This observation is for the unusual growth and NOT for the plant.
Host: Symphyotrichum ericoides
Possibly the same gall former as featured here:

Also have previously found suspected Rhopalomyia gemmaria at this prairie remnant:

Very hard to cut it open
Host plant: Sandpaper oak (Quercus vaseyana)
Blackjack Oak. Collected 1 for cross section, but I did that last year. Probably too early to rear.
One of three males observed near the porch light this morning.
SRK1141
Wise County, Texas.
Collected with Bob O'Kennon, Tiana Rehman, and Kim Taylor.
While I was collecting Polystepha galls to rear out, I noticed quite a few galls that were much smaller, not as crackly textured, and seemed to be different than the Polystepha globosa they appeared with. Even the larvae were different colored. Separated them out into a different rearing container on the off chance I can get adults to compare with P. globosa.
I collected and measured 16. Average size 1.7mm compared to P. globosa which is 2.6mm.
Not great photos
Inducer emerged from Andricus ignotus galls collected here: https://www.inaturalist.org/observations/65443224. Preserved in vial 82a.
I suspect virus, but really have no clue. Blackjack Oak
Soooo many Triodanis observations. They are prizes for @Kimberlietx, who challenged me to find like 100 species. LOL. City Nature Challenge Day 2: Dallas - Fort Worth (DFW). Observing at a residential retention pond with a wooded trail that is adjacent to the Hickory Creek Arm of Lewisville Lake in Denton County, Texas.
On Quercus stellata
I thought this might be the same gall as https://www.inaturalist.org/observations/74765398 but it has multiple emergence holes, which isn't an Andricus sp thing. Collected.
Found R pascuus and pensilvanicus growing side by side. The R pascuus is not yet in bloom, but the R pensilvanicus is fully in bloom.
On Quercus stellata. Based on previous feedback most likely A. murtfeldtae or maxwelli
@calconey @megachile @kimberlietx @jeffdc, collected some of these same galls from a tree near the previous observation (https://www.inaturalist.org/observations/74158192). Have the stem in my posession and left some galls on the tree. I can add any perspectives or try any methods (dissection, letting them hatch to see what comes out, etc., if you can walk me through the necessary steps to do so) that would help in identifying these galls to species level. Many thanks for the help and enthusiasm in identifying these so far.
Several dozen examples of, Rosa foliolosa, not previously observed in this area of thick grasses. Most specimens had the galls.
Clasping Venus's Looking Glass (Triodanis perfoliata)

Shumard Oak
The wool comes off in an average manner. (Not too easily, but not too difficult either.) The galls seemed to be tiny kernels (Pic 7) stuck together with long irregular length wool that "doesn't have visible segments at all; the longer, straighter wool from each kernel just blends together" to quote @megachile They were firmly involved in the midvein and not easy to remove. They were slightly smaller than a sesame seed.
Current northern-most known population of this species, as of the day I posted this (11 August 2019).
Galls on leaves of a tree in the white oak group (possibly Quercus austrina x stellata).
swept from Ceanothus, but presumably originated from perhaps goldenrod which grows nearby
I had to key this one out. The really wide pores made me think it might be T. lamprosperma, but the bracts are longer than wide and the leaves are broadly acute to obtuse, which are both key characters of T. perfoliata.
Appears to be growing on the back of an oak leaf
Despite the more oval, elongate shape, the best thing I can match these galls to is the genus Dryocosmus. Other suggestions are welcome.
I am basing this on the cross-sectioned seed (last photo) which is quadrangular (vs lenticular). Stems and leaf underside are pilose mainly along the veins, not hirsute which would be consistent with T. perfoliata var perfoliata. So if I am wrong, that is my second choice.
Spots don't line up for Kyoto Moth. Wing tips are pretty fringe-y looking and not very spotted.
