gall

Galls like these are commonly associated in the cecidological literature with Stenacis triradiata, albeit not without some hesitation, because generally several more gall mite species co-occur in the gall. Presently one supposes that a mycoplasma, rather than eriophids, is the primary causer (Pye, 2012a).
