Gall on Meadowsweet

Thought it was a rust at first, but no spores (and nothing like it in DH Henderson)

Hi Adam,

It looks like the work of the gall midge Dasineura ulmaria.

Regards,
Mike.

Hello Adam,
I'd agree with Mike's identification - there are other species of Dasineura which use Filipendula but the galls are all fairly distinctive.

If you are interested in plant galls, whatever the causative agent, I'd recommend:
British Plant Galls by Redfern & Shirley, 2011 2nd edition, AIDGAP guide available from the Field Studies Council.

Thanks, both. I hesitated as the colour is a lot whiter than photos I'd seen. I guess it's just a case of age/weather/Pembrokeshire Clean Air 8-)
The sunglasses is a bit of a joke, we've had an appalling summer from a sunbathing point of view, but good for most fungi. Most days in July maxing at about 16C.
