摘要： Two specimens of Xylaria were collected from Jilin, northeastern China, during a field trip in August 2014. They are described and illustrated here as new species, i.e. Xylaria crinalis and X. betulicola, based on a combination of morphological and ITS sequence data.They share thread-like stromata with a long sterile filiform apex. Xylaria crinalis is similar to X. betulicola from China in both macro- and micro-morphological features, except its few scattered perithecia, more or less conspicuous germ slit, slightly larger and narrower ascospores, and occurrence on wood. In the phylogenetic analysis the two Chinese species clustered with X. filiformis from Iran into a subclade within the genus Xylaria Glade, but were separated from other species as well as from each other.
