Amastigomycota

Amastigomycota or Eufungi is a clade of fungi. It includes all fungi without flagella or centrioles, and with unstacked Golgi apparatus cisternae. Members of this clade are Dikarya and the traditional paraphyletic assemblage "Zygomycota",^[1][2][3] now divided into several monophyletic phyla.^[4]

At the time, the monophyly of Fungi (Eumycota) was not fully certain. Cavalier-Smith considered one scenario where Eufungi could be ancestral or basal to other eukaryotes due to their relatively simple cytology and small genome, though he favoured the hypothesis of fungal monophyly,^[2] which is now the consensus.^[4]
