These extraordinary growths are caused by a miscroscopic mite called Eriophyes tiliae, and it is commonly known as the Red Nail Gall Mite.
They appear on the upper surface of the leaves of Large-leaved Lime (Tilia platyphyllos) and the hybrid Common Lime(Tilia x europaea). I found this tree in a local park covered in them.

How bizarre, I have seen the gall on oak leaves and I suppose these have the same devastating effect?

This gall is species specific, but I suppose their are other similar galls out there. They don’t appear to harm the tree, thankfully.

Thank you, Steve. Galls are very interesting, and when you think there are just over 1,000 species here in Britain I have only really scratched the surface. I am on the look out for more 🙂 I have seen your gall before and commented, and it is a real beauty!
