Observation 18167: Boletus sect. Boletus
When: 2008-08-04
No herbarium specimen

Notes: Just for good measure, here’s another eastern edulis type that comes in a variety of cap colors. These young specimens do not show any of the cracks that sometimes occur on the cap of this species. The stalks within this collection were about 3/4 reticulate, but not extremely coarsely so. These stalks were almost completely white. Note the resemblance to the yellowish specimen of B. pinophilus (possibly) that I had recently posted… and, the resemblance to #18114 recently posted by John Plischke (which I tentatively IDed as B. pinophilus). My main reason for going with the B. variipes ID here, is that these were found in an oak woods (a few hemlock trees). B. nobilis is another good possibility for this one.

I just noticed the other day…

the species name “pseudopinophilus” in The Boletes of E NA. I have wondered for quite awhile… what are these coarsely-reticulated pine-associating subcaerulescens look-alikes (no bluing)?

This obs (18167) is almost certainly not psedopinophilus. Aside from the non-coniferous habitat, the stipe does not show the coarse reticulations. These mushrooms were found in an area where nobilis and separans intermingle, and if that’s not confusing enough, fairly ambiguous examples like these are not uncommon.

Here is another one…

You may want to wish to contact Jimmy Craine (doctorghosty) for a picture of B. pseudopinophilus: http://mushroomobserver.org/observer/show_user/3106. He is one of the authors of this species. Obs 167169 could be pseudopinophilus.

I do not think this is actually pseudopinophilus because of the habitat

BENA specifies that it grows “under conifers, especially pine”. But I was looking for sample photos and realized this new species was not yet on M.O. And this one popped up on the “pinophilus” search.

Consider this a request for folks to go back over some old & frustrating observations to see if they match the new species. The main features seem to be a “conspicuous brownish reticulum that darkens when handled” and is “whitish near the apex”; a cap that is often wrinkled or pitted; with no staining. Other than that is seems to be in the edulis group.
