Taxonomy of two synnematal fungal species from , with gen. nov. described.

represents a commercially and ecologically important tree species in China, but suffers from canker diseases in Jiangxi Province. Synnemata, pycnidia and ascomata were discovered on cankered tissues. Strains were obtained from single ascospore or conidium within the fruiting bodies and identified based on morphological comparison and the phylogenetic analyses of partial ITS, LSU, and gene sequences. As a result, two species were confirmed to represent two kinds of synnemata. One of these species is described herein as ; and is illustrated showing ascomata, pycnidia and synnemata. is distinguished from by the colour of the synnematal tips. Additionally, can be distinguished from the other gnomoniaceous genera by the formation of synnemata.
