I've noticed that the boletes with red colors and blue stain are often the first to pop up around here.. before the good ones are about. Except for Boletus badius which is also early and blue staining, however no red color on it at all.
In my books, any sign of red on any part of a bolete is a no-eatum.
I've had several blue staining types that are delicious, however.
Butter yellow flesh, and when dried they smell like honey... just like B. edulis.
