Fungi
What are the fungi? Mushrooms, molds, yeasts, athlete's foot diseases, rusts, and smuts All are filamentous or unicellular. Individual filaments are termed hyphae. A mass of hyphae is the mycelium (the feeding stage) Walls of the filaments are of cellulose with chitin Cells are eucaryotic; that is, they contain nuclei, mitochondria, other organelles Nutritionally, all fungi are heterotrophic, mostly aerobic Saprophytic--live off dead organic matter Parasitic--obtain nutrients by penetrating tiny branches (haustoria) into a host Sexual--gametangia produce sperms and eggs Decomposers of organic materials--important recyclers of matter The representative genus I shall use is Saprolegnia (can be collected from freshwater habitats by using apple baits in wire cage) A true mycelium, of tubular threads The hyphae have 2N nuclei (numerous)
Rules for selecting wild mushrooms as food: DON'T Production of ascospores, if the proper species of alga is encountered, a new lichen may be produced. Antheridia--------> sperms (gametes)
