When: 2014-07-07

Collection location: Somerset Co., New Jersey, USA [Click for map]

Who: I. G. Safonov (IGSafonov)

Specimen available

Notes:
A single firm and robust basidiocarp growing in grass under old oaks.

The cap surface is dull, a dense whitish pruina is visible under 7×. The cuticle barely peels. The cap margin is not lined. The gills are forking only at the juncture with the stem.

The taste is slightly bitter. The odor is nill, but the exposed flesh smells like beer. The context is firm, but has the consistency of a marshmallow.

The spore print appears white (not enough for en masse deposit though). The spores are mostly sub-globose, 7-8.6 × 6-7.4 um, sporting a well-developed partial reticulum. The warts are 0.5-0.75 um tall.
