Description:

Found growing on same rock as Aspicilia contorta subsp. contorta (per AlanS in my previous posting) but this seems to have more of a thallus than that specimen. If anyone can confirm/suggest otherwise, many thanks.

Identifications

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

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

Species interactions

No interactions present.

Yes, definitely maybe ...

On balance I would call this subsp. hoffmanniana, though I think they need more study. They certainly appear to grow together.

I used to look at them on a concrete wall capping just outside work and periodically reassure myself there were definitely two taxa, but then the wall was replaced!

But there is continuous thallus to the edges of the thalli, so I agree. I think.
