Melanoleuca melaleuca is a species of mushroom in the Tricholomataceae family, and it is the type species of its genus Melanoleuca. It is difficult to distinguish from other related species firstly because it is variable, secondly because the taxonomic criteria are often based on characteristics which have later been found to be variable, and thirdly because there is much disagreement between authorities as to exactly how the species should be defined.
This description is taken from several references, which generally agree except on microscopic features.
Due partly to the confused taxonomic definitions, this mushroom is very difficult to identify with certainty. Various authorities imply that around M. melaleuca there is a complex of closely related species without clear dividing lines, and that the current analysis (which varies from one author to another) requires more clarification. Much of the taxonomic work on Melanoleuca has been done in Europe and the status of North American specimens is less certain. However a 2012 paper by Vizzini et al. proposes updated definitions based on DNA analysis and suggests that some progress on these issues is being made.
Both the species name melaleuca and the genus name Melanoleuca come from the same Ancient Greek words for black (μέλας - melas) and white (λευκόν - leukon). The species name was originated by the Swedish mycologist Persoon in his 1801 publication Synopsis Methodica Fungorum, as Agaricus melaleucus. This formed the basis for the genus name Melanoleuca which was invented by Narcisse Théophile Patouillard in 1897 as a variant of Melaleuca.
