appendiculatus has also been moved to genus Butyriboletus. This species is reported from western North America. I just read the description in BRB, and it does seem to be very close to B. brunneus.

Formerly, Boletus speciosus var. brunneus.

I usually only find this one early in the season, mid to late June. I think the recent spell of cool weather followed by hot weather has triggered some interesting fruitings of boletes.

Reminds me of the European boletus appendiculatus.
