"Aggregate bud galls that resemble those of A. monacha on S. juncea and S. erecta are known from several other goldenrod species, including S. patula, S. odora, and an undetermined Solidago species from Florida, based on material in the National Museum of Natural History, Washington, D.C. (USNM)."

[GF note: Since this publication, Solidago chapmanii, formerly a variety of Solidago odora, has been elevated to species. It's not clear whether the record above refers to S. odora in the strict sense, or instead to S. chapmanii. Asphondylia solidaginis-like singly-occurring bud galls have been observed on iNaturalist on both S. chapmanii and S. odora; there is a separate gallformers page for those galls here and here.]
