Seemingly a moss in small mounds growing on limestone outcrops on high ground in Derbyshire, not mountain, but high pasture.
No identification made yet.
No interactions present.
It is a green alga, Trentepohlia. Several species.
Thanks for that, having looked at Trentepohlia species it looks like it could be aurea.
Thanks again for putting me in the right direction :-)
I doubt you can say it is 'possibly T. aurea' anymore than 'possibly T. anything else'. You need a microscope to examine the cell structure to separate the species.

High pasture, with limestone outcrops, the area has been mined for lead in past centuries.
