Tian, Z. Du & K.D. Hyde. Mycosphere 8(2): 1249 (2017). Fig. 5 Description. Saprobic on decaying branches of Zanthoxylum bungeanum . Sexual morph : Not observed. Asexual morph : Coelomycetous, Conidiomata 558-657 x 216-241 μm ( x̄ = 235.5 x 228.5 μm , n = 10), immersed, partially erumpent when mature, multilocular, locules separated by pale brown cells of textura angularis . Peridium 65-106 μm wide, wall 6-10 cell-layers thick, outer layers composed of 3-4 layers of pale brown cells of textura globulosa , intermediate layers composed of dark brown cells of textura angularis , becoming pale brown towards the inner region. Ostiole 138-171 μm diam., central. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 12-13 x 7.5-8 μm ( x̄ = 12.5 x 8 μm , n = 20), holoblastic, hyaline, cylindrical to doliiform, smooth-walled. Conidia 17-20 x 6.5-7.5 μm ( x̄ = 18.5 x 7 μm , n = 30), L/W ratio = 2.5, ellipsoidal to subcylindrical, with both ends rounded, initially hyaline, becoming dark brown, aseptate. Figure 5.

Material examined. China , Sichuan Province , Yaan City , Hanyuan County , 29°16'51"N , 102°37'48"E , elevation 1,689 m , on dead branches of Zanthoxylum bungeanum , 30th October 2021 , W.L. Li , HJ 511 (HUEST 22.0092), living culture UESTCC 22.0091 . Notes. Aplosporella ginkgonis was introduced by Du et al. (2017) and isolated from diseased branches of Ginkgo biloba and Morus alba from Gansu Province in China. One isolate (UESTCC 22.0091) obtained in this study from Zanthoxylum bungeanum is morphologically similar to the original description of Aplosporella ginkgonis , and the sequences data are identical to the previous data (99%-100%). We, thus, identify the new collection as Aplosporella ginkgonis and this is the first report from Zanthoxylum bungeanum .
