Characteristics

  • Fungi are eukaryotic heterotrophs

  • Along with bacteria they are major decomposers

  • Many are saprophytes which means they live off dead material.

  • Most reproduce both sexually and asexually.

  • Fungi are found almost everywhere on earth.

  • Their cells have cell wallsmade of chitin.

Toenail fungus

  • 35 million infected in US

  • Can spread from person to person

  • Also called “onychomycosis”


Lichen

Lichen

  • Lichen: A partnership between a fungus and an algae.

  • The algae provides food for the fungus.

  • The fungus provides a place for the algae to live.


Lichen1

Lichen

There are three forms of lichens:

  • Crustose:paint-like crusts that are tightly attached to trees and rocks


Fungus

  • Foliose:leaf-like


Fungus

  • Fruticose:moss-like, branching, the most three dimensional of all the lichens


Parts of a mushroom

Parts of a Mushroom

  • Fruiting body:grows above ground

    • Stalk(Stipe):main support of mushroom

    • Ring (annulus):skirt of tissue circling stalk

    • Cap: top of mushroom

    • Scales:flakey surface of the cap

    • Gills:underside of cap (produce spores)

    • Spores:reproductive structures

  • Mycelial threads:Underground network of hyphae.

    • Hyphae: long strands of cells; make up the body of the fungi.
