The blue staining of your fungus sounds somehow disquieting for a
Some species have bright bleu-green colour at the stipe base but bleu
staining is unknown to me in the genus (usually outer parts don't
clearly stain when bruised and flesh turns pink, red, violet, grey,
We have a very good monograph of Leccinum in Europe for a few months
(Lannoy & Estades). I can send you the reference to get it if you are
interested. The book encloses plentyfull of very good colour plates.
The only Leccinum with pure white basidiome and prominent blue (already
on the unbruised specimens, at the base of the stipe) colour is
L.cyaneobasileucum, so far recorded only from France and rather rare.
A more complete description and good illustrations would be usefull to
trace the identity of your specimen. Dis you notice some chemical
reactions (they are very useful in the genus)...
Hope this helps.
