A solitary specimen in suburban residential lawn. Nearest tree associates 30' away and include Oak, Maple, Sweet Gum, and Redbud. Boletes remain my nemesis, and while trying to key this one out and using some other resources I found contradictions galore when I narrowed the ID down to either T. badius or T. ferrugineus. Of course, I may not be correct with either identification; however, at this point I am leaning toward the latter based on the suburban, rather than woodland, habitat. Cap (measured across the top) 12 cm., small in-rolled sterile margin. Stipe: 7 cm. X 2.5 cm. (see image #1340), purplish net reticulation on stipe and some white reticulation at the apex, white mycelium at base. Tubes: 6 mm. Pores: angular, 2/mm. Pore surface: originally white, gradually developing pinkish-tan overtones, bruising light brown. Chemical reactions can be seen in collage images. Spore print pending.
