Plants in the Alpine House or Cold Frame: Benign mould

I have fine four-year-old cushion of Draba mollissima in the alpine house. This summer it has exuded a frothy liquid on several occasions. It appears to have done the plant no harm except to discolour some rosettes. I thought at first the cause was a slug or a snail but discounted this theory after setting traps. A senior member of the Society suggested it could be a benign mould because he had observed something similar in the garden. Is this one for Hercule Poirot or does anyone out there have a better explanation?
Are you sure it isn't a froghopper?
