Observation 85801: Tricholoma squarrulosum Bres.
When: 2011-11-12
Collection location: Thoiry, France [Click for map]
No herbarium specimen

Notes: Found under oak, beech, fir.

I’ve been dismissing all grey Tricholoma on this hillside as just another T. myomyces. But these are clearly different now, with the scaly cap and stipe, and the rather dark grey streaky colors on the stipe. I think I’ve got the best name on these? I’m never really all that sure on grey Tricholomas.

and so does Mycobank.
But I still think it’s strange to use a variety name on a taxon if it exists as a species, and that one of the authors of the variety name doesn’t use it himself anymore..

is clearly a species of its own and not a variety.

to deprecate squarrulosum in favour of atrosquamosum var. squarrulosum ((Bresadola) Mort. Christensen & Noordeloos 1999).

First, it makes no sense to use a variety name if it’s meant to be distinguished from the main species.

And second, in Funga Nordica (2008), where Morten Christensen is involved in writing the Tricholoma chapter, they use the name squarrulosum, not the variety name.
