Abstract

A typical rust symptom showing yellowish spots on upper surface and pustules on lower surface of leaves was observed on Japanese prickly-ash tree (Zanthoxylum ailanthoides) in Hyeonpo-ri, Buk-myeon, Ulleungdo, Korea in 2010. Based on the morphological characteristic of urediospores and tel-iospores, the rust fungus was identified as Coleosporium phellodendri. The urediospores were yellowish in color, globose in shape with annulated verrucae surface and 26∼37 × 22∼28 μm in size. The teliospores were reddish yellow, ellipsoid and 43∼63 × 23∼33 μm in size. Phylogenetic analysis of the 28S rDNA region sequences of this fungus supported that it belong to Coleosporium spp.. This is first record of C. phellodendri causing rust disease on Japanese prickly-ash tree in Korea.
