sus_scrofaDescription
this appears to be an integral stem gall on the stem of a western bunchberry (Cornus unalaschkensis). I didn't notice it in the field at all, only on subsequent review.
gallformers has no data on western bunchberry. the closest thing I found might be Resseliella clavula, an integral stem gall on Cornus florida that seems range-limited to east of the Rockies, so it's probably not that? but if not, what is it? I wish I had noticed this in the field lol

Growth on twig of Pignut Hickory/Carya glabra.
Is this just an unformed fruit? Five parts, lack of petiole/stem, and time of year suggest not.
Nothing similar on Gallformers.

Andricus prescottiObserver
joshuacdeDescription
I didn't originally submit this observation because the pics aren't very good quality, but since this gall has such few uploads on iNat I decided to add it. On Quercus gambelli acorn cup. Glabrous and appeared pale whitish in the field; cylindrical shape with a flattened apex and apical "nipple". The area where it was protruding was raised above the rest of the acorn cup and the scales surrounding the base of the gall were significantly broader than normal, un-deformed scales. This definitely looks like a different species than the other Q. gambelli acorn cup gall I found at this location: https://www.inaturalist.org/observations/177569788

Q. rubra
Finally found some fresh ones! Galls were fully buried in a loosely-packed ant mound surrounding the base of a seedling - perhaps an example of the "ant sheds" Weld described? Honeydew and LOTS of ant activity.
Larva dissected out 8/5, preserved in 95% etOH.
