Q.Strange Looking Small “blobs” On Trunk Of Norway Spruce

Zone Hilliard, Ohio 43026 | Anonymous added on September 11, 2023 | Answered

Healthy, 50+ YO tree. Has white stuff all along trunk, but my concern is that I just noticed these small, yellow-ish small blobs (about the size of a nickel) coming out of some holes in the trunk. Maybe a dozen have been noticed. Many sap-sucker and woodpecker holes in trunk. I gingerly poked one, and it seemed membranous. Pic attached.

I spent a lot of time researching this and I'm not finding anything that looks quite like this. You may have insect holes in addition to woodpecker holes. I do think I see some clear resin leaking from the tree, which is gummosis that can be triggered by insects such as borers. It seems it must be insect related or a fungus. I suggest calling your local extension agent, who may have seen this before in the area. Here is how to locate him/her.
