Ciliochorella castaneae previously reported only from the leaves of Castanea europaea and Tilia sp. in India is described and illustrated as the first record of the species from northern Japan. It was collected on leaves of angiosperms, such as Fraxinus lanuginosa, Viburnum dilatatum, Cercidiphyllum japonicum, Kalopanax pictus, Fagus crenata and Betula ermanii, as well as on a fern, Pteridium aquilinum. Phylogenetic analyses based on the 28S nrDNA suggested that C. castaneae belongs to Amphisphaeriaceae, Xylariales and is close to an anamorphic group, 'pestalotioid fungi' such as Seiridium and Monochaetia.
