The stature and thick, grey gills invoke T. atroviolaceum and the pine needles fits fine.

Are you so annoying?

obviously you’d use a separate collection bag for the duff sample.

A few preselected collections of duff will never quite replicate the variety of habitats actually found. If one mushroom is found in pure oak woods and another in oak woods but near a scattering of pines, there’ll be needles in the duff at the latter site, and the mushroom there might be associated with either tree. If you just have a big bag of oak duff, a big bag of pine duff, and a few other things, and the collector just glances around and writes “oak” on the tag, versus actually collecting a bit of the duff, the potential association with pine might never be noticed.

The duff isn’t chosen at random, they have a big garbage bag of each type and they put in the kind of duff that is specified on the tag. Twizzler, it would not make sense to stuff all the mushroom collection bags with duff. The caps are viscid and we have about 25 of them now.

the simplest solution be for each collector to gather some duff from the site of each find, and keep it together with the mushroom(s)? Then it will always match the actual habitat of the specific find.

Well, yes… but…

I’m sure the duff was most probably chosen at random. But the past few years when I could help out at the fair setup, I would try and make sure the duff was chosen to fit the most common habitat of the ’shroom.

I mean if they are going through the effort of gathering separate sources of duff for the display, you might as well use them. Or why not just have a random mix of duff for displays?

“If it is T. griseoviolaceum you should change the basket there, from pine duff to live oak duff.”

Although that is the logical thing to do, I kind of think the duff was chosen at random for decoration… At least that is how I think it has been at every fair I have been to.

This does look more like it…

I would say it does look more like T. griseoviolaceum. Someone should check, with some water on the cap, that it is viscid. Also the habitat should get checked, it should be in live oak, not pine. If it is T. griseoviolaceum you should change the basket there, from pine duff to live oak duff.

is this date right Alan?

Was the cap viscid?
By: Douglas Smith (douglas)

Did people check if the cap was viscid here? What was habitat here? The stipe is rather white here, and it would be good to see the gills. For T. atroviolaceum the cap is rather dry, slightly fibrous, and the gills are grey, the stipe a lighter grey.
