For more information on ToL tree formatting, please see Interpreting the Tree or Classification. Despite their diversity in many features, the Ascomycetes possess certain common unifying characteristics, namely, the somatic body composed of a loose, indefinite mass of septate mycelium; the mode of asexrual reproduction; and sexual reproduction. They produce motile cells at some stage in their life cycle. Its reproductive cycle includes both asexual and sexual phases. The evolutionary record shows that the first, recognizable chytrids appeared during the late pre-Cambrian period, more than 500 million years ago. Most chytrids are unicellular; a few form multicellular organisms and hyphae, which have no septa between cells (coenocytic). The oldest fossil fungi so far known are chytrid-like forms from the Vendian of northern Russia. The Phylum Chytridiomycota (chytrids) is one of the five true phyla of fungi.
