Growing under beech. The largest specimen does have some yellow at apex of stipe. Ammonia reactions are negative on pileus and stipe, but do produce a red reaction on pore surface and a lesser red reaction on tube surface. Some very light, white reticulation at apex of stipe.
I found this same mushroom last year and was thinking it was B gertrudiae, but was also on fence with B nobilis. Looking for opinions, please.
