I don't suppose may people spend their time photographing cow dung! Ah well.....I do. This is a Dung Fungus, Coprobia granulata, which grows in clusters on cow dung that has been left for a while until it's a bit crusty. The biggest of the discs in this picture is about 2mm across. Fascinating eh?
@ziggy77@rupert@dmcoile@777margo thanks for the comments @hilarymeme - yes they do look a bit like venus flytraps! I can't find any material online that describes what the "eyelashes" around the rim are for - but I would imagine they are probably an aid to trapping spores and guiding them onto the fertile surface of the disc.
...or is it.
