Same hillside, different area.

This is the same hillside, but on the hillside there is an area of spruce and fir, that is surrounded by a mixed forest of oak, beech, fir. And in between both places are random sparse hornbeam. I kinda believe at this point, the spruce-fir area was a farm and field like 60 years ago or more, but abandoned, and the spruce were introduced in the field. Spruce doesn’t seem to be natural in other places on the hillside. Anyway, the two obs. here were probably 100m apart or so. For myself, I would believe more that these are the same species, than there is yet another unknown grey Tricholoma species on the hill. Or at least I’ll believe that until I see more, with some other evidence that there should be another grey Tricholoma in the same area.

You described the habitat differently in obs 85801.. If it’s the same area, I agree that this could be squarrulosum too.

Oh, yeah…

Yeah, I meant to go back to this one and change it. I think this was a first siting for me of this species:


Since I’ve now seen some much better examples of this other grey Tricholoma on that hill side, then yeah this one is clearly not T. myomyces. After putting up obs. 85801 I meant to go back to this obs. and change the name, but didn’t get around to it. Here you guys have gone and done it for me. Geeze every little detail eventualy turns up here it seems, need to keep on my toes better perhaps.

But if the other obs. looks to be Tricholoma squarrulosum, then so should this one.

Confusing names

In Funga Nordica:
T. atrosquamosum and squarrulosum are separate species (atrosquamosum with conifers, squarrulosum with deciduous trees), and what we used to call squarrulosum earlier, with greenish hue and growing with Picea, is now olivaceotinctum.
T. orirubens and basirubens are both found in deciduous woods. No news there.

They have also split triste into two smallish species (none of them over two inches broad), triste and bonii, both with conifers (and possibly hardwoods..).

I don’t know what to think – I’m still finding species in this group that don’t fit any description perfectly.

I would also tend to call this

Tricholoma squarrulosum. I do not know Tricholoma triste though which is said to also have a scaly dark stipe.

but the gray an scaly stem is not a character for myomyces (which I prefer to call “terreum group”, btw).

That might be…

Well, that might be. But I think this one was rather old, there was a number of old stuff on the hill on this day. T. myomyces is rather common on the hill, in many places, so I think it is rather probable as an id I think. As for strange odors, I was just getting started on a 3-day sick, with sore throat and stuffed nose, I am not sure I could smell the odors this day. I found more which is more clearly T. myomyces the next week, which I’ll get around to posting at some point.

looks more like Tricholoma atrosquamosum (var. squarrulosum). Did you notice any particular smell?
