kamˀatu - truffle (CAD K 120, AHw. 432)

J.-M. Durand suggests that the word designates not the truffle, but a different type of mushroom (Durand 1997:312). According to H. Reculeau it should be a representative of terfezia family. For the etymology, see the discussion in Kogan 2012a:257f.

PS
*kamˀ-at- - a kind of mushroom (Kogan 2011: 202)
