Observation 144748: Leccinum Gray

When: 2013-08-17

Collection location: Grasslands National Park, Saskatchewan, Canada [Click for map]

49.1998° -107.6544° 854m

Who: Chris Hay (hayfield)

Specimen available

West Block GNP – 70 mile butte trail – aspen (Populus tremuloides) mini forest area (a more accessible West Block forest – a taste of the East Block larger areas)

Short and stout, “hamburger bun” type cap, black scales on stem, flesh and pore surface white when young, older specimens look brownish (if same species). Stains and bruises black but very very slowly… did not make detailed observations over time. Smell when dried very agreeable – mushroomy, but very sweet… causing me to salivate (though have never eaten wild boletes before).

Apparently a favorite for white-tailed deer and beetles, from my ~10 minutes of observations.

This specimen was growing among ground juniper, without aspen right on top though within a few meters…

Habitat description:
Forest is between two slopes, so soil is grey shaley stuff and often looks very disturbed (washed away from water flow). The vegetation is of only one tree species: aspen (Populus tremuloides). Along the ground where there are plants they are mostly ground juniper (Juniperus horizontalis), occasional small shrubs like snowberry (Symphoricarpos) or rose (Rosa), and sometimes a few mixed-grass prairie herbaceous species, as would be found in most of the non-forested surrounding area (eg. Pussy toes Antennaria sp., Yarrow Achillea millefolium, Bastard toadflax Comandra umbellata…)

Species Lists


three young ones growing together (herbarium specimen 1.5 of these)
top view – note dark bruising on caps
A deer was chewing this one – I saw it with the cap in its mouth, but it got scared off before I could get a pic. I went to where it was and found this. I assume it’s an older, larger specimen of the same species (seemed fairly common in about this 50m diameter if not wider area).
another large specimen in near area – assuming same species
another large specimen in near area – assuming same species
