Pseudoidium kalanchoes , retrieved from powdery mildew on Kalanchoe spp. in Asia, has been re-examined and reassessed based on phylogenetic analyses of the ITS and 28S rDNA regions. The results confirmed that sequences retrieved from Asian Kalanchoe powdery mildew have 100% congruence with sequences obtained from Erysiphe sedi on Sedum spp. A German collection of P. kalanchoes on Kalanchoe blossfeldiana was morphologically and genetically examined and analyzed and is designated as neotype with an ex-neotype reference sequence. Morphologically, the asexual morph on Kalanchoe spp. agrees with the asexual morph of E. sedi . Consequently, P. kalanchoes is reduced to synonymy with E. sedi .
