examples with stipe completely pale and relatively lacking in scruffiness are more common than I had thought.

B. hortonii occasionaly has reddish tones near the base; not always. In any event it is a nifty looking mushroom, and I’m looking forward to eating it.

has been that, except for the deeply wrinkled cap, it otherwise resembles B. subglabripes. So the whitish stipe without reddish dots/scruffiness is a bit different than what I’d expect. But the other observable traits (including the blue-green ammonia flash on the cap) match very well with hortonii.

My one spot for this type is an oak/hickory dominated hardwood forest.

Here’s another recent post… with a rather pale unadorned stipe obs 169092
