| Abstract |
|
Coleosporium neocacaliae, a needle rust fungus, was described and illustrated for the first time on the needles of Pinus koraiensis (Korean pine) in Korea. Detailed descriptions of the species were verified based on symptoms and signs, and light and scanning electron microscopic observations on aecia, aeciospores and peridial cells. The present needle rust fungus was apparently different from C. eupatorii, a solely recorded Coleosporium species on P. Koraiensis in Korea until this time, in having comparatively large sized aeciospores as 20-39 ×14-27 μm than those of latter species (size of aeciospores 15-27×10-20 μm). Verrucose surface structure of aeciospores in light microscopy was revealed to be annulated with three to four rings and root-like base in scanning electron microscopy. Aecial stage of C. neocacaliae were formed on the middle days of April to the early days of June and collected around the central parts of Korean peninsula, including high mountains of about 1,000 m above sea level. |
