Chen & Jian K. Liu. Phytotaxa 508 (2): 190. (2021). Fig. 16 Description. Saprobic on decaying branches of Pistacia chinensis . Sexual morph : Not observed. Asexual morph: Conidiomata 223-232 x 150-176 μm ( x̄ = 227.5 x 163 μm , n = 10), dark brown to black, globose, submerged in the substrate, partially erumpent at maturity, ostiolate. Ostiole 28.5-45 μm diam., circular, central. Peridium 21-30 μm thick, composed of dark brown thick-walled cells of textura angularis , becoming thin-walled and hyaline towards the inner region. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 6-9.5 x 3.5-5 μm ( x̄ = 7.5 x 4 μm , n = 20), hyaline, short obpyriform to subcylindrical, holoblastic, indeterminate. Conidia 20.5-24 x 11.5-14 μm ( x̄ = 22 x 13 μm , n = 30), L/W ratio = 1.6, ellipsoid to ovoid with both ends rounded, hyaline, aseptate, externally smooth, internally finely verruculose. Figure 16.

Scale bars: 40 μm ( d ); 20 μm ( e, f ); 10 μm ( g-n ). Culture characteristics. Conidia germinate on PDA within 12 h. Colonies growing on PDA, reaching a diameter of 7 cm after five days at 25 °C, effuse, velvety, with entire to slightly undulate edge. Surface initially white and later turning dark olivaceous from the surrounding of the colony and dark gray in reverse. Material examined. China , Sichuan Province , Chengdu City , Pidu District , 29°16'50.70"N , 102°37'47.53"E , elevation 442 m , on dead branches of Pistacia chinensis , 19th March 2021 , W.L Li , 047 (HUEST 22.0101), living culture UESTCC 22.0100 ; ibid ., 070 (HUEST 22.0102), living culture UESTCC 22.0101 ; ibid ., 071 (HUEST 22.0100), living culture UESTCC 22.0099 ; ibid ., 150 (HUEST 22.0098), living culture UESTCC 22.0097 ; ibid ., 151 (HUEST 22.0099), living culture UESTCC 22.0098 ; ibid ., A39 (HUEST 22.0103), living culture UESTCC 22.0102 ; ibid ., A40 (HUEST 22.0104), living culture UESTCC 22.0103. Additional sequences: LSU: OQ164842 (UESTCC 22.0100), OQ164843 (UESTCC 22.0101), OQ164844 (UESTCC 22.0099), OQ164845 (UESTCC 22.0097), OQ164846 (UESTCC 22.0098), OQ164847 (UESTCC 22.0102) . Notes. Seven isolates of our collection are morphologically similar to the original description of Sardiniella guizhouensis ( Chen et al. 2021 ). The multi-gene phylogenetic analysis showed that the newly obtained isolates clustered together with ex-type of Sa. guizhouensis (CGMCC 3.19222) and this is the first report of Sa. guizhouensis from Pistacia chinensis .
