Later, much more handy system of classification was proposed by Gwynne-Vaughan and Barnes (1926). In their classification, Myxomycetes were not considered as fungi and were included by them as forms resembling fungi.

Later, C. J. Alexopoulos and C. W. Mims (1979) placed fungi and slime molds under the kingdom of their own, called Myceteae under the superkingdom Eukaryonta. The kingdom is divided into three divisions and further the divisions are divided into sub-division, class and form-class.
Ainsworth G. C. (1966, 71, 73) proposed a more natural system of classification of fungi. This classification is based on morphology, especially of reproductive structure. He includes fungi along with slime molds under the kingdom Mycota.
Myxomycota i.e., slime molds and Eumycota or true fungi. Divisions are subsequently divided into subdivision, class, subclass, order, family and then to genus. According to his classification, division ends in mycota, subdivision in mycotina, class in mycetes, subclass in mycetidae order in ales and family in aceae.
These fungi are all related because of their parasitic habit, many of these taxa producing haustoria. These are also similarities in zygospore structure, especially in suspensor morphology of many taxa. Some spp. of Syncephalis (Piptocephalidaceae) produce lobed appendages that resemble similar structures formed by some taxa of Cochlonema (Cochlonemataceae). Some Cochlonemataceae and Zoopagaceae spp. produce spores similar to those formed by members of the Piptocephalidaceae. Spores in taxa of the Helicocephalidaceae are similar to those formed by Syncephalis spp. (Piptocephalidaceae)(Benjamin, 1979).
