This is the first report of the occurrence of Cercospora sequoiae as a pathogen of Cryptomeria japonica in the United States. Koch's postulates were fulfilled on rooted cuttings indoors; the fungus caused dark brown lesions on succulent needles and stems. Conidiophores were fascicled and measured 40-107 μm. Conidia were brown, 33–80 μm × 4–6 μm, echinulate and 3–8 septate.
