Botryosphaeria rosaceae sp. nov. and B. ramosa, new botryosphaeriaceous taxa from China

[摘要] A new species of Botryosphaeria (B. rosaceae) is described and illustrated from Rosaceae in China. Phylogenetic analysis based on combined ITS, LSU, tef1-α and TUB loci supported its separation from another species of Botryosphaeria. Morphologically, B. rosaceae was comparable with B. sinensia, but the smaller and slenderer ascospores and conidia as well as the broader host spectrum of B. sinensia differentiate it from B. rosaceae. In addition, Botryosphaeria ramosa was found associated with an Acacia species in this study, which is a new host and first report in the Northern Hemisphere.
