Thanks, Chris. Any possible differences resolving along habitat lines are simply possibilities at this time. What I saw, long ago, planted the seed of a question. Now A. thiersii, often with pines, has been clarified out of “A. subrutilescens” in an old, collective sense. There may be other similar things still awaiting clarification (esp. with alders on the Northern CA coast, perhaps with oaks near Santa Barbara).

Unfortunately, I didn’t collect anything and I’m back in Utah now. I wasn’t aware of the differences in A. subrutilescens for alder vs. conifer habitats, but I will look for specimens in the future.

Kauffman originally described the species from two habitats, one of which was among alders along the coast. Sometimes the alder forms look a bit different from the classical ones with conifers in the Coast Ranges. Someday, someone will get some ITS DNA sequences from specimens under alders (hint).
