Your observations on the bluing…

match my own. Try checking where the interior face of the tube layer adheres to the inner cap context. This is where I most often see the stain. As you say, it’s most evident on mature specimens.

The reticulations on the ones seen here are not as coarse/prominent as what I see on my own collections.

Not much bluing present

It’s only on some of the more mature specimens that I ever notice some
possibly faint bluing that may be occurring. But it’s not very noticeable and takes some real close observation.

Daniel, did you notice any bluing?

With B. subcaerulescens the bluing, if present, is faint and either on the pores or on the context where the tubes attach to the pores. It’s interesting to me that collections I have IDed as such sometimes completely lack the bluing. I have one local patch that almost always shows bluing and another where the mushrooms have never exhibited bluing.

The ones in this post look like subcaerulescens to me.
