Caryomyia conoidea
Gagne Description 3
Occasional, on Eucarya hickories; single or in groups, on lower leaf surface between veins; height 3.8-5.0 mm, generally conical, edge at base rounded, base adjacent to leaf uniformly hard, conical and often with cylindrical extension at apex, sides developing longitudinal ridges and furrows upon maturity; green to red or brown surface smooth, with sparse, short, erect, white to tan hairs not obscuring surface; base with central, circular, shallow depression, leaf with short, irregular exfoliation surrounding basal connection to gall; larval chamber basal, depressed-ovoid, lined with yellowish membrane, contrasting with brown to purple, large-celled, spongy, viscous tissue surrounding larval chamber that shrivels with age and traversed by bundle of fibers between larval chamber and gall apex. This gall is most similar to that of C. sanguinolenta, q.v. for remarks.
