Porpolomopsis lewelliniae, commonly known as the mauve splitting wax-cap, is a gilled fungus of the waxcap family found in wet forests of eastern Australia and New Zealand. The small mauve- or lilac-coloured mushrooms are fairly common and appear in moss or leaf litter on the forest floor in autumn, and are biotrophic. The key distinguishing feature is the splitting of the cap dividing down the middle of the individual gills.
It was initially described as Hygrophorus lewelliniae by Hungarian mycologist Károly Kalchbrenner in 1882, and later as Hygrocybe lewelliniae by Brittlebank in 1940, before being placed in the genus Humidicutis by Australian mycologist Tony Young in 1997. A molecular phylogenetics study found it to be more closely related to the type species of the genus Porpolomopsis, Porpolomopsis calyptriformis so it was transferred to Porpolomopsis. The original holotype specimen had been collected on 14 June 1880 in the vicinity of Western Port in Victoria by a Miss M.R. Lewellin and sent by Ferdinand von Mueller to Kalchbrenner in Budapest. It was likely destroyed in the First World War, although a watercolour of it by the collector survives and is located in the National Herbarium of Victoria. It has been compared with collections made by E. J. H. Corner of a Mycena rimosacuta in Borneo and found to be the same species. It may be that Humidicutis mavis is merely a white-coloured form of this species.
