He included within it most species of fungi that were gelatinous, dividing it into the genera Agyrium, Dacrymyces, Exidia, Hymenella, Naematelia, and Tremella.

For Patouillard, the Tremellaceae was limited to genera and species in which the basidia were "tremelloid" (globose to ellipsoid with vertical or diagonal septa), whether or not the fruit bodies were gelatinous.

Patouillard's revised Tremellaceae included the genera Clavariopsis (= Holtermannia), Ditangium, Exidia, Guepinia, Heterochaete, Hyaloria, Protomerulius, Sebacina, Sirobasidium, Tremella, and Tremellodon (= Pseudohydnum).

[5] The next major revision was in 1984, when Robert Bandoni used transmission electron microscopy to investigate the ultrastructure of the septal pore apparatus in species of the Tremellaceae.

Bandoni referred the latter group to the Auriculariaceae, restricting the Tremellaceae to the genera Holtermannia, Tremella, and Trimorphomyces.
