That is weird, does it have any intact cortex? Gerault’s pictures do have an intact cortex, which does look very Cladonia rangiformis. The Mediterranean Cladonia flora does mention Cladonia rangiformis var. sorediophora, but states it has no phylogenetic significance (that does not mean it it still not worth recording). I have never seen even the more restrained material shown on the lichensmaritimes.org site. If your material has some intact cortex similar to that of Cladonia rangiformis, then it is likely to be this. Not sure what else it could be.

Missed that photo; not much cortex left, so not much got further there. The only other possibility from the habitat, would be Cladonia furcata subsp. subrangiformis (basically a morph of Cladonia furcata found on calcareous soils with the podetia distorted by large calcium oxalate crystals) with sorelia I suppose, but this would not be densely branched.

Yesterday I got some sorediate Cladonia furcata on the New Forest:

This does not look much like yours so Cladonia rangiformis seems most likely

PS the mushroom Arrhenia peltigerina parasitising Peltigera hymenina is popping up widely in the New Forest now; appears to be having a good year, so worth looking out for spreads of dead Peltigera hymenina with the Arrhenia peltigerina fruiting bodies associated see https://britishlichensociety.org.uk/resources/species-accounts/arrhenia-peltigerina” class=”bbcode_url”>https://britishlichensociety.org.uk/resources/species-accounts/arrhenia-peltigerina.
