Greek phaios ‘dark, blackish gray’ + Greek diskos ‘quoit, disc’. For the color of the “disc”, i.e. the flattened plant body (see Spegazzini’s description of Echinocactus pygmaeus in Anales Mus. Nac. Buenos Aires (ser. 3), 4: 497-498. 1905), which distinguishes the taxon from Echinocactus pygmaeus var. pygmaeus (= Frailea pygmaea).
