Powdery mildew of campfire crassula (Crassula capitella subsp. thyrsifolia) occurred in Ibaraki prefecture in March 2014. We analyzed pathogenic-ity, morphological characteristics and rDNA-ITS region of the causal agent of the disease, and iden-tified the causal agent as Pseudoidium sp. We for-mally named the disease 'powdery mildew of camp-fire crassula' as a new disease of the plant in Japan.
