 Hosts include members of the corticioid fungi, polypores, and Dacrymycetales in the Basidiomycota and species of "Diaporthe", other Sordariomycetes, and lichens in the Ascomycota.Some "Tremella" species parasitize the fruit bodies of their hosts (sometimes incorporating host hyphae), others parasitize the mycelium within the wood.As a group, "Tremella" species occur worldwide, though individual species may have a more restricted distribution.
