Observation 14674: Peltigera membranacea (Ach.) Nyl.
When: 2008-11-27
No herbarium specimen

Notes: There is a problem with this collection: it is not known to occur in Oregon. But the description in Mosses… and the photos in Brodo match so closely, I think this must be a match. I think the range just got extended.

That species is more shiny, and the rhizines are very different (black-tipped and in concentric rows near the margin). It could well also be P. cinnamomea (especially given the brownish tinge to the upper surface) but I think the rhizines that are visible are more typical of P. membranacea.
