Found on wood at Longshaw Estate, Peak District, 3/3/16
Identification attempted using Frank Dobson’s book (new edition).
Colour: yellowish rather than blue-grey
Soredia: all of podetia finely sorediate or finely squamulose
Podetia surface texture : as above
Podetia branching: very scarce
Cups: just one small cup of C. fimbriata (wine-glass) shape
Basal squamules: matted, up to 2 mm, incised, white below, not curling
Apothecia: few, largish, translucent pale brown
Split along podetia : not seen
K -ve
K+C -ve
Based on the largish, pale brown, rather translucent apothecia I keyed this out as possible Cladonia ramulosa.
