Observation 22207: Parmelia saxatilis (L.) Ach.
When: 2009-06-12
Herbarium specimen reported

Notes: This is the common species on rocks, although it is usually really ragged, so this seems to be the very first time I’ve ever collected it…

If the isidia are more sorediose (“soft-corticate”) and less well-formed, then it might be either P. fraudans (rock) or P. hygrophila (trees).
