When: 2009-07-09

Collection location: Edgewood Blue, Wells Gray region, British Columbia, Canada [Click for map]

Who: Jason Hollinger (jason)

Specimen available

Growing on ground near doug firs. Taste and odor mild. Spore print ochre.

Update: Spores spiny, 7.5-8.5 × 6.5-7.0 µm, spines ~0.6 µm.

Spore print.

grows Russula postiana with variable cap colour, mostly some kind of green. Stem very fragile, and taste mild. Spores with rather sturdy warts and few connections. Just a thought.
