Lichen Identification Help Please.

Found this today, growing amongst moss on a fallen Beech trunk, and would appreciate if anyone could offer an ID.

I think

all the photos show the same type of Lichen, but have taken various pics to try to show the different features of the specimen.

Regards
Mike.

I know nothing about Lichen so my input is bound to be disposable

but there look like Peltigera species to me.

Yes, its a Peltigera, and possibly P.hymenina - but that's a very tentative ID!

Another novice happy to be wrong but wonder if those rhizines fit with
Peltigra rufescens.

Cheers J.P.

I agree with Jenny. Peltigera hymenina.
Good to have the underside shown in the photographs, which in this case confirms the diagnostic characters.

Definitely not P. rufescens, which has a minutely but densely pubescent upper surface, and rhizines in tufts (and usually grows on sand dunes or in rather dry, gravelly places).

Thanks everyone, much appreciated.

AlanS - I noticed the underside had some distinctive features which might help ID, so thought it would be worth another photograph.
( This comes as a result of being told to photograph the underside so many times in order to help with fungi ID's

).

Thanks again.

Mike.
