T. citrina | |
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]
