Plasmopara sphagneticolae sp. nov. (Peronosporales) on Sphagneticola (Asteraceae) in Australia

Australasian Plant Pathology, 2014
A specimen of downy mildew on leaves of Sphagneticola trilobata found in northern Queensland was identified by a systematic approach as a novel species of Plasmopara. A new species, Plasmopara sphagneticolae, is proposed for this specimen, which differs from other species of Plasmopara by morphology, host range, and sequence data from nuclear-ribosomal

Revision of Plasmopara (Oomycota, Peronosporales) parasitic to Impatiens

Mycological Progress, 2017
The oomycete Plasmopara obducens was first described on wild Impatiens noli-tangere in Germany in 1877. About 125 years later the first occurrence of P. obducens on cultivated I. walleriana in the United Kingdom was reported, and a worldwide epidemic followed.

Genome Size Determination in Peronosporales (Oomycota) by Feulgen Image Analysis

Fungal Genetics and Biology, 1998
Genome size was determined, by nuclear Feulgen staining and image analysis, in 46 accessions of 31 species of Peronosporales (Oomycota), including important plant pathogens such as Bremia lactucae, Plasmopara viticola, Pseudoperonospora cubensis, and Pseudoperonospora humuli. The 1C DNA contents ranged from 0.046 (45. 6 Mb) to 0.163 pg (159.9 Mb). This
