Hey Noah,

No, didn’t taste them this time around, but from the two encounters I’ve had with this species(both same time of year) they were very bitter. B. abieticola seems to have a much redder, tanner cap appearance than the buff, almost light suede look of B. coniferarum. From all fruit bodies in this collection I should have def cut the young one in half, and tasted it like you suggested. Either way, I’m pretty sure this is B. coniferarum based on all other key factors and development of mature specimens.

Are you coming West for the foray at Mt. Rainier this season?

Let me know and we can possibly meet up in October :)

Thanks again for all your help, support and advice at MO.

Did you taste them Drew?
