Gallformers description of Unknown b-sarothroides-ball-gall sounds like it could be this one. Host Baccharis sarothroides. Last photo of an old gall on the same host plant.

trevorzookDescripción
What's going on here? Potential hybrid of S. laciniatum and S. perfoliatum, or just strange S. perfoliatum? Very deeply cleft leaves that are not connate. Lower cauline leaves only slightly clasping with long petioles. The stems are square at the base and round more than 18" above the ground, and pubescent where square only. The one stem with lower leaves alternate instead of opposite has a round stem throughout. The underside of the midvein is pubescent. The second to last picture is me holding a flower of nearby S. perfoliatum (left) and S. laciniatum (right) against this plant's flower (top), showing the larger size.

S. laciniatum and S. perfoliatum hybrid or just weird S. perfoliatum? Further notes in @trevorzook 's description.
Last photo with three flowers in the hand compare nearby S. perfoliatum (bottom right) with S. laciniatum (top right) and the plant in question (left)

Alternate leaves; basal leaves rounded/cuneate- not cordate; ray flowers showing 11 on photo but likely one missing; other similar Silphiums have opposite or whorled leaves. S. Radula is west of the Mississippi River

This gall had the whole flower drooping to the ground and weighed about as much as a walnut. The mosquitoes were terrible so I didn’t linger and hope to return for another look soon.

Extensive population consisting of thousands of stems across multiple acres. Plants do not have well developed cauline leaves. However, many basal leaves do not have an pinnatifid structure.

Galls I saw in early June this year, on Lindley’s Silverpuffs, all dried out. I couldn’t get out here until now @louisnastasi, but I collected a few.

Both compass plant and prairie dock grow nearby so maybe a hybrid between the two?

Several galls seen in this patch of fading Lindley’s Silverpuffs; there could be more. There are definitely more Silverpuffs. I lumped them in one observation.

On Lindley’s Silverpuffs, Microseris Lindleyi or Uropappus lindleyi. Serpentine prairie next to Barkley Field. Definitely not on Microseris douglasii. Lindley’s Silverpuffs seem to be formerly classified as genus Microseris, thought it was interesting.
Last year at Kite Hill Woodside I watched a couple folks on their hands and knees looking for these galls on the tiny Microseris douglasii.
