Fungi are Eukaryotic, their bodies consist of hyphae which collectively constitute a mycelium. These are either saprophytic or parasitic and digest food extracellularly. their cell walls are composed of chitin;.

Sexual stage is a zygosporangium; also, coencytic, no dikaryotic stage, plasmogamy and karyogamy not widely separated in time; thought to be the primitive division of the Fungi.
Recognize to genus
Know four types of hyphae and be able to recognize a zygosporangium and to interpret questions in light of your knowledge of the life cycle.
Recognize the various stages of zygosporangial development seen in sexual cultures of Phycomyces.
Sexual stage an ascus with ascospores; also hyphae cellular with incomplete septations, asexual reproduction often by conidia, plasmogamy and karyogamy separated in time resulting in a dikaryotic stage.
Blue mold; the source of penicillin, gives blue cheese its color, produces an abundance of conidia resulting in its blue color; be able to recognize conidia and conidiophores.
Unicellular, cell division by budding, sexual stage an ascus, hence, included in the Ascomycota
Parasite on the leaves of plants. Reproduces vegetatively by conidia, which give infected leaves a powdery appearance, hence, the name. Asci contained in a completely closed ascoma called a cleistothecium. Recognize all structures relating to its life cycle seen in lab.
Recognize microscopic views of hymenial layer, asci and ascospores of Morchella
Sexual structure a basidium. Hyphae septated, but with perforations. Plasmogamy separated in time from karyogamy often with a persistent dikaryotic stage.
Old taxonomic shchemes divided the basidiomycetes into three classes.
Teliomycetes - Rusts and Smuts
Wheat Rust: Puccinia graminis has various types of structions bearing different types of spores. Its life cyle encopasses two different hosts.
Uredinium (plural uredinia) Urediospores Telium (plural telia) Teliospore Aecium (plural aecia) Aeciospores Spermogonium (spermogonia) A brief tour through the wheat rust life cycle
Summer (Uredinial Stage)
Late Summer and Overwintering Stage
Early Spring: Teliospore germination; Basidium and basidiosores
Late Spring: Infection on barberry
Corn Smut (common name)
(Symbiotic relationship between a fungus and an alga or a Cyanobacterium).
Mycorrhizae
( Mutualistic fungi that infect the roots of most plants. Know endomycorrhizae and ectomycorrhizae)
