Observation 23219: Hypogymnia inactiva (Krog) Ohlsson
When: 2009-07-15
No herbarium specimen

Notes: Older specimen, well dried out, blown out of Noble fir (Abies procera), and bone-dry, even though the area had nearly an inch of rainfall 4 days ago. Interesting cups. May be Hypogymnia physodes, but would appreciate any other opinion.

Larch Mountain

is about 25 miles east of Portland, along the Columbia River. Specimen is near the top of the mountain, which is, according to maps, 4056 feet high. It is an odd location with many of the characteristics of both the coast and an alpine environment. Western azalea, which is almost exclusively found within a mile of the Pacific Ocean, is also found near the top of Larch Mountain, some 80 miles inland from the coast by line-of-site, or 110 miles inland via river miles. The top of Larch Mountain is also the top of a trail which leads downward to Multnomah Falls, will plummets into the Columbia River Gorge a few miles east of Corbett. The Columbia River at Multnomah Falls is still considered tidewater, and Larch Mountain is the first tall peak in the Cascade Mountains from the Pacific Ocean.

Looks like Hypogymnia inactiva

H. physodes would be sorediate and not apotheciate. I’m told H. imshaugii and H. inactiva look very similar, except that the latter is black inside the tubes if you tear it open. H. inactiva is supposed to be a coastal species — is this near the coast?? Might also consider H. heterophylla, but that one is more common down south. It would be more irregular and sprawling.
