1 Apothecia brown 10 Primary thallus squamulose. Podetia prominent or not. 11 Thallus of podetia or podetia growing from basal squamules. 12
Thallus with podetia which are not usually interwoven, sparsely or not branched, and which may have a cup at the tip. 32 Some podetia with longitudinal splits
33 K-, Podetia with soredia and squamules UV - ice blue - Cladonia glauca
Cladonia floerkeana
Cladonia Sp? 
Cladomia Sp?
All forms of Cladonia chlorophaea???
From the Norfolk Recorder
This one showed negative spot tests and UV blue/white thus Cladonia crispata (Although a very small specimen)
Again from the recorder, despite the brown colour of the cups
the spot tests were P+ red, K-, & UV- so they rest at C chlorophaea s. lat
