  1. 1. acloutier2013 copyright Kingdom Fungi By Annie C. Cloutier 2013 for classroom and global learning copyright 2013
  2. 2. acloutier2013 copyright Many different fungi
  3. 3. acloutier2013 copyright Decomposers the work of a fungi is to break down organic and inorganic matter into soil, and nutrients for other plant life. • Hyphae or masses of hyphae (fungal threads) are called the mycelium • Saprobes organisms that live off dead organic matter • most fungi are filamentous • Scientists are debating if some fungi originate from protozoa since they have a flagellum *these are found in the animal kingdom) • Zygotes get converted into a resting spore in chytrid reproduction. • A scientist who studies mushrooms is called a mycologist • Zygote nuclei undergo meiosis (cell division where number of chromosomes is halved-genes of two parents to be combined) • Fungi and be found on the North Pole to desert climates
  4. 4. acloutier2013 copyright Asexual or sexual reproduction ? • Budding • Asexual reproduction condia • Are spores that are produced outside the sporangium • Happens at the tip of the hyphae called a conidiophore • Asci • Tiny finger like sacs form • Where the hyphae of two different sexes become closely associated in the more complex sac fungi • Male antheridia • Female ascogonia produce on the same mycelium

  7. 7. acloutier2013 copyright Shelf or Bracket Fungi called club fungi because they reproduce sexually producing spores at the tip (basidia) of with swollen hyphae that resemble “clubs”

  12. 12. acloutier2013 copyright Blue Cheese dark colors are conidia of a species of Penicillium • What exactly is blue cheese? • Blue cheese is typically made from cow, sheep or goat milk injected with Penicillium cultures that gives it the blue color speckled throughout its white body. Yes, those blue spots are a type of mold, but it is good mold! It can do no harm to you and it makes for an ultra tasty product.
  13. 13. acloutier2013 copyright Penicillium discovery one of the best known medical antibiotics Sir Alexander Fleming 1929 • He discovered that certain bacterium would not grow next to the mycelium of a penicillium mold (fungi) • World War 2 the need for antibiotics to prevent soldier’s wounds from getting infected • Moldy trash was sent to scientist found that cantaloupes made 80% greater quantities of penicillin • Other Soil fungi have been introduced to fight other bacterial infections
  14. 14. acloutier2013 copyright Nature has many solutions for us to discover. Plants are to be cherished.
  15. 15. acloutier2013 copyright Mushroom Fairy Rings found in forest and lawns • Depending on the species of fungus involved and how long it has been growing, the rings may be only a few centimeters to 20 meters (about 65 feet) in diameter. The diameter of some fairy rings may increase by about 20 cm (8 inches) each year. The largest known fairy ring was discovered in France - it is about half of a mile wide and is estimated to be about 700 years old! When mushrooms are not present, less obvious rings of taller, greener grass may indicate the presence of a fairy ring in lawns. These are caused by fungal activity releasing nitrogen, which fertilizes the ground and, for a short time, stimulates growth of grass. A ring of dead grass also may appear inside the lush ring due to the fungal mycelia becoming so dense that water cannot penetrate into the ground. The lack of water, coupled with the depletion of nutrients as they are taken up by the fungus, causes the grass to die. Grass in the center of a larger ring may re-grow as the fungal mycelia in that area die and allow water to penetrate the soil, and nutrients are released from the dead mycelia
