I need to find this thing again…

I remember the spot and I did look for it last year and the year before, except that it wasn’t fruiting. When I do find it again, I will preserve a collection and run the DNA… At this time, I tend to side with Noah that it’s probably neither rubrobrunneus nor violatinctus.

I find a of these tannish/violaceus Tylos.

Sometimes I kinda think they’re “violatinctus”; most often “rubrobrunneus”. Not that this means one species is more generally common than the other. But, most times (aside from the dependable rubrobrunneus patch 60 feet from my house), I don’t feel confident one way or the other.

Oh yeah, Martin, I’ll be looking for these again. DNA sequencing is in order, too. :) I can get ITS and probably LSU, but according to Nuhn’s 2013 bolete paper you need a 3-gene core analysis (LSU, TEF1 and RPB1). Got any good contacts?

There is your ticket to fame. Collect this year and write a paper with Noah, Walt, Roy (of course), and I and you will be up there! The road is wide, step forward without fear!

It wouldn’t surprise me

if these are an undescribed species… They don’t really match my concept of Tylopilus violatinctus, (color, stature, staining, reticulation at apex are different), nor do they have the right colors/staining for Tylopilus rubrobrunneus.

These were growing on a road bank (bracketed by trees on both sides) under some bushes, so not bleached out by the sun. Thus, I think these are too pale for their age to be T. plumbeoviolaceus. I happened to find the latter in this park a few years back, growing just a quarter mile down the road (http://mushroomobserver.org/71282?q=1tyVa).

I remember the approximate location of this collection such that I can hopefully gather vouchered specimens and measure the spores to rule out look-alikes.

to see this discussion. I don’t think I have found T. violatinctus – always turns out to be T. plumbeoviolaceus. I see T. rubrobrunneus most years that I visit Shenandoah National Park, I don’t remember lilac. Your photos show a big bulb!

I’ll go with Tylopilus violatinctus. It is not a common species in my area.

Check out my other two posts, which I believe are the same mushroom:



All three were collected in the same park. I believe that 75191 and 137365 came from the same spot (though I have no way of confirming it) and 27199 was definitely collected elsewhere in Brendan Byrne. Note that you voted “I would call that” T. violatinctus for both 27199 and 75191. It’s time to make up your mind. :)

The clavate bulb is not significant in my opinion. The olivaceous stains are. The lilac tones on the stipe do leave some doubt in my mind.

Really, Walter?

To my knowledge T. rubrobrunneus doesn’t have a lilac, clavate-bulbous stipe that stains yellow-brown. These do — make sure to check out the pix.
