Recognized by sight: The habit, the hymenophore color, and apparent bruising reactions, point to a Tylopilus in the balloui consortium. They have bean-shaped spores.

Tylopilus balloui consortium -

In Australia, there is only one species described that I know of – and it was put erroneously in RubinoboletusR. phaseolisporus – by Watling. The balloui consortium is very speciose in Australia, easily recognized by their bean-shaped spores. Colors range from white, yellow, orange, pink, red, olive, gray to gray brown. The hymenophore varies from regularly tubulose to favoloid. I have posted several Obs. in MO showing the color variation. All have been named T. balloui knowing full well they are NOT that species.

Two separate molecular analyses (one by T. Osmundson, one by M. Nuhn) place the “ballouioids” in Tylopilus.


Richard. The fungi was in an open area well clear of surface roots and on a slight bank where the forest road had been prepared. It for all reasons in my view was Phlebopus marginatus till you mentioned Buchwaldoboletus.”! which I was unfamiliar with. This fungi is reasonably common in single finds in this area. This specimen was growing in the substrate free of roots and easily removed from its habitat.

the pore surface is throwing me off…
the color is usually yellow in Buchwaldoboletus species.

what trees were nearby?
did they appear at the base of tree or look like they may have been attached to roots?


I have found larger sole specimens in this locale before and presumed?? the ID.
Maybe it is “Buchwaldoboletus.”! Is there a visual ID difference please. What are the scoped spore images like? Are they different enough for me to make an ID. Thanks for your really quick remarks on my finds. Chow, kk

almost reminds me of Buchwaldoboletus.
