Observation 118278: Alyxoria varia (Pers.) Ertz & Tehler
When: 2012-11-28
Herbarium specimen reported
0 Sequences

Moderately open mixed forest, ca. 200m elevation, on trunk of very large Populus trichocarpa, about 1.5m above base. I was amazed at how large of an area was covered by this lichen, perhaps 2 meters square, and more patches were visible higher up. It seemed quite attractive to me.

My specimen is very small though, just a few tiny pieces.

This is certainly an impressive colony of it by any standards!

probably relatively common

There are 13 specimens at UWBM, mostly collected by Mildred Arnot from bark of Acer macrophyllum in low elevation forest in Snohomish Co., which leads me to believe that it is probably relatively common in low elevation forest elsewhere in western WA. (I had previously collected a less impressive specimen from the Middle Fork Snoqualmie.) Think I’ll look out for it more now.

Is this common in you area?

I’ve always thought of it being an eastern thing… oh but there it is, Brodo shows a splotch around the Puget Sound. Interesting! And not just a weird accidental occurrence barely surviving, this thing’s thriving.
