Not 100% on which Cladonia species this is so any comments will be much appreciated, thanks. Found growing in damp moorland.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Tricky. C. subulata and C. glauca seem the likely suspects.

More likely C. subulata, but time to get out the chemical kit.

I have never seen either

I have never seen either Glauca or Subulata with those 'growths' on the edge of the podetia before, also the brown apothecia so I ruled those species out to be honest.

Thanks Alan for your input on this one.

I have had a lot of trouble with C. subulata. In what I think of as its typical form, it is a graceful species, scarcely to be confused with anything else one might think. Yet it does show a surprising range of variation, and sometimes peculiar features.

Arguably the best current field lichenologist in Britain tells me he cannot separate C. subulata and C. glauca, and while this might be a rather sweeping statement, there is good basis for it.

In turn, C. glauca shows morphological overlap with the rare C. rei, though DNA studies have confirmed they are separate species.

Looking at the photographs here again, I now favour C. glauca very slightly, but I don't think a positive ID is possible either way, just from the photographs. I am not bothered by the "growths".
