Observation 218361: Cyanoboletus pulverulentus (Opat.) Gelardi, Vizzini & Simonini
When: 2015-10-08
No herbarium specimen

Notes: Solitary specimen growing in a spot where I haven’t seen it in the past. (There’a a dependable patch in another area of my property.) Near a very old buried stump, about 10 feet from a an old Shagbark Hickory, which is the only tree that seems to make sense as a mycorrhizal partner. Maple also present, aspen across a paved road. The other pulverulentus spot on my property also features Shagbark Hickory (and apple).

KOH orange on context, muddy orange on pores/tubes, darkens slightly on cap. Ammonia orange on context and pores.

Stipe apex with ribs forming a partial reticulatum.

I think it’s remarkable that such a typical summer bolete would fruit in mid-October. Gorgeous specimen, by the way.
