【 摘 要 】

Downy mildew disease was observed for the first time from Lipochaeta integrifolia, a G3-vulnerable plant native to Hawai‘i. The oomycete infecting the plants was identified as Plasmopara sphagneticolae by morphological and molecular means. This marks the first report of P. sphagneticolae outside of Australia on a new host. This disease may have significant implications for conservation efforts of L. integrifolia and other endangered native Asteraceae on the islands.
