17 sep some foam
19 sep foam
Description:

At first I thought it was chewing gum, but the texture was different, sort of sticky. It was tigtly stuck to the straw, and I wouldn't spoil it, if it was/ is a shelter for some carterpillar or an insect. 2. picture is a similar structure in the same rather moist grassland indicating that it is not an unusual occurrence.

silk?

From your photos and description this seems to be too solid to be the foam produced by nymphs of cuckoo-spit bugs (Aphrophoridae). Mydaea may well be correct that it is a slime-mould, but if the structure was made of silk then a moth cocoon might be a possibility, or maybe a spider's egg sac. However, as far as I can tell from the photos there doesn't seem to be any trace of silk threads in the structure.
