thanks for the reminder of a cross-section – my colleague was confident it was slime so I did not think of it. It would have easily resolved the issue.

This could be some kind of insect gall, there are many on oak leaves, I don’t know eastern galls at all though. Maybe you can try bugguide.net? A cross section could also help tell if its a gall for those of less experienced and if its an gall, knowing what kind of oak would help.
