The 2015 Powdery Mildew Survey is coming… Will yours be one of the 144 species previously recorded within the UK, on one of thousands of host plants previously recorded? Will it be one to have recently expanded its host range? A new species to the UK? Or a previously unrecorded species?!
Kew Fungarium houses around 1.25 million specimens!
To be launched officially at the turn of spring the survey aims to establish which of the ca. 800 powdery mildew species found worldwide are present within the UK.
The online resources provided by Kew Botanic Gardens and the International Powdery Mildew Project have allowed me to collate a list of powdery mildews recorded within the UK. From this, somewhat ancient, baseline I will be able to establish the status of powdery mildews collected and received through the scheme in the coming year.
Below you can see the breakdown of previously recorded species within the 14 genera, to a total of 150 species (of which 6 are synonyms). Follow the link for a full list of UK powdery mildews in Excel format.

| Erysiphe | 85 |

Oli, How many of these species were found during the 2013 and 2014 surveys?
Fay, 51 different species I believe, though some of these were collected by myself as well (so not just through the survey).
