Yes, Elaine, and thank you, that's just what happened I feel sure.
The spots are not raised bumps; they are flat. I see similar white spots now that I am looking for them on a small dahlia in a different bed, and also on some calamint I planted way down the yard. Though much less on the calamint. This soil is in very bad shape in most places and the watering has not fully made up for lack of rain.
I'll try to get more pictures tomorrow or next day. (Things are busy right now!)
thanks again, all!
