A genus of amorphous hymenomycetous fungi consisting of tremulous gelatinous substance, typical of the N.O. Tremellaceæ or Tremellineæ, most species of which grow on decayed wood, but a few on the ground.
Tremella auricula is known as Earth-jelly, T. albida as Fairy Bullet. T. mesenterica is conspicuous in dead hedges in winter from its orange tint.
