BLS dot map Ramalina pollinaria s. lat. (Blue = 1999 or earlier & Red = 2000 or latter)
Finally I have found some myself and could compare the material to Gasparyan et al (2017). During a weeks holiday in a cottage on the side of The Striperstones, I picked up my first collection of Ramalina pollinaria s. lat. from the branch of Holly in moorland near improved fields. This formed a beautiful mat along the branches with the thin branched thallus ending in spine-like branchlets. The latter ended in small nodules, from which the punctiform soralia develop. The soredia were granular 50 – 60 µm diameter.
Scans of specimen
The species are morphologically distinct, with the soralia formation and distribution the most distinctive features and, as the spine-like branchlets with solaria developing at their tips are the main defining feature of Ramalina europaea, so this looks very much what I have got
Excerpts from paper:
The description on the LGBI includes the following
The first half is certainly description of Ramalina europaea, the latter could be of Ramalina pollinaria s. str.. We certainly have Ramalina europaea and it is likely we also have Ramalina pollinaria s. str., as Gasparyan et al (2017) record this from The Netherlands. So do keep a look out for Ramalina pollinaria s. lat, at the very least the lack of recent records points to a serious decline, either in the species, or in recording it, and that needs sorting out! Gasparyan et al (2017) recorded Ramalina europaea from both rock and bark, while they only recorded Ramalina pollinaria s. str. from bark. The LGBI implies that Ramalina pollinaria s. lat. was mainly recorded on rock, so it may be that most British and Irish records refer to Ramalina europaea.the apices dissected with many small, nodulose proliferations, or more flattened branches with wavy or deeply incised or notched margins
