First report of Fuligo gyrosa causing slime mold disease in chrysanthemum

Abstract

The fruiting bodies and plasmodia of slime molds were found on small-flowered chrysanthemums (Chrysanthemum morifolium Ramat.) in an open field in Nara Prefecture, Japan. The damage was limited to the bottom leaves with fruiting bodies. The isolate was identified as Fuligo gyrosa (Rostaf.) E. Jahn based on its morphological characteristics and BLAST analysis. This is the first report of F. gyrosa causing slime mold disease in chrysanthemums.
