Notes: This could be fo. nigricans which I do not hold to be a valid form nevertheless since the only distinguishing feature seemingly is the strongly blackish cap color.

about the validity or the legitimacy of that forma. It’s just my opinion. I have seen such dark colored forms in rather mountaineous boggy spruce forests only and very rare, maybe thrice.
Not sure if anyone ever did DNA on this but DNA on all the edulis varieties or even species like betulicola or carpinaceus seems that they are all conspecific. I doubt it though.
I don’t recall having seen SO dark coloured edulis :-/
