When: 2011-08-16
No herbarium specimen

Notes: Collection includes specimens at various growth stages, with macro differences seemingly correlated with age of fruit bodies.

Cap: dark and minutely wrinkled in young one, minutely cracked in mature one, rimose in old one.

Pores: whitish on young one with dark brown bruising, dingy yellowish on old one with blue bruising that mixes with red and finally balckish.

Stipe: densely and darkly punctate/pruinose on young one, dark punctate on mature one, coarsely reticulate on old one (which came as a surprise to me).

Context: white. Bruising: light blue and then slowly to red on young one, blue then red on mature and old ones. Cut context on all eventually blackish.

On lawn 2-15 feet from woods which feature a few fast growing oak saplings.

with exposed context inside some wax paper, and the paper stained blue… sort of a turqoise blue.
