found on an old branch. has shallow cup shaped discs.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Looking again, I'm not convinced that the warty bumps are soredia or isidia now, so I've agreed with your ID to cancel out my own.
This is difficult and the DNA people maintain that U. florida and U. subfloridana are a single species. But how carefully did they compare DNA and micromorphological characters of each sample??
Here, there are, I think, a very few isidia (or 'isidiomorphs') along the branches from the sides of the apothecia, but other branches are smooth, and I don't see an approach to the fertile state of U. subfloridana, which has these branches strongly isidiate and has a much more untidy appearance.
