Calloria auricolor (Bloxam ex Berk. & Broome) Phillips, Manual of British Discomycetes: 334. 1887.
Basionym: Mollisia auricolor Bloxam ex Berk. & Broome, Annals and Magazine of Natural History Series 3, 15: 346. 1865.
Description：
Apothecia gregarious, superficial, sessile, yellowish, translucent when rehydrated. Disc 1.2-1.5 mm diam., smooth, plane or undulating, margin even. Receptacle discoid, smooth, rather broadly attached, with a trace of whitish anchoring hyphae at the perimeter when dried. Asci 8-spored, 26.5-31.4 × 0.9-1.3 μm, narrowly cylindric-clavate, tapered and sometimes forked at the base, apex rounded or truncate-rounded, J– in Melzer’s reagent. Ascospores narrowly clavate, broadest above and slightly tapered to the rounded base, curved, smooth, hyaline, nonseptate, usually overlapping and biseriate within the ascus, 6.9-9.8 × 2.9-3.4 μm. Paraphyses hyaline, filiform, often branched below, <0.6 μm diam., abruptly expanded to 0.98-1.47 μm at the apex, which slightly overtops the asci that are somewhat encrusted but not immersed in a continuous epithecium. Ectal excipulum composed of angular or subangular isodiametric cells, 6.8-10.8 μm diam.

Note：
This species was originally reported by Wu (1998) as O. cf. auricolor because the original Fushan sample differs in several respects from typical material. The apotheicia of Taiwan sample are whitish yellow, but larger than usual, with asci slightly smaller than expected and ascospores a little shorter than O. auricolor reported from literature. Furthermore, the fern Angiopteris lygodiifolia as the substrate of O. cf. auricolor has never been reported elsewhere. However, after sending the further collecting samples to Hans Barral, he confirmed that Fushan sample and the other O. cf. auricolor samples should be the species of O. auricolor.
