Glomeromycetes • The glomeromycetes (phylum Glomeromycota) were once considered zygomycetes • They are now classified in a separate clade • Glomeromycetes form arbuscular mycorrhizae

You should now be able to: 1. List the characteristics that distinguish fungi from other multicellular kingdoms 2. Describe the life cycles of Rhizopus stolonifer and Neurospora crassa 3. Distinguish among zygomycetes, ascomycetes, and basidiomycetes 4. Describe some of the roles of fungi in ecosystems, lichens, animal-fungi mutualistic symbioses, food production, and medicine and as pathogens
