Truncocolumella is a genus of fungi in the family Suillaceae, of the order Boletales. ^[1] It was circumscribed by American mycologist Sanford Myron Zeller in 1939. ^[2]

The potato-like T. citrina is up to 7 cm broad. The spore mass is yellowish, darker in age. ^[3] One field guide lists T. citrina as edible. ^[4] David Arora cites one story that it may leave a licorice-like aftertaste that can persist for hours. ^[3]

To determine the odour of T. citrina, mature fruiting bodies were extracted in diethyl ether and analyzed by gas chromatography-mass spectroscopy (GC-MS). The two major odor compounds that were identified are hexanoic acid and phenylacetaldehyde. These compounds were not found on examination of immature fruiting bodies. ^[5]
