Observation 149714: Leccinum holopus var. americanum A.H. Sm. & Thiers

When: 2013-10-19

Collection location: Splashdam Pond, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

Damp mossy path lined by gray birch.

KOH grayish on cap, brown on pores/tubes.

Staining of cut context slowly pale reddish and eventually grayish. Patchy blue in the stipe base.

Stipe bases all with exterior greenish stain.

Spore print dull brown.

Although I have called this type, which I collect often in this same location, “holopus”, I can’t help but wonder about the possibility of “oxydabile” being a better name. The intensity of the reddish staining varies by collection, as does the cap color. Link below is for a collection made a year ago at the same location, which I believe represents the same species.

I suppose it’s possible that two similar species routinely inhabit this same area/habitat.
