Club Fungi Section 8-4
2
Club Fungi Club fungi are named for the structure that produces their sexual spores. This structure is called a basidium which means “club”. These are located on their fruiting bodies. Most club fungi are saprophytes.
3
Mushrooms Have you ever eaten a mushroom? If so, you ate a club fungi. Mushrooms are made up of many hyphae, and they have a cap lined with gills and basidia. When spores mature, they drop to the ground. Life cycle on page 133
4
Rusts and Smuts They are parasitic fungi that often cause severe diseases in plants and crops. They do not form fruiting bodies. They form sexual spores on basidia.
5
Sac Fungi 8-3
6
Sac Fungi Unlike molds, sac fungi have cross walls in their hyphae which have tiny spores in them. The sexual spores are produced in tiny sacs, hence their name. They also produce asexual spores.
7
Yeasts Single-celled fungi that usually do not form hyphae. They form filaments under certain conditions. Obtain their energy through a respiratory process called fermentation. Often reproduce by budding.
8
Cup Fungi Saprophytes that grow in soil. The sexual spores are produced on the fruiting body. Hyphae line the inside of the fruiting body. These hyphae produce the spore filled sac of the cup fungus. Spores remain inside the sac until they mature. The sac then bursts open
9
Lichens Two organisms living together: a fungus and an alga. The two have a symbiotic relationship: each organism helps the other. Alga provides nutrients, the fungus provides water and carbon dioxide needed for photosynthesis.
