It’s ammonia that gives the green flash on cap; KOH stains the cap deep red.

Thanks for your tireless efforts here, Igor.

Damn I wish I’d put KOH on it to see that “green flash” they describe. I’ll check to see if there’s another this morning.

…this mushroom, the more I think it’s just a morpho-variant of Aur. innixus. The stipe of this species is usually textured with lines and ridges that mix in with the brown streakiness. The overall colors scheme of this collection, including the golden yellow pore surface, is consistent with innixus. I frequently find this taxon as solitary fruiting bodies, not as caespitose clusters… Always go with what you know – chances are you would be right! :-)
Sorry, Geoff, no leccinum for you, better luck next time! :-) You should have smelled this bolete — innixus has a very pungent odor, reminiscent of witch hazel. Maybe the dried material retains the odor.

the possibility of it being a Leccinum it’s a group I’ve never seen.
I wish I’d done a bit more before I threw it in the dryer. If I’ve learned anything from “Boletes” it’s that they’re never what you think.

We’ll get some wild idea from the DNA soon! :)

If the scabers are real and darkening in age, this could be a Leccinellum sp. The yellow pore surface is in line with the generic concept, though again the color in this collection is vivid yellow.

Any other information?

Do the pores or flesh stain/bruise any color? The leccinums that [I think] Igor is considering often get some pink bruising to the flesh, particularly by the stem. Was there any notable taste or odor? Was the cap sticky or slimy when damp? Was the flesh a pale yellow, a dark yellow, or something else?

Any [shiver] chemical tests? Any report on the weather and other conditions?

What trees did it grow with? Were there other specimens around? Any that might possibly have had a deeply crinkled cap (again, that might pair to some particular possibilities)? And which photo has the more accurate color, the one showing a yellowish cap or the one showing a reddish cap?

BTW, for Igor and Dave: I note that the photo was in centimeters, which makes this specimen around 2 inches long. It’s really small.

Oh, and Geoff? I am almost certainly no further along than you are in the whole ID thing. I’m just trying to ask all the right questions so those with actual knowledge can get a better take. The best news for me would be if I’ve missed any of those “right” questions because that would probably say the most! [grin]

Geoff, glandular dots…

may generally be rubbed into smears and/or make your finger become sticky. Scabers or other similar stipe ornamentation on a bolete are less apt to do this.

LOOKING AT piles of glandular dots. I am never going to get a handle on these things.

Hey, Geoff,

will this little park of yours ever run out of interesting boletes? :-)
This is not Suillus, as the stipe ornamentation doesn’t sport glandular dots and the pores are too bright yellow; the overall stature is not typical of that genus. The pore color suggest Aureoboletus (e.g., A. innixus), but the scruffy, scaber-like surface of the stipe instead points to Leccinoideae. If the latter theory holds up, maybe something related to H. subglabripes? Thanks for collecting!
