Collection location: Seven Tubs Natural Area, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

Area dominated by hemlock. Birch present.

I \dried some of this, but the material is not in very good condition. I thought it interesting to see a Leccinum mushroom so early in the season, an old one to boot!

Based upon cap color and robustness…

I’d say subsect. Leccinum. But like you say, too old to interpret useful traits.

It’s so old, I cannot make it out to subsection.
If there were no other conifers but hemlock, then it’s a hardwood associate. Association with birch makes it subsect. Scabra only, but then it’s kind of early for these IMO. The ones from subsect. Leccinum have marginal flaps and can form mycorrhizae with both conifers and hardwoods (e.g., aspen). We usually have a flush of red-capped scaberstalks in the Pine Barrens late May into early June. I haven’t seen any this year, but then I didn’t really look for them…
