Observation 181539: Leccinum holopus (Rostk.) Watling
When: 2014-10-03
No herbarium specimen

Notes: Pale cap color, older caps with distinct greenish tinge, pores bruising yellow/brown, cut flesh not staining, open area with small gray birch very small native spruce and intermittent wetness.

Lack of pink stain on cut context favors var. holopus.

Growing in same area, and probably the same species as obs 181540 .
Several collections made by my wife. I separated them by cap color and am basing three obses on this grouping. These are the very pale-capped ones.

KOH tested several hours after collection. KOH on cap surface scarlet orange fading to reddish-purple and ultimately to dull purplish brown. This is not even close to the BRB report that KOH causes a gray reaction on the cap of holopus. KOH on pores dark purple-brown. Photos showing KOH reaction taken outdoors the day after collection. Scarlet-orange reaction on cap not nearly as vivid as the previous evening. KOH on context slightly gray.
