Second pic seen in link

posted here shows a specimen of B. pallidus with a longish, thin, curved stalk. Although not typical of the ones I find, I do not view this as an anomaly. Watery blue (light blue without any greenish tints) on the pores is what I’d expect for B. pallidus. Difficult to determine from the pics seen here (24570), but I believe there were not any scabers on the stalks. Peachy tint on cap does seem a bit unusual for B. pallidus… but I think there have been a few others posted this past summer which show this trait.


In the future I hope to post higher resolution pics… Had got into the practice of using lower res cuz it’s easier to post those shots at various internet locations. Seems to not be a problem at MO.

Usually I turn off the flash

because the natural color gets altered, although the second pic looks like the flash may have fired. The stalk here is quite long for B. pallidus, which also causes this one to look like a Leccinum. Watery blue bruising on the pores, and the KOH reaction rule out L. holopus.

Looks like the camera flash bleached out the images, so the mushroom looks more like Leccinum sp. Did the pore surface stain green-blue when bruised (there is an inkling of that at the edge in the second picture)? The overall appearance is more Leccinum-like, too. Could this be L. holopus?
