| | | Lichen ID, Peltigera horizontalis?
Don't often do lichens, but this caught my eye this afternoon. Growing on a mossy boulder close to a stream in mid-Wales. Orange-brown bits (excuse the technical terms  ) look like Googled photo's of P.horizontalis but I really have no idea.

What about Peltigera membranacea?
Just been identifiying some of my lichens, and theres something similer on Alan silverside lichen site.
Regards Chris. |

Regards Chris. | Thanks Chris,
That does look a better match, especially as the sample I kept has dried ash-grey rather than dark as a P.horizontalis is described as doing.

No prob Gerel.  Lichens are tough little blighters to id, so we may both be wrong  |

Certainly not horizontalis. AlanS's site remarks on dark veins on underside, which your photo doesn't show. Apothecia are not the right shape either. I'd agree that membranacea is most likely.

Thanks guys,
I'll re-label the photo's as probable P.membranacea.

Where the tips of the thallus lobes have dried slightly, you can see the tomentum.
So yes, it is Peltigera membranacea - well represented.
