slime-mould, perhaps

Observation - slime-mould, perhaps - UK and Ireland. Description: I thought this might be something like the Dog Sick Slime Mould, Mucilago crustacea, or the Tapioca

I thought this might be something like the Dog Sick Slime Mould, Mucilago crustacea, or the Tapioca Slime Mould, Brefeldia maxima, but I really don't know, having no previous experience of slime moulds. As you can see from the photos, much of it was on damp leaf-litter (apparently growing round the edges), yet some was creeping up living grass.
