Here is an example…

of what I have called pinophilus.

My reason for using this name is that the account of Boletus pinophilus found in North American Boletes matches my observations very well… dark/complete reticulatum, no bluing, possible association with pine.

Irene, that’s interesting that your pinophilus sometimes stains blue. In my area B. subcaerluescens usually stains blue (context which meets tubes and/or tubes), but it otherwise looks pretty similar to what I call pinophilus. Both types seem to associate with pine, but in areas where oak is also present.

Also interesting… Boletus nobilissimus, an eastern NA King Bolete which occurs in oak/pine woods features a wrinkled/pitted cap. Some really nice ones were collected at the 2012 NEMF foray.

exactly how Boletus pinophilus looks. I picked them for years in Croatia

This Canadian bolet is not close in appearance

I thought someone might recognized the type (After my wrong suggestions)

Interestingly, everyone knows what is not!
Nobody knows what it is.

There are hundreds of them in a small private woods.

thank you very much for trying :) :)

The pinophilus I know

has some particular features that makes it different from other species in the european edulis group.
A “bumpy” cap surface, usually rather dark reddish brown. The surface of the tube layer usually discolours brown and sometimes (not often) also bruises blue.
How does that fit american/canadian obses of “pinophilus”?

But there is a pine-associating…

white-fleshed reticulate eastern bolete that has gone by the name pinophilus. It looks like B. subcaerulescens, except there’s no blue bruising, even in mature specimens. It may be the same as subcaerulescens, but a non-staining variety. Bluing reactions within a given species of Boletus vary from year to year, by season, and by location. Eva, your bolete posted here does not really look like the eastern pinophilus/subcaerulescens.

I believe the name pinophilus has also been applied to a Rocky Mountain bolete. Form what I have seen posted on MO (European material), neither of these NA boletes is likely the same species as the European pinophilus.

Sometimes the dna shows that we have the same species on multiple continents. Other times it indicates that our North American species are different. Regarding Boletus pinophilus, that doesn’t seem to turn up in North America.

(spelling is not my best side)

I’m interested in how we use some European names and some we do not?

The name pinophilus…
By: Dave W (Dave W)

has been applied to an NA bolete. It appears in the Big NA Bolete Book, and I have applied the name to some of my collections. Presumably the name was first applied to Euro material. So we may need a new name for NA collections… that is, if this type actually is something other than a variety of edulis.

I am also not gay.

I swear!

Regarding Boletus pinophilus, that is a European species so I wouldn’t expect it in Canada.

Is it possible to be Boletus pinophilus ?

Eva, this reminds me…

of a red-capped type I have found in an area dominated by birch, beech, maple, ash, and hemlock… no oak. One other similarity is the stipe showing wide reticulations all the way down to the base. One difference is that my collections shows a wrinkled cap surface.
