Thanks for adding another location! The margins are pretty irregular in this specimen but looking at the habitat shot, it sure looks like N. homalea. It's also neat to see a few smaller thalli colonizing that rock. This might be a fun spot to revisit later to see if you can pick out how much those smaller thalli have grown over time.

on coastal rock, not sure if this is N. homalea... the margins are irregular - with some interesting clumpy features (?) @sbenson - for your Fog lichen project?
