A number of boletes stain blue, including some very edible species.
In general, the combination of blue staining and red stem or pores is
a danger signal.  Some boletes with these characteristics can be
violent pukers.  You may not die, but you may wish you had. :)

I don't see the poisonous species as resembling edulis much.  Boletes
are a pretty safe genus to browse, as long as you use reasonable
