Confidence: I'm as sure as I can be.
Notes: These are the same as my previous posting ;
Cladonia polydactyla was suggested but these do not seem to have the "squamules, often orange-brown towards the base on the underside" nor the "bright red apothecia" as these had brown apothecia. C.fimbriata was also suggested but these seem too "coarse" compared to that species. Hoping someone may come up with an answer but I am aware just how tricky they can be! Thanks.
