Abstract
Leaf gall was occurred on Rhododendron indicum(L.) Sweet[=Azalea indica L.] in a farmer's garden located in Geumsan-myon, and along the walk way of Gangju pond in Jeongchon-myon, Jinju, Korea. The infected leaves was deformed into very conspicuous, pale, fleshy shapeless galls. Basidia were fusiform, $3{\sim}5$ sterigma, and $8{\sim}35{\times}3{\sim}6{\mu}m$ in size. Basidiospores were musiform, straight or curved and $10{\sim}22{\times}3{\sim}5{\mu}m$ in size. The causal organism was identified as Exobasidium japonicum Shirai based on the mycological characteristics of the fungus and pathogenicity. This is the first report on the leaf gall of R. indicum caused by E. japonicum in Korea.
