I took this big mushroom in the forest of Bouchet close to Annecy. Its scientific name is Boletus luridus.

It is edible, but this specie is toxic if eat raw or underdone because they contain toxic substance with fading over 70 degrees.

Cap : Immature specimens are downy and pale yellow. As the fruiting body matures, the cap, which expands to between 8 and 14 cm (exceptionally 20 cm) in diameter, becomes dull yellow-brown.
The yellow cap flesh turns blue-black if it is cut or bruised.

Tubes and Pores : Beneath the cap, yellow spore tubes terminate in tiny circular pores that are at first yellow but eventually turn orange-red.
When cut or bruised, the tubes and pores rapidly turn blue-black before fading to pale blue.

Stipe : 1.5 to 4 cm in diameter and 5 to 10 cm tall, the swollen stem turns dark blue when cut and then fades back to a light blue colour, as seen here. The flesh near the base of the stem is deep yellow with red tinges.
The surface of the stem is yellow, covered with a red mesh patterning everywhere except for the top of the stem, which remains yellow.

Habitat : Most commonly found under beech trees on calcareous soil, this species is also occasionally seen beneath oak trees and limes.

Season : July to late October.

Taz, Another nice speciman with great colors & perspective. Good use of your on camera flash? Great supporting note also. Someday I'll break down & buy an external flash but they aren't cheap so it's on the back-burner for now. I think the saying goes "when you control the light, you control the shot!"

Nueva muestra de tu talente para encontrar y capturar este tipo de imágenes.
Hermoso colorido, gran perspectiva y encuadre, junto con un atinado DOF y una completa nota.

New sample of your talente to find and to capture this type of images.
Beautiful colorful, great perspective and frame, along with an accurate DOF and one complete note.

I guess you had to bow down for this one, or lay on the ground. Very interesting and detailed shot you managed here. Perhaps I should start and look for myself after some mushrooms.

Thanks for posting.

Nice one Christian, good DOF and colour, a little over exposed on the leading edge lossing some detail but the rest is very good. have you tried a sheet of white paper stuch over the flash to calm the amount of light given off.
Notes spot on again.

tres beau bolet !
tu sais vrament bien comment prendre les chose....je fais reference a la mousse qui donne vraiment un charme a la photo.

Beau shoot ;)

Joli cadrage et une profondeur de champ bien maîtrisée et en plus le flash n'écrase pas trop les couleurs du bolet.
Bien vu Christian.

We are having a very good set of mushrooms around here lately, and this one would be perfect for a identification, is very descriptive.

Very good composition and very good colours, I can see that you have a little problem with exposure, you should use FEC (flash exposure compensation) if you have it in your camera because you 'killed' the front of this mushroom.

The lighting, color and DOF in this shot is excellent. Your note and image makes for a very powerful and informative post. Thanks for posting.

Anotheer one great specimen for the pan! It looks great Christian, I love the sharp focus edge, nice contrast with the background. I also love the texture of the underside. I got a few shots of these not so long ago, but I don't think they are anywhere near as good. Excellent work.

And the hits just keep on comming. Christian, nice one, love the texture underneath. Very informative note. A tad of overexposure on the front but not much. Thanx for sharing.

It amazes me that you keep finding more of these interesting plants. I think participating in TN pushes us on to areas we may never have been and thats a good thing. Very good shot Christian.

Hi Taz,
another good photo.
about culinary use, must be remembered that this specie is toxic if eat raw or underdone because it contains toxic substance with fading over 70 degrees.
Anyhow, I like it very much. For me it is the best Boletus in the kitchen (alike Boletus erythropus).
