 Note: It is similar to Dicephalospora rufocornea by the orange-red, stipitate apothecia, fusoid ascospores, and excipular structures, but the latter has larger and brighter colored apothecia, asci and ascospores. The ascospores of D. rufocornea have gelatinous collar at poles and the paraphyses are straight not curved at the tips. Zhuang (1995) mentioned the apothecial tissues does not exude pigment in 2% KOH solution, however, small amount of dark red pigment emitting from dry specimens in KOH solution was observed from Taiwan sample. Collections were found all year round at Fushan Botanical Garden, on dead leaf petioles of Fagaceae species.
