Re-collection of Dermea prunus in China, with a description of D. chinensis sp. nov.
Ning Jiang | Cheng-Ming Tian
Dermea was protected against its synonym, Foveostroma, due to its well-circumscribed generic concept and more frequent use. We describe and illustrate Dermea chinensis sp. nov. based on its morphological characteristics and a molecular analysis of the internal transcribed spacer (ITS) and large subunit (LSU) sequence data. Dermea chinensis is isolated from Betula albosinensis with sexual and asexual morphs and can be distinguished from D. molliuscula on Betula trees by its aseptate and wider ascospores. The connection between the two morphs is proved based on sequence data. Here, we describe the asexual morph of D. pruni for the first time based on morphological and molecular data from the same host and country of origin, and compare it with other species of Prunus.
