Recognized by sight: with black pine in pure coniferous forest but I think this is a superfluous variety.

What further is interesting,

I summed up two collections here, from same day same wood but within a few hundred meters away from each other. The light colored and the dark colored so it could even be possible that we deal with two species here. BTW, in Breitenbach & Kränzlin, Champignons de Suisse, the photo for T. viridifucatum is nothing else but a “normal” T. sejunctum.

to call viridilutescens is here:

Besides growing with spruce, it has a different shape of the stem, and a softer texture.

I wonder if your collection has a proper name at all. What I have read about T. guldenii(=luridum) doesn’t seem to match either.

I’d love to see a DNA investigation on this group!

I know T. viridilutescens

and believe it to be under spruce. I will post photos when I come to them again.
T. arvernense I have seen twice in Czech Republic and Austria, it is with reddish tints and very difficult to distinguish and too rare to really get to know it well.
There are a lot of other similar ones and as you said a tohuwabohu of names.
As far as I know this var. coniferarum could be integrated in type variety for the only difference seems to be the growth under conifers instead of hardwoods but I have no idea about DNA sequences and the like.

This is an interesting one

I have found a similar looking one on Gotland, and with the help of others named it T. viridilutescens, but I suspect that it contains two species, this one with pine and the other with spruce.

I don’t know what Tricholoma sejunctum var. coniferarum is (at least not a synonym to arvernense). This is a difficult group with so many confusing names…
