Growing on rock on the shore where often washed by high tides. Black tufts rather crumbly-looking, slightly springy to touch
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
It doesn't appear to have the branched structure of Lichina. I'm leaning towards Leptogium plicatile or a Collema sp.
I think Leptogium plicatile is a reasonable suggestion, but microscope work would seem to be needed.
Collema and Leptogium species can grow on seacliffs and coastal rocks where conditions are damp and probably at least slightly calcareous, but I wouldn't think they would be washed by waves - often in side gulleys where there is no direct wave action.
Not Lichina, anyhow, and not Collema auriforme I feel pretty sure.
Thank you for telling me where I might expect to find these two. It will soon be high tide at the time of day I usually walk by this place, so I can check and see just how far up the sea is coming. There is a lot of freshwater draining off the land at this point too and loads of what to me looks like seaweed or some other form of algae (something I have yet to learn about). It may be that the sea only reaches this point at more exceptional high tides or when we have a strong onshore storm.
It looks most like the photo by kharga on 06/08/11, but not like the other posts for this lichen.
Thanks for pointing me in what may be the right direction, Nigel.
I don't think this is the right direction, but I'm not sure what is. We'll have to hope for expert guidance.
Thank you, Nigel. I'll wait and hope for an identification.
