Constantine J. Alexopoulos , often alongside C.W. Mims, developed a widely recognized phylogenetic classification system for fungi. In their 1979 revision, they placed fungi and slime molds in the under the Superkingdom Eukaryonta. This system is primarily based on morphology, reproductive modes, and life cycles. The Kingdom Myceteae is divided into three major divisions: Systematics of the Fungi alexopoulos classification of fungi

This division encompasses the vast majority of organisms recognized as fungi. Alexopoulos further subdivided Eumycota based on the presence or absence of motile spores (zoospores) and the type of sexual reproduction. (Fungi Imperfecti; those lacking a known sexual stage)

| Subdivision | Sexual Spore | Asexual Spore | Hyphal Structure | Example | | :--- | :--- | :--- | :--- | :--- | | | Oospore | Zoospore (motile) | Coenocytic (non-septate) | Phytophthora | | Zygomycotina | Zygospore | Sporangiospores | Coenocytic (non-septate) | Rhizopus | | Ascomycotina | Ascospore (in Ascus) | Conidia | Septate | Saccharomyces | | Basidiomycotina | Basidiospore (on Basidium) | Rare/Absent | Septate (with clamp connections) | Agaricus | | Deuteromycotina | None observed | Conidia | Septate | Penicillium | The Kingdom Myceteae is divided into three major

These fungi lost their flagella and adapted to terrestrial life. They lack septa (cross-walls) in their hyphae for most of their life cycle (coenocytic).

Classes: Chytridiomycetes , Hyphochytridiomycetes , Plasmodiophoromycetes . (Biflagellate fungi) Class: Oomycetes (often called "water molds"). 3. Division: Amastigomycota (Non-motile Fungi)
