Notes:

Stem, 3-9 cm long , by .5 to 2.5 cm., some growing together. Becoming a little hollow. Ring zone, fibrillose.
Flesh white to light brown, with little color change to brown, no traces of purple on the whole mushroom. Base mycelia appears yellow.
Odor, mild, not unpleasant, maybe like cedar.

Spores, amygdaliform, slightly ovate, finely verrucose.
