Observation 13480: Dendrographa leucophaea (Tuck.) Darbish.
When: 2007-02-25
No herbarium specimen

Notes: These cool octopus-like things were growing on the rocks above Sealion Point, easily accessible from the trail. The rocks are fully exposed to sun, wind, fog. However this lichen tended to grow on the somewhat more sheltered north to northwest, slightly overhung faces.

Here’s the question of the day: is this really the same species as the ones growing on trees not far away on Cypress Point?? (See observation 13476 and observation 13478.) I can find no mention of other Roccella species (sensu lato) in this area, so I can’t imagine what else it could be. (The forth photo does look a bit like the others.)
