Taking into account the extreme variability of the species and the more redish cap, I think that Boletus luridus var. rubriceps fits quite well.

that’s why Singer described B. caucasicus.
if Boletus luridus what about Boletus luridus var. rubriceps?

“Are the pores really that pinkish or is this only in the picture?”, but I don’t see only pinkish there, the pink is scrambled with and/or vinaceous-red. Anyway, I think that the photos faithfull reproduce the colors.
Moreover, I see orangish/red or better orangish/vinaceous-red under the tubes, with some yellow closer to the margin; The photo with the reaction to cut is a bit blurred, but in the outer zone (on the right in the photo) I can see some red in the line separating the tubes from the flash (I’m used to call it “bataille line”), whereas that line is blue closer to the stem. But, to my experience, it is common that some specimens present a clear red line while in others this line is not so well defined.

What do you mean with that?

I cannot see the “pelteraui” line if you mean that.
What I can see is that the bottom of the tubes is pinkish red. That would point to Boletus comptus.

Gerhard, you said “My own experience with Southern European species tells me though that some mushrooms look indeed very different down there”. Even knowing this, why do you “ignore” the distinguished feature mentioned, the color of the flesh under the pores. Every other species you will propose, lack this feature.

Habitat: zone of calcareous rock without big trees; dominating species Quercus coccifera.

Gerhard, the link doesn’t show a very good picture (heavy blue cast), but I think there’s a slight blue cast in zaca’s pictures too, except the one where the tubes are peeled off.
Might be helpful to know the habitat.

Look at this one.

match quite well.

B. luridus I do not think, pore color is so out of way.
B. rubrosanguineus I know very well from alpine habitats in Austria and is not found at lower elevations, at least here. I cannot imagine that it does grow in atlantic mediterranean areas like Portugal. But who knows? There have been so many species described from down there. My own experience with Southern European species tells me though that some mushrooms look indeed very different down there. I considered (besides the mentioned key) also Lannoy & Estades and this find is in sectio Inquinantes or series Luridus but I couldn’t think of any other species right now. Maybe I’m just stuck. I also considered Boletus comptus but it is not.

luridus and rubrosanguineus look like better alternatives than permagnificus..shape of the stem, the colours

-if Boris Assyov isn’t completely mistaken:

a bit more intense than usual. However, according to boletales.com:
Boletus luridus differs from all the other European boletes on the account of the vinaceous, red or orange red flesh under the tubes when these are removed.”
