Galls

More on today’s activities around Meadale, south of Struan on Skye later, but for now Gall News:

Eriophyes inangulis

These galls are on Alnus glutinosa (Alder) and are caused by the gall mite Eriophyes inangulis. They grow in the angles between the midrib of the leaf and the side veins.

Also on alder was Taphrina alni (Alder Tongue) which grows on female cones:

Alder Tongue

On Urtica dioica (Common Nettle) I found a different gall from my usual rust Puccinia urticata, this one caused by a small Cecid fly, Dasineura urtica:

Nettle Leaf Gall

I also spotted a gall on Galium aparine (Goosegrass/Cleavers/Sticky Willie etc) caused by the mite Cecidophyes galii, but have no photo of it.
