Another unknown ID from my image clear out.
This is one, of quite a few I found on the underside of ivy leaves in May 2007. They were flat, smooth and dry to the touch and this particular specimen measures 11mm. You can see in the photo that something appears to be hatching from it. The more I look at it, I think these are the last few to hatch, lots of the bubble looking parts seem to have openings already.
Any ideas please?
