The monotypic genus Nematocenator was discovered as a fungus-related parasitic microsporidium that infects benthic nematodes at methane seeps on the Pacific Ocean floor (Sapir et al. 2014). This genus is a microsporidian which is a group of single-cell parasites somewhat related to fungi. This genus was introduced based on morphology and SSU rDNA sequence data from selected microsporidia and close relatives (Sapir et al. 2014). An editorial comment is given in Index Fungorum; “the generic name in this combination is not currently considered to apply to an organism within the fungal clade”. Bojko (2022), introduced a new microsporidia genus (Knowlespora) from pheasant shell mussels, which is sister to Nematocenator marisprofundi in neopereziida clade.
