Vaguely globular heads with 2- or 3-branched tips make it either C. portentosa or C. mediterranea but the latter is confined to The Lizard in Cornwall, so C. portentosa it is.

Fruticose Cladonia

Absolutely - this is one of the few Cladonia species to have a fruticose shape - it is quite common and may be put in the subgenus Cladina. There is a handy little book called 'Cladonia: a field guide' by N.G.Hodgetts ISBN 187370108X which I think is still in print and in my opinion is worth the few pounds if this is a group of lichens you are interested in.
