it would appear that my source for that name also lists it (and similar spp.) as occurring in Great Britain. BugGuide indeed. Thanks, Byrain.

Not all anthropod galls are Insecta, but given its appearance and that its on an Oak, it might be safe to call it Cynipidae. Does N. numismalis even occur in the US? What little information I have found indicates its found in the UK.

Dave, please post these on bugguide, thanks!

Thanks, Danny.

At least I can be certain it’s not fungal.

does not look fungal

if it’s a gall, I suspect it’s an oak spangle gall (Neuroterus spp.), possibly N. numismalis. it is very deteriorated.

But post what you see and we should be able to sort it out from there. Obviously, asci, basidia or clamps are a good sign it’s fungal.

Danny, what microscopic features may be of interest?
