F0007 - Phylum Zygomycota and the new classification - Univap

Recent phylogenetically basedreclassifications• Zygomycota, Zygomycotina, Zygomycetes andEntomophthorales– Until such a time as the molecular studies clarify theoverall relationships among these fungi and establish a newset of phyla, my practical advice is to continue to use thesediscontinued phylum, subphylum and class names since (1)their meanings remain unambiguous in terms of the fungiincluded, and (2) journals may remain unwilling or unablefor some time still to handle the concepts of new subphylawith unassigned status (‘incertae sedis’).Zygomycota DENR 7Classificação HierárquicaReino FungiFilo ZygomycotaSubfilo MucormycotinaClasse ZygomycetesOrdem MucoralesFamilía MucoraceaeGênero MucorEspécie: Mucor mucedoZygomycota DENR 8Zygomycota• Duas Classes–Classe Zygomycetes–Classe TrichomycetesBased on 18S + 28S + 5.8SZygomycetesTrichomycetesFrom White et al. 2006.
