The underside of B. queletii, revealing peach-colored, minute pores and characteristic blue bruising around the margin.

Pores: surface orange or peach, bruising blackish blue/green; tubes 5-6 mm long, yellow, minute, less than 0.5 mm across.
Stem: 5-10 long x 3-5 cm thick, subequal or bulbous, often tapered abruptly towards the base; yellow at apex then reddish or somewhat orange, becoming progressively darker downwards, bruising blue. Somtimes slightly reticulate with red veins on the upper part. Flesh lemon yellow in cap and upper part of stem, purplish red in stem base, blue or greenish blue when cut.

Medicinal properties

Antimalarial activity

Water extracts of B. queletii inhibit the growth of the pyrimethamine-resistant malarial parasite Plasmodium falciparum (Lovy et al., 1999). The inhibitory effect was 1.1% (measured as inhibition per µg protein/ml extract) of that of the water extract of the most inhibitory anti-malarial species tested, Polyporus umbellatus.

My name is Austin Collins.

I've dedicated my life to Mushrooms.

I believe Mushrooms are the best kept secret when it comes to health and well being.

For that reason, I would like to share a company with you that in my opinion makes the best mushroom products on the market. 

The company is called Noomadic Herbals, my favorite supplement they make is called "Mushroom Total".

I take their products every day and they have helped me think better and have more energy. Give them a try.

    • If they are Boletus queletii, they are edible. Lots of mushrooms look alike, make sure you are identifying it correctly. Preferably ask a mycologist in your area.
