Observation 214849: Crepidotus nephrodes (Berk. & M.A. Curtis) Sacc.
When: 2015-08-27

Notes: About 2-2.5 inches across. Growing on hardwood.

Almost non-existent lateral stem.

Serrated gills.

Medium rose brown spore, see photo of spore fallen on adjacent cap.

Cap white – maturing to golden brown. Fibers on surface. striate edges.

NOTES:
The minutely spiney, round spores and spore size seem to point to C. Applanatus, but not the brown fibers on seen the young cap.

The pileus fibers point to C. mollis, but the spores of C. mollis are elliptical and smooth.

The cap size, “margin translucent striate”, spore size and shape point to Crepidotus maculans, but not the tan color with dark fibers of the mature caps. http://www.mykoweb.com/...

Certainy appears to be Crepidotus, but not a match to the NA species There are other possible NA species.

Update 2: Found a key to NA Crepidotus here
http://www.mykoweb.com/Crepidotus/index.html

There are other possible NA species.
