Abstract ▼ AI-Helper

The powdery mildew found on Magnolia kobus was recorded as Microsphaera alni for the first time in Korea in 1975. After splitting M. alni into several distinct species, this mildew was regarded as Microsphaera magnifica, now Erysiphe magnifica. Since E. magnifica is known to be a North American species, the powdery mildew found on M. kobus in Korea was studied to clarify its identity. Based on morphological characteristics and sequencing results of the internal transcribed spacer and large subunit rDNA gene, the powdery mildew found on M. kobus in Korea was identified as Erysiphe magnoliicola.

D: Conidia. E: Conidia in germination. D and E comprise the same magnification. F: Numerous chasmothecia formed on the lower leaf surface. G: Close-up view of chasmothecia. H: Chasmothecium with 15 appendages. I: Chasmothecium with asci and ascospores. H and I are presented at the same magnification.
