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.

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.
