Abstract: Therrya guizhouensis (Y. R. Lin & B. F. Hu) Lan Zhuo & C. L. Hou comb. nov. Coccomyces guizhouensis Y. R. Lin & B. F. Hu, in Lin, Liu, Tang & Hu, Acta Mycol. Sin. 13 (1): 8. 1994. Basionym. Type. CHINA, Guizhou Province, Zhijin, alt. ca. 1700 m, on twigs of Pinus armandii Franch. (Pinaceae), 2 May 1979, B. F. Hu 16393 (ACAFP 66501, holotype). Notes. Lin et al. (1994) described Coccomyces guizhouensis on twigs of Pinus armandii in the genus Coccomyces. In our phylogenetic tree, sequences of C. guizhouensis form a sister clade to Therrya pinicola (synonym Parvacoccum pini) and Therrya strobi (synonym Coccomyces strobi). Therrya pinicola differs from C. guizhouensis by having a dark zone below the subhymenium and ascospores with more obtuse ends. Coccomyces strobi differs from C. guizhouensis by having asci with slightly pointed apices and ascospores that are filiform-clavate with rounded apex. Although the ascospores of Co. guizhouensis are not septate, they are fusiform in shape and the apex of paraphyses are sometimes enlarged and form an epithecium. Based on the phylogenetic position and morphological characters, C. guizhouensis is transferred to the genus Therrya here.
