Observation 103977: Boletus pallidoroseus Both
When: 2012-08-05
No herbarium specimen

Notes: A single specimen growing under old oaks in grass.

Overall heigh = 13.5 cm; Cap diameter = 9.5 cm; Stipe thickness at apex = 4 cm, tapering down to 3 cm.

I have decided to place it in the bicolor group. Obviously, it’s not B. bicolor because it smells like chicken/beef soup. Yes, I know, Bill or Noah would probably say it’s B. sensibilis just on the basis of this characteristic, but… Many of us have stumbled into B. bicolor (just happened at the NEMF, too, and we dubbed it B. “pseudobicolor”) on the Eastern seaboard that smelled like chicken bullion and gave a green-blue flash with ammonia on cap. This one doesn’t do that (KOH and ammonia readily stain the pileipellis rusty yellow), but the smell is rather strong. So there could be at least two different taxons that share the aroma with B. sensibilis.

Notice the flesh color — almost white in the cap, getting progressively yellow toward the base of the stipe, where it’s lemon yellow. No bluing on the surface of the stipe, but the pore surface does bruise blue. Not much bluing on the context either.

Species Lists



Bluing of the injured pore surface is instantaneous, reaching maximum intensity in 2-3 seconds; the color eventually resolves to brown-gray (reddish-brown for a light brushing against the pore surface)
Ammonia on cap contex (left yellow) = pale blue; 3% KOH on cap contex = pinkish orange

that with a fresh cap that has not yet faded, the smell (which to me is intense in this species like you describe more meat than curry) and the chemical tests, how is this not a possibility?

compare this with Boletus pallidoroseus
