White spots with brown tips
On the lower surfaces of several mature tree branches - and on several tree types - I have found many small white spots (2-5mm dia) that look like insect "eggs". Some spots have brown tips on them.
The trees are in a small clump of relatively dense bushes and shrubs and do not get a lot of sun.
I am not an greatly experienced gardener and I know nothing of trees!
Should I be worried?
What can I do about them?
