Well, if you're planning on doing the trees surrounding Dol Guldur (as in your pictures), they don't really have foliage on them. I would suggest (as you said) adding spider webs, and also add some vines (poison ivy vine type), and paint the trees a greyish colour to make them look dead and haunted, but also add some hints of green in it (I'd suggest a green wash in various areas of the trees, but not too much) to give a sickly effect.
If you do want to add leaves however, very dark green lichen gives a very good effect for Mirkwood. You could even try and get some dry tea leaves from a teabag and mix that in with the lichen, which also gives a very nice effect.
I hope that helps!
It certainly does!
Tea leaves sound like a great idea, I'll do a few tests with different materials and perhaps post the results.
