Compare to Cyanoboletus cyaneitinctus f. reticulatus (rare) (source: Bolete Filter) OR Boletus subvolutipies

Growing alone along a garden retaining wall along mixed oak/hickory woodland edge partially shaded by post in a partially shaded clearing close to paved road.

• Short 6cm tall. Small bit of Hypomyces on hymenium and stipe apex.
• Cap: convex to flattening; orange, yellow, and red; surface subtomentose.
• Flesh: quickly bruising blue where cut, later cap flesh turning brown or dull tan. Stipe flesh turning blue quickly with notes of red and yellow with blue, later turning to yellow, red, and white.
• Hymenium: vibrant orange; flashing green then quickly turning blue where bruised. Pores in a maze-like pattern.
• Stipe: red reticulation turning blue to black where handled. Orange, yellow, and red colors. Base bulbus with short (2cm) taproot. Reticulatus a turn to longitudinal striations halfway down the stipe from the apex.
• Smell: indistinct to faint.
• Taste: faintly bitter.
• KOH: pileipellis: quickly dark red; hymenium: orange-red; stipe: bright orange-red.
• Ammonia: pileipellis: yellow with light yellow margin; hymenium: flashing olive changing to buff-yellow with yellow margin; stipe: yellow.
• Iron Salts: pileipellis: black; hymenium: black; stipe: flashing blue, then gray

Growing under Red oak, ash and American hophornbeam trees. Cap orangish-brown and somewhat velvet, bruising dark blue when handled. Pores orange closer to stipe and turning more yellow closer to margin, bruising dark blue. Stipe yellow near apex and fading to red at base with red reticulation about halfway down. Base of stem crimson red and somewhat velvet like. Context of whole mushroom quickly bruising dark blue when cut. On cap: KOH red, Ammonia slightly orange, and FeSO4 dark gray. KOH orange on cap inner flesh. Spores brown in KOH.

Not sure on the ID, the netting looks much darker red and distinct but this was the closest i could get to on bolete filter. Unfortunately I didn’t think to see if the mushroom bruised blue at the time!

Growing below mostly pine (some hardwoods) in a wooded area in a public park in Floyd County, GA.

Flesh yellow. Pores red-orange. Cap is a velvety reddish-brown. All parts stain when cut. Flavor is mild.

Chemical analysis:
Iron salts-->Gray on cap. Changes/erases blue (stained) areas of flesh and pores back to yellow.
KOH-->Dark red to black on cap. Peach on flesh and pores.
Ammonia-->Orange-yellow on cap.

Field notes: Townsend WMA, Murff Tract not far from the Altamaha River, xeric sandy soil, not under any trees but some small pines were maybe 5-10 meters away.

Field notes: 3 Boletes A. Biggest one 7 cm wide and 5 cm tall, smallest 5 cm wide 2.5 cm tall. Cap whitish with some brown, pores off white brown stain. Stalk brown at base maybe scabers above brown and depressed at top. Stalk expanded at base brown stain inside. Typical smell pleasant taste.

I sent all these images and info to Dr Alan Bessette who kindly looked at them and made the determination, with my thanks. This is a ridiculous range extension and i wonder if it might be a cryptic species? I will go back neat year and try to refind some for collection and examination.
@ ksanderson you have a lot of experience with this species I would love your thoughts if you are willing.
