Reproduction-
Asexual- Uses spores
Sexual- Fuses with other fungi to create a zygote.

How they spread- Spores carried by wind or reproducing sexually.

Classification of fungi- They are classified by structure and method of reproduction.

Zygomycetes- Common molds. Ex Black bread mold.

Ascomycetes-Sac fungi. This is also the largest fungi phylum. Ex Yeast.
Ascus-The sacs in ascomycetes in which the sexual spores are formed.
Conidia-Tiny spores formed on tips of hyphae.

Basidiomycetes- Club fungi. A Basidium is found on the gills of that grow on the underside of the mushroom caps. In addition to mushrooms, basidiomycetes include shelf fungi, puffballs, earthstars, jelly fungi, and plant parasites.

Deuteromycetes-Imperfect fungi. This phylum is composed of all those fungi that are not placed in other phyla because researchers have never been able to observe a sexual phase in their life cycles. Ex Penicillium

Ecology of fungi
-
Decomposers- Acts as an essential role in returning nutrients to the earth
Parasites- Can kill plants, and hurt people and animals with infections irritations.
Symbiotic Relationships- Works with plants to obtain a source of energy while protecting the plant from the suns rays.
