, the latter has stipitate apothecia and smaller ascospores ( Otani 1980; Harrington 1997).
