Returned to the spot for further analysis.
To my despair, the specimen vanished. I strongly suspect fellow observers :)
Next year, maybe.

No, this specimen and other ‘real’ M. procera in its neighborhood were neither too dry nor too wet. It must be a variety of some sort.

it to be so dark due to low temperatures, fog or soaking. But it does not look soaked.

They are a lot of M. procera around in this part of the forest at this time of the year. This specimen was very distinct from others, for its dark greyish tones on cap and quite dark stipe. No idea if is still M. procera, but it is different from the usual ones.

It is too dark and somber for procera IMO.

The scales on the stipe are almost sooty as is the surface of the cap in more greyish tones. It would help to see if the mushroom turns to olive-greenish on bruising or when getting old especially on the cap.
Of course procera cannot be ruled out fully.
Another thing to observe would be if the rind of the stem turns pinkish-reddish when you scratch it with the fingernail.
