- Fungal phylogeny was once based on morphology and heterotrophic nutrition - Now use molecular analysis of fungal DNA and distinguishing fungal characteristics. -Examples of fungi characters include flagellation, cell wall structure, mitochondrial structure, and the site of meiosis to determine a modern monophyletic classification - Blastocladiomycota, the phylum containing the chytrid fungi, are estimated to be the oldest fungal group - Blastocladiomycota are unique in that meiosis is sporic, the result is an alternation of generations - Glomeromycota, the arbuscular mycorrhizal associates, were once known as zyomycetes until they were discovered to not produce zygospores - Zygomycota, the group known for its parasitic species containing septal pore plugs, are not a formal monophyletic group, but are placed in three or more subclades informally. -Ascomycota

Unformatted text preview: are divided into three subphyla, Taphrinomycotina, Saccharomycotina, and Pezizomycotina, which contain fungi responsible for dispersing tree diseases.-Basidiomycota also have three subphyla, Pucciniomycotina, Ustilaginomycotina, and Agaricomycotina, which contain fungal parasites and plant pathogenic fungi-Molecular analysis has also provided earlier dates on fungal evolution than the fungal fossil records, with estimates of a one billion year history- Fungal communities emerged during the Devonian, which contained chytrid, Glomeromycota, and Ascomycota.-Fungal diversity grew with the rise of terrestrial environments, even before the rise of wingless insects-Plants, winged insects, and fungi grew more diverse during the Carboniferous period- Many insects that appeared during the Mesozoic, such as wood wasps, are associated with fungi to the modern day...
