Re: Cladonia's ...

Hi JP

Cladonia coniocraea looks a very good suggestion, but there are two or three others I cannot rule out. It would have been useful to have seen the detail of the tips of the spikes (podetia). Some of the red-fruited species can look very similar at this stage, but usually have minute red pycnidia.

Also, the material is very saturated and a much brighter green than it would be under normal conditions, which means that the usual colour clues do not help.

The podetia are covered with powdery granules (soredia), which cuts down the possibilities, but as well as C. coniocraea, it would be possible for this to be one of: C. polydactyla, C. macilenta (both drying very grey), or the rarer C. umbricola, or maybe others I have not thought of.

So sorry I cannot be 100% positive on this. C. coniocraea is most likely, but it is all too easy to be caught out.

Alan
