Abstract

Due to the strong morphological similarity of the powdery mildew fungi that infect papaveraceous hosts, a total of 38 samples were studied to reveal the phylogeny and host range of these fungi. ITS and 28S sequence analyses revealed that the isolates identified earlier as Erysiphe cruciferarum on papaveraceous hosts represent distinct lineages and differ from that of E. cruciferarum sensu stricto on brassicaceuous hosts. The taxonomic status of the anamorph infecting Eschscholzia californica was revised, and therefore a new species name, Erysiphe eschscholziae is proposed. The taxonomic position of the Pseudoidium anamorphs infecting Glaucium flavum, Papaver dubium, Meconopsis cambrica and Stylophorum diphyllum remain unclear. This study revealed that Erysiphe macleayae exhibits a specific host range different from that of E. cruciferarum, the common pathogen of papaveraceous hosts. Although E. macleayae occurred naturally on Macleaya cordata, Macleaya microcarpa, M. cambrica and Chelidonium majus only, our inoculation tests revealed that the fungus was capable of infecting Argemone grandiflora, Glaucium corniculatum, Papaver rhoeas and Papaver somniferum indicating that these plant species may also be taken into account as potential hosts. The emergence of E. macleayae on M. microcarpa is reported here for the first time from the Czech Republic and Slovakia. Erysiphe cruciferarum was observed to occur naturally on Papaver croceum, Papaver nudicaule and P. somniferum. In addition, this fungus was identified on G. corniculatum and reported here for the first time from Slovakia. The appearance of chasmothecia of E. macleayae on C. majus in Slovakia was reported, as well.
