Observation 18165: Boletus subcaerulescens ( E.A. Dick & Snell) Both, Bessette & A.R. Bessette
When: 2008-08-25
No herbarium specimen

Notes: The cap colors varied for these. Some showed the reddish brown to rusty brown listed by B/R/B. But a few (growing in the same patches) were more yellowish. It is possibly that the yellowish ones are a different species, byt the other characteristics which I listed were observed on the lighter specimens. (For at least some mushroom species sometimes cap color varies with available sunlight.)

I check this collection site almost weekly, and have seen it twice in 20 years. So it appears to be uncommon. I think I may still have one dried jarful of only this type.

Fixed dates…

as admin, I went in and changed the dates for the observation and the associated images. Cool bolete by the way!

This was the second time I found this type…

in this same spot. The first time was in the 1990s. Neither collection showed any bluing. I also made one other similar collection in the general area (Seven Tubs Natural Area) which did not show any blue. Except for the complete lack of bluing, these do look like B. subcaerluescens. The habitat is similar to another spot where I have made several collections of B. subcaerluescens which did show variable degrees of bluing; 2 or 3 needle pine, oak, and also in the case of this obs, hemlock.

I believe that “pinophilus” is (also?) applied to a western NA bolete that appears to be much different than this type. I have seen a few obses here on MO of SE NA material (Florida or Georgia) which seem similar to this obs, collected near pine.

I do not recall whether or not the reticulations darkened when handled, as per the description of B. pinophilus in B/R/B. But the one photo shows dark reticulations. Macrocharacters for this collection match pretty well with the description in B/R/B.

Perhaps what B/R/B calls “pinohilus” is a non-staining variety of subcaerulescens? Some other Boletus species exhibit variable bluing.

I am unable to correct the collection date, as the name “Dave in NEPA” (a name I formerly used on MO) is no longer active. Correct date 8/25/08.

Also in desperate need for a proper name!

Has nothing to do with the European B. pinophilus.

You can change the date for this collection by directly editing the observation.

Forgot to enter the correct date when the shrooms were collected… 8/25/08.
