When: 2008-10-02

Collection location: Larch Mountain, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Usually I’m bad at keying out Amanitas. But this one was a near cinch with the yellow annulus. Found 2 different specimens which look quite different from each other (pale buff-brown to dark brown), but distinctive yellow annulus on both, and both were in close proximity to each other.

This is a distinctive species…the yellow universal (as well as partial) veil…

also leaves bits of yellow around the base of the stipe. Cap colors, as you noted, can vary from the brightest yellow to the darkest brown, and combinations of the two. The bad news? Rod tells me that franchetii is a gray-capped European species that we don’t actually have here in North America! Sigh. But I, and most others, still call it franchetii, and so can you.
