Stromata usually widely effused, brownish but seemingly black because of closely studded with black and discoid ostiloles, surrounded by a black line within the substrate; perithecia monostichous or distichous, singly erumpent, 150– 200 µm diam., with short ostiolar necks. Asci cylindrical, paraphysate, 20–25 × 4–6 µm in spore bearing part, stalks of different length, containing 8 biseriate ascospores, apical ring indistinguishable. Ascospores one-celled, almost straight and hyaline, very thin, 7–9 × 1–1.3 µm long. Diatrype platystoma is now commonly referred to as Graphostroma platystoma (Schwein.) Piroz. , although it hardly deserves its own genus. We have already discussed the unfortunate travel of this species through different taxa ( Vasilyeva & Stephenson 2004 ). It is widely distributed in eastern and south-eastern provinces of China ( Anhui , Guangdong , Guangxi , Hebei , Hunan , Zhejiang ); Shaanxi , Sichuan and Yunnan Provinces are the western limit of the area known. The general area of distribution is temperate forests of the north-eastern Asia and eastern North America (‘Asa-Gray disjunction’), but, unlike many other members of Diatrype , this species does not display any preference to host plants. In the north-eastern Asia, it is most commonly found on Acer , Betula , Crataegus , Corylus , and Malus .
