Observation 169616: Russula virescens group
When: 2014-07-07
No herbarium specimen

Notes: A single fruiting body growing on moss/grass under old oaks.

Spore measurements:
[20/1/1]; L x W = 7 – 8.1 (-8.4) x 4.7 – 6 (-6.5) um
L x W = 7.6 × 5.3 um
Q = 1.43

I am still having a tough time distinguishing this one from R. parvovirescens morphologically. The spore range for the two have too much overlap, though the latter has somewhat larger spores.

The spore ornamentation ranged from no connectors to a partial reticulum, which is consistent with the description posted on mushroomexpert.com.
