Title: Chytridiomycota


1
Phylogeny of Kingdom Fungi
Chytridiomycota
Chytridiomycota

Zygomycota
Glomeromycota
Ascomycota
septate hyphae dikaryon sporocarps
Basidiomycota
2
Classification of the phylum Ascomycota
Subphylum Taphrinomycotina - early diverging
Ascomycota - may not be a single group -
yeasts, filamentous, dimorphic species
Subphylum Saccharomycotina - true yeasts
- some species with filamentous stages - no
sporocarps - no ascogenous hyphae Subphylum
Pezizomycotina - the ascocarp-forming
Ascomycetes - filamentous - some species with
yeast stages

Taphrina
  • Taphrinomycotina
  • - consists of at least 4 basal lineages
  • Taphrinales - Taphrina deformans
  • Schizosaccharomycetales - Schizosaccharomyces
  • Pneumocystidiales - Pneumocystis
  • Neolectales - Neolecta

  • Saccharomycotina - true yeasts
  • Saccharomycetales
  • budding yeasts
  • Saccharomyces cerevisiae
  • brewers yeast
  • bakers yeast
  • Candida albicans
  • common yeast infections
  • no ascogenous hypha
