When: 2013-07-28

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

49.2007° -106.7702° 965m

Who: Chris Hay (hayfield)

Specimen available

East Block GNP, in NW “Story Lull” aspen forest area

Growing from ground in thick leafy litter near aspen trunk
Very common/ abundant in near vicinity (at least 10 FBs within a 5 meter radius area)
Caps bright yellow, very very sticky (even stringy when touch with finger and pull away), yellow skin on cap was peelable

Surrounding vegetation:
Aspen (Populus tremuloides)
Violets (Viola sp. – probably Viola canadensis)
Rose (Rosa sp.)
Dwarf Raspberry (Rubus pubescens)
Sedges (Carex sp.)
also other Russula species common in area

So pretty typical aspen forest… the only trees were aspen (apparently there are maple (Acer negundo) in the area, but I didn’t find any where I looked).

I will attempt to key out to species in the future… meanwhile any ideas are welcome.
