Who: Joseph D. Cohen (Joe Cohen)

No specimen available

Substrate: Rooted in soil, pushing into duff at the drip line of a Pinus ponderosa (Ponderosa Pine). (The mushroom raised the duff slightly in a “mushrump”, but itself was completely covered by duff.)
Habit: clump of 3
Odor: hard to describe, perhaps a little like Kosher salami
Taste: mild, hard to describe
Chemical: Both inside and exterior turn dark brown with KOH
Other: Photos are a couple of days old. The mushrooms are getting darker/browner with age. They were lighter when collected. Compare the two cross-section photos to see the difference.
