Summary:
Also listed in Truffles etc. category. Features include 1) an irregular to top-shaped cap that is yellowish brown to reddish brown sometimes with yellowish or reddish tinges, 2) yellow flesh that turns blue when exposed, 3) yellowish tubes that are irregular and not vertically oriented, 4) angular pores that are yellow or tinged orange and turn blue when bruised, 5) a short stem that is yellow with reddish tinges and turns blue when bruised, and 6) growth under conifers, often partly buried. The taxon will likely be recombined as one or more species in a bolete genus. Var. flammeus, known from Idaho, grows on the ground under fir and has a pale golden cap with red blotches, bright red pores when young, and shorter spores 11-14 x 7-9 microns, (Bessette). Var. flammeus may occur elsewhere in the Pacific Northwest and other varieties are not well documented. Among false truffles in the Pacific Northwest, G. turbinatus is common, (Trappe(13)).

Microscopic:
spores (9.5)13.5-18 x 6.5-9.5 microns, elliptic to spindle-shaped, smooth, brown or golden, (Arora), spores (9.5)13.5-18(20) x (5.5)6.5-9.5 microns, elliptic to oblong or slightly oval, honey-colored, often with a fulvous tinge, "walls simple at first, later thickening and becoming 3-layered", "apex obtuse to acute and the wall there either continuous or showing a slight pore"; basidia mostly 4-spored but sometimes with 1, 2 or 3 spores, 35-38 x 9-14 microns, "rather voluminous, vesiculose-pedicellate to clavate", colorless or yellow in KOH, basidioles scattered, variable in size or shape, about 33 x 9 microns, mostly somewhat clavate, colorless; "pseudoparaphyses similar in size and shape to the basidioles but without protoplasmic content and hence not likely to produce spores"; cystidia rare but present in interior as well as pores, 35-60 x 9.5-17 microns, ventricose-mucronate to more often ventricose in middle and ampullaceous-pedicellate, often with a long thin neck, colorless, later either colorless or golden yellow to brownish, apex usually obtuse; clamp connections absent, (Smith)

Spore Deposit:
not obtainable (Arora)

Notes:
Gastroboletus turbinatus is found in WA, OR, and ID, and is apparently widely distributed in the western US and also found in MO, (Smith). It is also found in CA (Castellano). There are BC collections at the University of British Columbia.
