Sarcpscypha mesocyatha F.A. Harr. Harvard Papers in Botany 1 (10): 62, 1997. Fig. 2 D− G

Apothecia scattered, discoid, small, 8−10 mm diam., sessile to subsessile. Disc concave to flat, Scarlet Red to Peach Red (Ridgway), margin slightly raised, inrolled when dry. Receptacle whitish with a red tint, contracted below, sparsely covered by short hyphal hairs, base with white subiculum. Asci 8-spored, J-, cylindrical, 275−280 × 10−12 μm, base attenuated into a long stalk, without croziers. Ascospores uniseriate, ellipsoid with depressions at two ends, smooth, 20−25 × 9−12 μm, containing 2−3 large guttules when fresh. Paraphyses filiform, slightly exceeding the asci, apex 3−4 μm wide, sparsely septate. Conidia not seen.

Specimens examined: — TAIWAN. Miaoli: Kuanwu-Hsuehchieh , elev. 1900 m, on dead twigs, 2 September 1995, C.A. Chiu ; CCA 23 ( TNM F3688 ). Nantou, Tungpu, on dead branches, 10 August 1995, W.N. Chou, WAN 189 ( TNM F3460 ). Nantou, Wushe , on dead twigs, elev. 870 m, 4 July 1996, W.N. Chou, WAN 309 ( TNM F5134 ) .

Notes:— This species was originally reported from Hawaii, which is characterized by small to medium-sized apothecia, and ascospores with deep depressions at both ends ( Harrington 1997; Zhuang 2000). The ascospores of these specimens are slightly smaller than those in the holotype (21−27 × 9−10.5 μm, Harrington, 1997). It is a new record to the Taiwanese fungal flora.
