Two of these growing in damp mixed woods near pine, with caps and bases of stems both fused. Brown cap but lemon-yellow pores!

Closest field guide match is Boletus ornatipes, but it indicates that that normally has a yellower cap. But it’s the only one described as having lemon-yellow pores.

MushroomExpert.com describes B. ornatipes as having a dull brown cap variety.

Both sources indicate it associates with hardwoods. Though I found it near mostly pine, there are hardwoods mixed with the pines, mainly birch and maple but possibly including beech.

The Bessettes’ big bolete book shows both Northern and Southern forms of this species, with the Northern having a more pale brown cap. Looks like a good fit to this Ontario bolete species.

I felt that Retiboletus ornatipes was not quite a perfect fit, as the stem didn’t seem “ornate” enough. However it was the only bolete with truly lemon-yellow pores in my field guide. I had a look in its index and B. subglabripes isn’t even mentioned in it, let alone depicted.

I wonder if there is an online “field guide” that is more complete, lacking the size limits of a printed book. There are certainly sites like mushroomexpert.com, but these mostly do not seem designed to identify fungi but to provide information regarding already-identified fungi, along with ancillary information and advice.

What’s really needed is a kind of key or database, preferably with an interactive interface. A wizard like questioning interface makes sense. It could ask questions about your mushroom, to which you could provide answers or “I don’t know”s, and at the end it might cough up a list of possible species, which would obviously tend to be large in some cases (LBMs with no spore print, in particular). Of course some things would have to be construed fuzzily. It would be better for it to be over-inclusive, so any narrow identifications made are very likely to be correct.

Existing keys for particular families and genera would be an obvious source to draw upon in constructing such a tool.
