Observation 167373: Punctelia rudecta (Ach.) Krog
When: 2014-06-14
No herbarium specimen

Notes: At first I thought this may be an example of Parmelia sulcata. But there are very few rhizines; after examining several lobes peeled from the tree, found only two rhizines. I was hoping to ID the type of lichen used in the construction of the lichen-covered bird’s nest seen in the linked post (166988).

Thought it was the type posted here, but comparison with a few pieces pulled from the nest shows a marked difference in numbers of rhizines.

Yes, the rhizines are different (short and unbranched in Punctelia, longer and with lots of side-branches like a bottle-brush for Parmelia). The other important character here is that Punctelia has dot-shaped markings on the upper surface instead of the irregular or linear markings of Parmelia.

Thanks zaca.

I’m trying to determine if the Blue-gray Gnat Catcher that built the nest seen in the link below targets one specific lichen species as a material.

Evidence seems to point toward this bird being a good little lichenologist.
