Trying to identify a Mushroom | Imleria Badia?!?

Now, go to the description.

I started to repeat these steps on the mushrooms that arrived in my hands. I put them on an absorbent paper foil and I took some shots. I ask my parents where did they find them, and they tell me the mushrooms were “in a prevalent chestnut trees wood” So I began to describe what I was seeing: I will indicate the parts as in the image below, distinguishing the cap, the stem and the hymenophore.

The cap was convex, well colored with brown on all the mushrooms. The smallest ones were 4-5 centimeters about in diameter, and the biggest ones were not more than 15 centimeters. The cuticle is the part you can see as a strong brown, but below you find the flesh: you can see it in the green-circled point of the image below.

The flesh, in this case, was white. Returning to the cuticle, it seems very "dry”.

The stem almost never was white, more brown, from light to dark brown, sometimes with an ocher-yellowish tone. It seemed that the colors have been applied in brush-strokes from the low stem to the cap, and without any reticle. In the youngest examples, the color became darker in the middle part of the external surface of the stem, becoming then brighter towards the cap or towards the point where the mushrooms were connected to the ground.

The Hymenophore, in this case, was constituted by pores and – made visible thanks to the next cut - tubes. This part we find below the cap of the mushrooms was the part more different from the classic Porcino mushrooms: the color you can view in the photo ranged between grey/greenish or dust white up to the yellow/greenish of the most mature specimens: colors that anyway were duller than the classic ones I find on a Porcino. But the most important point was that, if touched on the hymenophore, the color turned. This event is indicated as Turning, and, in this case, the color became dark green or dark blue in the pressed zones.

And then the cut or slice, the part we missed: slicing a mushroom means cutting the mushroom in more parts, usually starting with a vertical cut from the cap to the end of the stem. Using this method, we will obtain two halves ready to be described. In my case, I obtained confirmation that the cap flesh was white, that the hymenophore was constituted by tubes, and that the stem flesh seemed fibrous, as well as colored from white to brownish. The most featured observation has been the turning of the cap flesh to a slight blue color, precisely above the hymenophore's tubes. I tried to circle it in the image to make the concept more understandable.
