DC6220FAD697D915F225F86429360B21.taxon	description	Description. Sexual morph: Pseudostromata small to large, distinct, circular, erumpent, consisting of an inconspicuous ectostromatic disc, semi-immersed to superficial, causing a pustulate bark surface. Ectostromatic disc flat or concave, orange, surrounded by bark flaps. Central column beneath the disc more or less conical. Stromatic zones lacking. Ascomata perithecial, conspicuous, umber to fuscous black, embedded in orange to umber pseudostromatic tissue, regularly scattered, surrounding the ectostromatic disc, with small to long ostioles that emerge within the ectostromatic disc. Ostioles flat in the disc or sometimes slightly projecting, cylindrical, sometimes obscuring the disc, covered by an orange, umber to fuscous black crust. Paraphyses deliquescent. Asci fusoid, 8 - spored, 2 - 3 - seriate, with an apical ring, becoming detached from the perithecial wall. Ascospores hyaline, fusoid to cylindrical, symmetrical to asymmetrical, straight to curved, bicellular, with a median septum, constricted at the septum, smooth, multiguttulate. Asexual morph: Conidiomata pycnidial, spherical to conical to pulvinate, occurring separately, immersed to semi-immersed in bark; wall of several layers of yellow textura angularis. Central column beneath the disc conical or not. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner walls of cavity, hyaline, smooth, subcylindrical to ampulliform. Conidia hyaline, aseptate, smooth, multiguttulate or not, thin-walled, ellipsoid to fusoid, straight to curved.	en	Jiang, Ning, Fan, Xin-Lei, Crous, Pedro W., Tian, Cheng-Ming (2019): Species of Dendrostoma (Erythrogloeaceae, Diaporthales) associated with chestnut and oak canker diseases in China.
