Matted ≠ squarrose

Squarrose in this case means minute side-branches at right angles to the main rhizine. But see comments on other observation: sulcata’s rhizines aren’t always obviously squarrose, in fact sometimes almost impossible to find any that are even faintly squarrose. Says something about the conditions its growing in… but not sure what it says. :)

that doesn’t seem to have squarrose rhizines. They are matted in the middle of thallus, and if someone wants to call that squarrose – it’s fine with me. However, I read that this species is extremely variable.
