Observation 12306: Lichen P. Micheli

When: 2008-10-10

Collection location: Southeast Portland, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

I have finally decided that the dark, nearly black funnel-shaped structures in this photo are actually spore-producing structures. The are perhaps .5cm above the surrounding bark, have a whitish rim on them, and the leafy palmate upright lichens next to them could be some kind of Parmelia, but not, I believe, Parmelia sulcata. Because of the varying height of this species, it was quite difficult to get both in some kind of focus. On the tree both looked nearly pine green, but not in this photo.

That does look different…

You’re right, it’s hard to focus on some of these bushy things. Based on the color (“pine green” implies fairly dark I think), I’d start looking at Tuckermannopsis, maybe T. orbata which is supposed to be common there. It has ruffled/crisped erect margins like that, with low cup-shaped apothecia.
