[fairplay]

There have been many previous threads on this subject and evidently not all these strange jelly like masses/blobs are the same thing.

There seems to be a tendency to call ANY clear or greenish or whitish jelly-like substance Nostoc commune (a cyonobacteria) but there are other species of Nostoc and there are many other clear jelly blobs suggested as being Red Deer Stag semen, a substance excreted by frogs or toads, algae, and many more suggestions.

Even a decent photograph would probably be insufficient to narrow down the source.

PS. The Welsh have even given any substance like this the name Powdre See (sorry if that is the wrong spelling) but nobody knows WHICH substance the inventor was actually referring too.
