Habit, habitat and leaf shape seem right. Also parasitised by Lamprospora tortulae-ruralis, which could be specific to S. calcicola over other S. ruralis complex members.
Smooth red tubers and leaves lacking distinct elongated border cells.
Hayhurstia atriplicis is actually an aphid. We infer that the pale leaf-roll found on several species of Atriplex, is caused by the aphid's attention to the under-surface of the leaf of Atriplex.
It is a sound assumption IF you can discard three other organisms, two diptera and one fungus - Picture 7. Their effects on the leaf are quite different, so it's a fairly easy call.
The pseudo-gall itself is very distinctive, pale, swollen, tightly inrolled (curled) and distorted. It is important to look for the Aphid, and photograph it for 'final' evidence.
