| Abstract: | A hyphomycete consistently isolated from dead oak trees (Quercus serrata and Q. mongolica var. grosseserrata) attacked by the ambrosia beetle Platypus quercivorus in Japan is described and illustrated as Raffaelea quercivora sp. nov. The new species is characterized by having small obovoid to pyriform sympodioconidia and slender, long conidiophores
that taper to a point. The fungus has been isolated from the body surfaces and mycangia of the beetle. It is likely that the
fungus was transferred to oak trees by P. quercivorus.
