Observation 111005: Grifola frondosa (Dicks.) Gray
When: 2012-09-23
No herbarium specimen

Notes: Growing at the broken end of a branch of an enormous red oak. The branch retains some slight attachment to the tree. Mushroom is roughly 1 to 1.5 feet above the ground. Underside of caps do NOT stain when poked and prodded. Pores occur part way down stems.

Most authoritative sources describe Grifola frondosa as occurring only at ground level, at or near the base of the host tree. This makes me hesitate to conclude that I am identifying this correctly.

Recognized by sight: My confidence is middling because this is my first G. frondosa find.
Used references: Numerous print and online (Kuo, Volk, Fischer, Emberger, Spahr, and others). Only two of the several sources make any allowance for a G. frondosa up off the ground, so that adds to my lack of confidence.
