Description:
Registration number: IF 551553
Distribution: Dunnellon, Florida, USA
Ectomycorrhiza: Presumed with oaks.
Diagnosis: Pileus: 6–16 cm wide, pulvinate and distinctly folded and lobed margin with a narrow band of sterile tissue, strongly incurved, undulating, surface dry, somewhat velvety, with irregular pits and depressions, sometimes cracked in age, color variable, brick-red or rosy red over a yellow ground color, becoming yellow-orange or mustard-yellow with dull pinkish or rosy tones within the folds, with burgundy-red or brownish red splashes on portions of mature specimens, slowly bruising greenish blue to grayish blue, quickly staining pale gray with NH4OH. Context: pale yellow to yellow, becoming darker yellow when exposed, sometimes slowly staining grayish blue odor and taste not distinctive. Hymenophore: yellow, becoming olive-yellow to olive-brown in age, rapidly staining greenish blue to grayish blue when bruised, dull brownish red around marginal folds, conspicuously depressed at the stalk in age tubes 4–13 mm deep. Stipe: strongly tapered downward, ventriose or with a pinched base, solid surface scurfy-punctate, sometimes smooth at the apex, often longitudinally striate, dull burgundy-red to brownish red over a yellow ground color, darker at the base, typically yellow at the apex, staining greenish blue to grayish blue when bruised or handled, often with pale yellow basal mycelium context concolorous with and staining like the cap flesh, usually orange-yellow to orange near the base. Spore deposit: olive-brown. Microscopic features: spores 11–17 × 3–5 μm, subellipsoid to subfusoid, smooth, hyaline to pale brownish yellow.
