Unidentified slime mould/fugus/alga?

unidentified fungus, slime mould, alga

HELP WANTED! UNIDENTIFIED! This was about a foot across and of gelatinous consistency, rather like frog spawn (which
it certainly was not as it was found 25/12/09). Blades of grass were embedded in it, as though
the jelly had welled up around them, rather than being flattened as by
it being dumped from above. No other such dollops were in evidence.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

  • Unidentified fungus/slime mould/alga?

This looks similar to the 'Wierd Slime' I found (see http://www.ispot.org.uk/node/10095). This sparked a few comments and possibilities, but no sure-fire identifications. Clearly different instances of the slime may well have different plausible explanations ('Nostoc', slime moulds, jelly fungus etc), but see also the Times online article - the stuff in this was apparently tested for DNA with a negative result....http://www.timesonline.co.uk/tol/news/uk/scotland/article6840730.ece

I don't think that it is Witches Butter. Compare the picture of that species here: http://www.ispot.org.uk/node/15391

It looks closer to Gloeocystis, an alga. See http://www.ispot.org.uk/node/10098

Frost damaged?

I found very similar looking slime on a large rhododendron tree a couple of weeks ago. Further along the same branch was a fungus that appeared half-converted to slime, given the weather I assumed that the fungi had been frozen and the slime was what was left after it thawed out - a case of severe 'freezer burn'.

What did the part that was not converted to slime look like?
