 Description: Stromata up to 2 mm across, epiphyllous, scattered, elliptical, seated on the unaltered palisade tissue, at first covered by a black shinning epidermal clypeus, later rupturing and bursting through the epidermis, becoming rough and apparently superficial, composed of pseudoparenchymatous, black, polygonal cells, not forming any leaf spot, with long neck protruded. Ascostromata immersed, globose with a long neck, closely packed of 1 to 6 individuals in each stroma, sometimes laterally compressed, 120-355 μm wide, 442-514 μm high, including the neck. Neck cylindrical, 178-356 μm high, 118-158 μm wide, periphysate. Peridium 16-40 μm thick, composed of 5-10 layers of pseudoparenchymatous, black, oblong cells, the wall of neck plectomycetous, 20-30 μm thick. Asci paraphysate, cylindrical, unitunicate, 59-68 × 6-8 μm, 8-spored, periphery in the centrum, with non-amyloid apical ring. Ascospores brown, smooth, uniseriate arranged in the ascus, ovoid, unequally 1-septate in lower third, the lager 6-8 × 5-6 μm, occasionally with brighter band, the smaller cell 4-5 × 3-4 μm.

 Note: This species is very common on members of Leguminosae in many different genera (Müller and von Arx, 1962), but it only found on Bauhinia championi in Taiwan. The ascospores are found to have an equatorial band and germ pores in the Taiwan specimens. This slightly differing from the species reported by Müller and von Arx (1962).
