No, not truly reticulate

just very thickly and densely floccose. Which would point to L. melaneum too. But there are some rare ones with this feature too.

Okay, scanning through Lannoy and Estades monography without knowing flesh change etc. are possible candidates:

Leccinum roseofractum (which should turn slowly pinkish in context)
Leccinum melaneum (which today is considered a mere variety of scabrum)
Leccinum murinaceum (don’t know if this is a good species)
Leccinum fuscoalbum (don’t know if this is a good species)
Leccinum nigellum (which is almost pseudoreticulate)
Leccinum variicolor (but that usually has sprinkled cap color and its varieties would grow in sphagnum mosses in bogs and very wet locations)

There are others but with them the cap isn’t that dark (USUALLY though)

There is

another feature: the stem is reticulated, isn’t it?

You need the two monographs

from Engel and Lannoy and Estades for determining Leccinum in Europe. Even then some finds are impossible to rightly ID imo. I love Boletales but Leccinum is a near-death-experience :D

Best would be to just name it Leccinum sp.

in doubt too, there are many similar Leccinum, and unfortunately I didn’t brought it or cutted it. The feature that I noticed was the large stipe compared to the cap.
So, we must call it as the more look-alike not to mislead the viewer.

I do not believe

this is scabrum. Cap color would point to melaneum or roseofractum. There are so many options. But we will never know. In Leccinum it is of importance to cut the fruitbody and watch the decoloration. For example, in Leccinum pulchrum it really fast turns strongly pink whereas in true Leccinum scabrum it remains unchanged.
