It produces hyaline, pustular, gelatinous basidiocarps (fruit bodies) and is parasitic on pyrenomycetous fungi (Diaporthe species) on dead herbaceous stems and wood.

In 1970, examination of Berkeley's original collections by English mycologist Derek Reid showed, however, that Tremella tubercularia is a gelatinous ascomycete, now known as Ascocoryne albida.

[1] It is not clear if the two species are distinct, though Scandinavian collections identified as T. indecorata are grey to date brown when mature and have larger spores (8.5 to 15 by 8 to 12.5 μm).

[6] Outside Europe, Chen considered North American collections as "closely related" to but possibly not conspecific with Tremella globispora.

[7] Chen also considered Tremella bambusina, described from the Philippines, as a probable synonym, differing only in its brownish orange colour.
