abstract = {Diaporthe species are common pathogens, endophytes, or saprobes on a wide range of hosts. During our investigation of forest pathogens, we made collections of Diaporthe species associated with canker and dieback disease of Betula platyphylla and B. albosinensis in Sichuan and Shaanxi provinces inChina. Diaporthe betulae sp. nov. and D. betulicola sp. nov. are introduced in this paper, with illustrations, descriptions and support from internal transcribed spacer (ITS), calmodulin (cal), histone H3 (his), translation elongation factor 1-α (tef1-α) and beta-tubulin (β-tub2) multigene phylogeny. Diaporthe betulae is characterized by hyaline, ellipsoidal, aseptate, biguttulate, 8.5?11 ? 3?4 ?m alpha conidia, with a known distribution in Sichuan Province, China. Diaporthe betulicola is characterized by pycnidial stromata with a single locule with one ostiole per disc. Alpha conidia are hyaline, oblong, aseptate, not biguttulate and 9.9?14.7 ? 1.3?2.5 ?m, and beta conidia are hyaline, spindle-shaped, curved, aseptate, 17?24 ? 0.7?1.2 ?m, and was found in Shaanxi Province, China.}
