Hello Everyone,
I am not certain about the ident. of this species (Image link below). I suspect it is Cetraria merrillii. Any thoughts?
The thallus is 2.5 cm long and 1.5 cm wide.
The largest apothecia is 2 mm.
Photobiont is green algae.
There are smaller branching lobes mostly at the margin of the thallus but not limited to the margin.
The thallus is black when dry and dark green (olive) when wet.
The thallus and lobes are also flat.
This specimen was collected near Cave Junction, Or.
Associate Species:
Letharia columbiana
Nobobryoria abbreviata
Nobobryoria oregoana ??
Vulpicida canadensis
The first 15 images in the album is of the thallus dry. The images after are the thallus wet. The final three images are of Cetraria californica for comparison and contrast.
Is there agreement that this is Cetraria merrillii?
Here is the link to the album
