Tremella normandinae is a species of lichenicolous (lichen-dwelling) fungus in the family Tremellaceae.

[1] The species was described as new to science based on material collected in Hawaii.

The holotype specimen is preserved in the Botanische Staatssammlung München (herbarium code M) under accession number M 4837.

The only known collection comes from the lichen Normandina pulchella growing on dead Acacia koa trees in sunny exposures in Hawaii.

[2] Infection by the fungus results in the formation of pale galls on the host lichen.
