Genea harknessii, commonly known as the dark geode truffle,[1] is a species of fungus in the genus Genea. The species was described by Helen Gilkey in 1916.[2]
The mature fruit is up to 2.5 centimetres (1 in) across.[1] It has a convoluted, coral-like appearance. The exterior is dark brown (to nearly black) with a hollow interior, the surfaced of which is dark brownish.[1] The sterile flesh between the dark interior and exterior 'skin' is white to grayish.[1]
G. harknessii grows underground in forests, especially white oak forests, but also coniferous woods.[3] Although pigs hunt it, its edibility to humans is unknown.[1]
