but this is not a Xerocomellus, this is a Boletellus.

according to http://www.czechmycology.org/_cm/CM60104F.pdf
Xerocomellus spores can be longitudinally striate.

certainly point to Boletellus. The species imaged is likely one Nigel and I have provisionally named B. sinapipes because of the mustard-colored tomentum at the stipe base. Also, K. Syme and R. Robinson have noted it for some time now in southwestern Western Australia. Thanks for the spore pics, Ian.

Roy H and fellow MO’s

Finally got around to doing some micrographs. The quality is acceptable I hope?. All three images were taken of the same spore specimen which was taken from the outer edge of the pileus and included some of the underside of the cap.
I am not sure why I ended up with different temperature colours?. I used Melzer’s reagent for the test. (x100)

but we’d need to look at spores to be sure.
