Incredible bee aggregation! They were super active. Mostly males flying around right above the ground. Only a few females out and I didn't see any with pollen. Nests mostly covered with leaf litter. Hundreds of bees at least, in an area about 10 by 3 meters right by the stream.
Interesting shape😂
The blue bruising reaction of the pores is at this link:

The blue staining of the cut flesh can be seen here:

No visible spore print; specimen probably too old. [CORRECTION: Spore print faintly yellow overnight.]
Spore microscopy will be performed later and this observation will be updated.
Growing under Populus tremuloides and Abies concolor.
Pores and all parts of the flesh stain blue with bruising/cutting in 15-30 seconds.
A portion of the dried specimen will be sent to David Arora for sequencing, and the remainder will be put in the Gilbertson Herbarium at the University of Arizona.
At the time of creation, this was the most westerly and southerly observation in North America on Mushroom Observer, and according to Arora, it may be the first collection west of the Mississippi River.
ADDENDUM 9-6-2015: Spore measurements were performed. Description: 7.8 [8.0; 10.3] 10.8 × 4.9 [5.1; 6.1] 6.2 µm; Q = 1.38 [1.46; 1.77] 1.90; N = 60; C = 95%; Me = 8.9 × 5.5 µm; Qe = 1.61
Found growing on open grass. Isolated.
Exsudoporus ruber (M. Zang) Gelardi, Biketova and Vizzini, formerly Boletus kermesinus, growing in spruce forest in 3880m, supposedly edible after cooking.
Found in Carter County, Southern Oklahoma. Near oak tree debris, and small elm trees.
Under hemlock, although diverse conifers and hardwoods, including pine and red oak, nearby
Keys to Boletus discolor in North American Boletes
Olive spore print
In sandy, clay soil attached to sandstone rock
Found growing under white birch. Flesh yellow quickly bruising blue. Stalk reticulation from bottom to top, bruising black when handled. Pores bruising red immediately then quickly fading to black. KOH turns the cap a darker brown/vinaceous brown.
Iron salts didn’t do much so I swabbed some water on and it appeared to do the same as the iron salts so negative there I guess.

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.
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!
Mixed hardwood/Tsuga forest. Stained blue rapidly when damaged.
Found growing from soil in garden bed mulch. Nearby trees are hibiscus, crape myrtle, and cherry Laurel. Color changed fast when cut.
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.
ID: JSL 1
It’s actually A Boletus Mahoganicoloroides

STAINING:
– pileus: see penultimate photo

blue bruising on pores
Smells sweet and definitely tastes sweet, blues immediately, yellow mycelium
???
Boletus vermiculosus - yellowish cap and wormy flesh
Neoboletus luridiformis - reddish reticulation
Boletus subvelutipes - dense red floccules
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.
In predominantly oak-hickory woods, near several White Oaks.
Taste mild, not bitter.
Context in young and old specimens white, but with pale lemon yellow when scraped.
Under primarily Bur Oaks (Quercus macrocarpa), perhaps some Red Oaks (section Lobatae) too.
Sweet, no bitter
Found near hardwoods.
