Observation 14547: Phaeocollybia kauffmanii (A.H. Sm.) Singer

When: 2008-11-23

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

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Specimen was dropped near the highway, sliced at the bottom, and probably a good idea. Phaeocollybia are poisonous. This specimen is dark ruby-red on top, with rusty-red gills, and a fibrous, hollow stipe. Haven’t sliced the stipe open. Am currently drying it with hopes of getting a positive identification at tomorrow’s Oregon Mycological Society meeting by Dr. Lorelei Norell.

Used references: Arora’s Mushrooms Demystified, p. 416. I’m not sure this is exact, it could be P. oregonensis, but I don’t have a microscope to check the spores with. It is, without question, one of the largest Phaeocollybia I’ve ever found or seen, so Giant Phaeocollybia seems at least a good general fit.
