Type:— TAIWAN, New Taipei City, Beijishan , elev. 300 m, on fruit shell, 7 December 2014, J.L. Wei ; Wei 14-264 (Holotype, TNM F28831 About TNM ) .

Apothecia gregarious, cyathiform to cupuliform, small, 1−5 mm diam., stipitate. Disc concave, Orange to Cadmium Yellow (Ridgway), margin crenulate, raised, 100−200 μm high, inrolled when dry. Receptacle paler, contracted below into a short stalk; 1−2 mm high, glabrous, surface with short hyphae protrusions, base with creamy white subiculum, hyphae 3−5 μm wide. Ectal excipulum thin, 25−50 μm thick, textura prismatica to textura porrecta, hyphae 2−5 μm wide, yellowish, extending out as short protrusions. Medullary excipulum 250−300 μm thick, white, of loose textura intricata, hyphae 2−4 μm wide. Hymenium layer 250−300 μm thick. Asci 8-spored, J−, cylindrical, 180−250 × 7−10 μm, base without croziers. Ascospores uniseriate, broadly ellipsoid, smooth, (15−)16−20(−22) × (7−)8−10 μm, containing a large guttule when fresh. Paraphyses filiform, slightly exceeding the asci, 2−5 μm wide, sparsely septate, apex simple. Conidia not seen.

Etymology:—referring to the small apothecia.

Notes:— This species is characterized by the combination of very small apothecia, short asci and small ascospores with a large guttule. The closely related species, S. korfiana F.A. Harr. , also has small apothecia, but is with yellow hymenium, hairy stipe, and grows on woody substrates ( Zhuang 1993; Harrington 1997). Harrington (1997) cited a specimen of S. mesocyatha collected from the endocarp of a Myrsine species, however, it has larger ascospores with deep depression at both ends ( Zhuang 2000).
