Moved from Galls.

Well, it seems pretty clear that this is going to grow up to look something like this:

The poplar aphid gall in Felt's gall book that most closely resembles yours is Pemphigus rileyi (which may now be Eriosoma rileyi)--"Globose, red and yellowish, clustered leaf galls, usually near the base and on underside, diameter 1/5 inch, on quaking aspen." Not a perfect match for several reasons. I wish I'd checked Ron Russo's book when I had it. If it's not in there, this may well be an undescribed species.

Thanks for that
interesting info.
