Growing alone in mixed hardwood/pine forest. No apparent association with wood.
Cap, ca 2 inches diameter; light tan with yellow ochre cast.
Pore surface white/translucent and darkening slightly; bruising brown.
Stipe white, showing a hint of reticulation particularly towards the apex.
Spore print, white.
Spores. Smooth, ca. 8-10µ x 2-3µ
Identification initially suggested by Davide Puddu
Growing under oaks in suburban lawn alongside B. luridellus. Dull brown cap with a faint suggestion of red in the cap’s Center. No staining. Inrolled margins. Dull yellow context that gradually turns a marbled gray-brown. Basal mycelium is white. Odor is mild, inconspicuous. Flavor is mild, with a hint of pepperiness that I may be imagining.

Dark (almost black, with maybe a faint suggestion of violet) pitted cap. Prominently reticulate stipe with violet undertones. No staining. Odor and taste are mild to pleasant.
Whatever it is, it’s keying out in BENA to B. separans.

Growing solo under a suburban live oak. If this southern separans-like bolete is, in fact, distinct from the northern separans, as postulated by Igor Safonov, collections like this one suggest that distinguishing between the two on the basis of morphology is gonna be tough.

Either separans or its southern double.

Dark burgundy caps that, oddly, lack the dimples I’m used to seeing. Also appear to have sterile (and occasionally beveled) margins. Beautiful reticulum. Growing under oaks.

Tylopilus pseudovariobrunneus I. Safonov & Kudzma nom. prov.
Unsure of Id.
Found growing solitary on pine straw near pine.
Smells fresh. About the size of a human pinky. Very ornate stipe.
