When: 2011-09-03

Notes: A single basidiocarp growing on moss under old oaks.


The most accurate depiction of the underside and stipe details — taken without a flash and with adjustments to exposure and shutter speed. The grayish-buff pore mouths first stain blue and then red-brown.
Older stains (on the right side) are just brown, and the younger ones (on the left and middle) are still displaying reddish tinges.
The context immediately following dissection
Staining of the context due to exposure to air 5 min following dissection
