Observation 20552: Boletellus dissiliens (Corner) Pegler & Young

This specimen was found in close proximity to Image 20551. I believe it to be an immature growth but similar to 20551. The cap has similar growth appearance and the size is comparable to the mature specimen shown in 20551

Veil attachment . . .

That’s right J.H., the cap margin extends to clasp the stipe (but is not part of it) and covers the hymenophore when young. With expansion and maturity, this tissue does not “keep up” and ends up as the ragged flaps that hang from the cap edge.


Thanks Roy. I was really confused by the way the veil travelled down the stipe. I could not find anything in my reference even mentioning it.

Nice picture

the veil is attached to the cap instead of the stalk light agaricus species for example..right?

It happens sometimes in the developmental process . . . Look at the immature B. emodensis (Image 41632) I posted a few days ago.

what is up with that odd partial veil that extends down the stipe?

Ian: this is VERY close to what we found on Fraser Island in February. Cap flesh yellow and cyanescent. Any scaliness is quite flattened when young, and there is no hint of red (rather subtle pinkish buff). No bluing in stipe (rather it stains a brownish orange). If your did these things, I would wager it is Boletellus dissiliens Corner. Go to: www.nybg.org/bsci/res/hall/boletes/ and click on the sect. Boletellus link. To be absolutely certain of my ID from Fraser, I await arrival in NY of my vouchers.
