First report of Seimatosporium hypericinum causing leaf spots on the ornamental shrub Hypericum ?? inodorum and in Brazil

摘要

Hypericum ??inodorum is an ornamental plant that has become popular for the cut flower industry in Brazil, in recent years. No pathogen has been reported on this plant in Brazil. A coelomycete asexual morph was found associated with leaf spot and severe foliage blight on this host and is reported here for the first time. A combination of morphological and molecular features allowed it to be identified as Seimatosporium hypericinum. Kocha??s postulates were performed and demonstrated, for the first time, that S. hypericinum is pathogenic to H. ?? inodorum.
