Overwintering adults of sycamore lace bug (Corythucha ciliata) infected by an unidentified pathogenic fungus were found on the stems of street trees of sycamore in Cheongju city. The objective of this study was to describe this entomopathogenic fungus infecting overwintering sycamore lace bug adults. This unidentified fungus colonized the insect adult body and formed white colony with subglobose clusters of conidiocarps. The size of conidiocarps was 300 to 400 ㎛ and each conidium was 15 to 20 ㎛. The conidiospore was globus and 2.5 to 3.0 ㎛ in diameter, and the hyphae were 1 to 5 ㎛ thick.
