Genus Tremella “one of the original genera created by Linnaeus in his Species Plantarum of 1753.... Linnaeus placed Tremella in the algae, including within it a variety of gelatinous growths, including seaweeds, cyanobacteria, and myxomycetes, as well as fungi” (Tremella; Wikipedia, January 2019). Revised by Persoon in 1794 and 1801, “repositioning the genus within the fungi.”
