Per the 2015 Annual Checklist of the Catalog of Life, Myxomycetes are a class of Mycetozoa, which is a phylum of kingdom Protozoa. See http://www.catalogueoflife.org/col/browse/tree/id/22040749.
It appears that the Catalog of Life division is more current.
Who cares what the name of the Class is when the MO observation cannot be identified any closer. MO should aim for MO observations that would be reliably identified, supported by herbarium specimens, and well documented by MO images. Only then you can decide on “the best name” for such a Mushroom Observer observation. Slime molds (and any other organisms in that matter) do not care how they are called.
“In the class Myxomycetes 3 subclasses, 6 orders, 15 families, and 64 genera
have been recognized and, according to Lado (2005–16), a total of 980 accepted
species. Leontyev (2015) proposes a total of 8 orders and 14 families.” (Lado & Eliasson, 2017)
