Observation 45164: Australopilus palumanus (Wolfe & Bougher) Halling & Fechner

Notes:
Wolfe & Bougher use the presence or absence of a raised reticulum to distinguish 2 groups of taxa in Tylopilus subgen. Roseoscabra (the T. chromapes group). While such a distinction might have been artificially useful at the time, it is not clear if the feature is really diagnostic – I have seen T. chromapes with and without a reticulum in the same gaggle of basidiomes.
Tylopilus queenslandianus would possess pseudocystidia, and T. palumanus would not.
Herbarium specimens in BRI & NY (REH9275).

if you look here: http://redgum.nybg.org/boletineae/chromapes.php, you can see how the molecular phylogenetics supports recognition of Australopilus.

is this…
