Melanohalea exasperata
Foliose lichen. Thallus olive- to red- or dull brown, matt to moderately shiny, surface with abundant and very evenly distributed, minutely flat-topped papillae (warts) (not breaking away so technicaly not isidia, though the tops may lose their cortex to form pseudocyphellae); apothecia frequent, sometimes abundant enough to obscure the thallus, moderately large, with brown to olive discs and distinctly papillate (warted) margins.
On branches and twigs, very rarely rocks.

8~] thanks Arlanda. You're amazing.
Well Mark, apparently, the scientists decided that two species from the genus Melanelia should be countetd as different genus: Melanelixia and Melanohalea, both Melano because they come from Melanelia, Melanelixia dedicated in honour of John A. Elix for his immense contributions to lichen
systematics and chemistry, especially in Parmeliaceae and Melanohalea in honour of the father of modern studies on the Parmeliaceae, Mason E. Hale
jr.
Scientists! They can take the fun away from anything! I still do not know the reason for exasperata!!!
Wow you're right... black* exasperation :-) (does the *halea bit mean anything to you in Latin?)
I agree Mark. But look at the Latin name, exasperated?
I can't suggest a better name for this one. :-)
