Growing on the ground in mixed woods.
Cap was 7.6 cm across and somewhat velvety.
Pores did bruise brown.
Weak spore print was a light brown.
Spores were ~ 9.0-12.2 X 4.1-5.2 microns, smooth and mostly a stretched ovoid.
KOH on cap was alight reddish.
KOH on the flesh was initially yellowish.
White flesh was mild tasting and had a soft texture(marshmallowy).

I wonder

if the spore shape couldn’t fit the american version of Gyroporus castaneus after all. How many others have shown micro shots of the spores? I’m not sure that it’s the same as the european castaneus…

That’s interesting Dave,

While the spore size and stem doesn’t really match Austroboletus gracilis, I can convince myself that I can see some pits when one goes to max. size on my spore photo, especially the ones on the lower part.

Except for the short thickish stipe…

this reminds me of Austroboletus gracilis; tubes depressed near the stipe, bruising brown.

Mushroom Expert says the spores of A. gracilis are “pitted.” I can’t really tell what exactly this means from the spore photo seen at Mushroom Expert.

sometimes G. castaneus looks clunky and dark, masquerading itself as something it’s not, but its pore surface never stains brown. :)

It does have the G. castaneus look

but beside the spore problem, the flesh was very spongy and the chemical reactions were off. A good example of problems with just a photo for an ID.

It looks like Gyroporus castaneus, but the spores are a little too slim
