platystoma
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 platystomais 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, Sichuanand YunnanProvinces 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.
