The height of pictures 2 and 3 is 24mm; the lichens were growing on the twigs of an ash tree
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
I was not sure if it was part of a lichen but now I see it is not. Thanks.
Did you touch the pink blobs? If so, were they very soft or were they rigid and holding their shape?
I don't think it is possible to tell from the photograph whether they are Illosporium christiansenii, as claimed above, or the sclerotia of Marchandiomyces corallinus, which can look identical until one pokes them.
Since they have held their shape in the rain, and the blobs of Illosporium christiansenii are merely piles of conidia that begin to disperse with the slightest touch, I favour this being Marchandiomyces.
Compare http://www.lichens.lastdragon.org/lichenicolous/Marchandiomyces_corallin... (lower photographs on Physcia aipolia, and imagine them wet).
Both species parasitise Physcia tenella.
Also, in the wet:
Thank you for the identification. I seem to remember them holding together well.
I'd not noticed this comment before. It makes me wonder if my observation at http://www.ispotnature.org/node/462715 has been misidentified. The pink structures in that observation were certainly not inclined to disperse even with my clumsy attempts to move them around to position them for a photograph.
