Kingdom Fungi - monophyletic Chytridiomycota • oldest group of fungi • mostly aquatic • flagellated gametes (they swim) • chitin strengthening cell walls Zygomycota • mostly terrestrial • living in soil or on decaying plant & animal matter • zygosporangia (from sexual reproduction) metabolically inert -release haploid spores in favorable conditions
Kingdom Fungi - monophyletic Glomeromycota (AM fungi) • arbuscularmycorrhizal fungi • previously considered zygomycota • aseptate hyphae • reproduce asexually w/ large spores with many nuclei • mutualistic with vascular plants • not known to grow separately from plants or cynobacterialpartners
Kingdom Fungi - monophyletic Ascomycota • includes morels & most yeasts & fungi within lichens • terrestrial & aquatic • many asexual w/o sexual stage Basidiomycota • produce spores in a club-shaped structure called a basidium • important decomposers & mycorhizal partners • diverse fruiting bodies – e.g., mushrooms, puffballs, & shelf fungi
