Observation 168052: Tylopilus balloui (Peck) Singer
When: 2014-06-16

Notes: Found in the Turkey Creek Unit of the Big Thicket National Preserve.
They pores appeared to have some pinkish hues and they bruised brown fairly quickly.
Spore print was weak but did seem to be a light reddish brown.
Spores ~ 7.9-9.9 X 3.0-4.0 microns and smooth.
While they appeared to be Tylopils-like, the taste seemed mild.
Thus far haven’t made a match….looking for assistance from MO’s eastern Bolete “experts”.
Possibly somewhat faded T. balloui?

Duely noted.

My suggestion is cosmetic, no problem seeing the spores.

through the microscope. I primarily am looking to make the spores(or whatever) as distinct as possible without regard for the background. Since it is an artificial environment to begin with, I feel it is more important to see structural detail rather than worry about trying to be true to the chemical medium I’m using.
I’ve been trying different things and I guess some of them are a little too much.

To set your camera’s white balance to ‘auto’ when shooting through a microscope. That will eliminate the colored background.

Martin, you are probably right

and I do think these are most likely T. balloui.
They are fairly common in the area and I had run across them before on this trip.
The Bessette Bolete book lists them as “sometimes bitter”.

Not an expert, but I have a couple of observations of T. ballouii:

The brown staining does not appear to be consistent (some of my obs. have and some do not). I have no spore photos to compare with yours. Taste not recorded, but Tylopilus, as you know, are normally very bitter.

But your photos do look very similar to T. ballouii.
