Observation 57906: Peltigera membranacea (Ach.) Nyl.
When: 2010-10-15
No herbarium specimen

Notes: Other photos of Peltigera on MO resemble P. horizontalis and P. neopolydactyla but given its orange fingers, I’d vote for the latter. Found near the Big Cedar Tree, south of Hoh valley, just inland from the National Seashore.

Recognized by sight: When wet this species often looks hairless, but those sharply-raised narrow pale veins forming a diamond-like network is very typical for P. membranacea and rule out the polydactylon group. Also, the brown finger-like apothecia rule out horizontalis group (flat apothecia) and neckeri group (black apothecia).

Jason,

Thanks for the update on this observation. I especially appreciate that you explained how you came to your conclusion as many observations just leave it at “recognized by sight” – good for the person who already see’s the clues, not so helpful for others like me.

It’s a striking looking lichen to find.

thanks again,

adam
