Fungi of the genus Geosmithia are frequently associated with bark beetles that feed on phloem on various woody hosts. Most studies on Geosmithia were carried out in North and South America and Europe, with only two species were reported from Taiwan, China. The aim of this study was to investigate the diversity of Geosmithia species in southern China. Field surveys in Guangdong, Guangxi, Hunan, Jiangxi and Shanghai yielded a total of 76 fungal isolates from six beetle species. Isolates were

Phylogenetic trees were constructed based on those sequences. In total five species were identified, with one previously described species G. putterillii and four new species which were described as G. jiulianshanensis, G. jiangxiensis, G. formosana, and G. pulverea (Geosmithia sp. 3 and Geosmithia sp. 23) sp. nov., in this paper.
