C. peziziformis should be verrucose. I don’t see it here. But I also don’t have an alternative. Then again, I’m not really an expert in lichens.

This is an unusually difficult case

I bet this has been stepped on a few times in the years past. The C. cristatella, for example, is very badly misshapen, for example, but there is nothing else it can be with the continuous cortex and red apothecia. It is also generally helpful to see the basal squamules that go with each type of podetia… but in a sample so densely packed like this, there’s no sane way to decide which squamules belong to which podetia. This is just a difficult one all around. We’re lucky to get as far as we have.

PS. the brown apothecia: the other problem, if I’m seeing it right, is that it has granules/soredia on the podetia, and C. peziziformis should be verrucose maybe but continuously corticate.

That single apothecia

seems to be it giving us a rude symbol. I agree it seems to brown for many of the species I find in Brodo. Similar, but not the same.

It took me quite a while to see the C. rei and C. chlorophaea group. But I am seeing – finally. You’re right: I was thinking along C. peziziformis. But neither can I find an appropriate Cladonia to match the darker brown. I thought the red apothecia would be an easy match, but NO. Still … fascinating group, lichens. The more you peer, the more that’s there.

Yes, apparently!

Cladonia like to grow mixed together. All part of the challenge!

Turbinate brown apothecia… If it were pale brown it could be C. peziziformis, but it’s not particularly pale. So maybe C. cariosa? Maybe it’s a fertile C. coniocraea?? I think we’d need more material to tell.

looks turbinate to me. It also looks out of place here. Could there be multiple Cladonia species in such a small space Jason?

All of the above!

I see at least C. cristatella (red apothecia), C rei (the tall narrowly “crowned” sorediate podetia), C. chlorophaea group (irregular cups with very coarse granules and brown pycnidia). I’m still debating the stalk with the large brown apothecium, maybe it’s part of the chlorophaea thing…
