A comprehensive phylogenetic classification of the kingdom Fungi is proposed, 
with reference to recent molecular phylogenetic analyses, and with input from 
diverse members of the fungal taxonomic community. The classification includes 
195 taxa, down to the level of order, of which 16 are described or validated 
here: Dikarya subkingdom nov.; Chytridiomycota, Neocallimastigomycota phyla 
nov.; Monoblepharidomycetes, Neocallimastigomycetes class. nov.; 
Eurotiomycetidae, Lecanoromycetidae, Mycocaliciomycetidae subclass. nov.; 
Acarosporales, Corticiales, Baeomycetales, Candelariales, Gloeophyllales, 
Melanosporales, Trechisporales, Umbilicariales ords. nov. The clade containing 
Ascomycota and Basidiomycota is classified as subkingdom Dikarya, reflecting the 
putative synapomorphy of dikaryotic hyphae. The most dramatic shifts in the 
classification relative to previous works concern the groups that have 
traditionally been included in the Chytridiomycota and Zygomycota. The 
Chytridiomycota is retained in a restricted sense, with Blastocladiomycota and 
Neocallimastigomycota representing segregate phyla of flagellated Fungi. Taxa 
traditionally placed in Zygomycota are distributed among Glomeromycota and 
several subphyla incertae sedis, including Mucoromycotina, 
Entomophthoromycotina, Kickxellomycotina, and Zoopagomycotina. Microsporidia are 
included in the Fungi, but no further subdivision of the group is proposed. 
Several genera of 'basal' Fungi of uncertain position are not placed in any 
higher taxa, including Basidiobolus, Caulochytrium, Olpidium, and Rozella.
