No specimen available

Earliest that I can remember ever finding a leccinum.

In the shade of a large rock, open area, sweet birch tree closest (about 15 feet away). Cut mushroom initially white throughout. Context in upper stipe staining fairly slowly pinkish. The photo showing this was taken about 3 minutes after picking/slicing. After a few hours the pinkish context changed to a light bluish-gray. Specimen, about 2 inches long, cap (if flattened/expanded) maybe 1.5 inch.

KOH on cap surface brownish. KOH on stipe gray. Not much KOH reaction on context. FeSO4 on pores and context slowly blackish. I’m not certain I’m using these bluish FeSO4 crystals correctly. I tried two things… rubbing the crystals onto the mushroom which seemed to produce little change, then adding a little water after which I got the blackening.
