  Good day, knowledge adventurers. Welcome to Kit Cast Daily, where
• 0:38
  every episode takes you on a journey through sports, science,
• 0:42
  history, and all the fascinating corners of our world.
• 0:46
  Today we are exploring mushrooms, the surprising,
• 0:50
  helpful, and sometimes mysterious members of the living
• 0:54
  world that pop up in forests, yards, and even grocery stores.
• 0:59
  So let's get on with today's episode.
• 1:12
  First, what exactly is a mushroom?
• 1:15
  A mushroom is the fruiting body of a fungus.
• 1:18
  Think of a fungus as a large hidden network living in soil,
• 1:23
  wood, or other material. The mushroom is the part you can
• 1:26
  see above ground, and its main job is to spread spores, which
• 1:30
  are tiny cells that can grow into new fungi.
• 1:34
  The bigger hidden part is called mycelium.
• 1:37
  It looks like a web of thin white threads that weave through
• 1:40
  soil or wood. Those threads absorb nutrients
• 1:44
  and water. Quick yes or no question.
• 1:47
  Do mushrooms use sunlight to make their own food like plants
• 1:50
  do? No, mushrooms do not make food
• 1:57
  from sunlight. Instead, fungi get energy by
• 2:00
  breaking down leaves, wood, and other organic matter, or by
• 2:05
  trading nutrients with living plants.
• 2:07
  Let's look at the parts of a typical mushroom.
• 2:10
  Many of a cap on top, which can be smooth, bumpy, or scaly.
• 2:15
  Under the cap are gills or tiny pores.
• 2:19
  This is where spores are made and released.
• 2:22
  The cap sits on a stem which holds the cap up, so wind or
• 2:26
  passing animals can help spread the spores.
• 2:29
  Some mushrooms have a ring around the stem or a cup at the
• 2:32
  base called a vulva. These features help experts
• 2:35
  identify species. Not all mushrooms look the same.
• 2:40
  Some are small and cup shaped, some look like shells on trees,
• 2:44
  and some are round like puff balls.
• 2:47
  Spores are amazing. They are so small you need a
• 2:50
  microscope to see them. One mushroom can release
• 2:53
  millions of spores into the air. In dry weather, wind carries
• 2:58
  them. In rainy weather, falling drops
• 3:01
  can splash them away. Animals can also help.
• 3:04
  A slug or a beetle might move spores on its body, and birds
• 3:09
  can carry spores on their feet or feathers.
• 3:12
  Did you know some mushrooms drop their spores and patterns that
• 3:15
  can be seen if you place a cap on aer overnight.
• 3:18
  This is called a spore print and the color can be white, brown,
• 3:22
  black or even pink. Mushrooms are important helpers
• 3:26
  in nature. Many are decomposers.
• 3:30
  That means they break down dead leaves, fallen branches and
• 3:33
  other once living material. This process returns nutrients
• 3:38
  to the soil. Trees, grasses, and garden
• 3:41
  plants use those nutrients to grow.
• 3:44
  If you have ever raked a pile of leaves and later found them
• 3:47
  crumbling into dark, rich material, fungi helped make that
• 3:51
  happen. In forests, fungi helped keep
• 3:54
  the cycle of life moving by clearing away old plant parts
• 3:58
  and making space and food for new life.
• 4:01
  Some fungi forms special partnerships with plants.
• 4:05
  A common partnership is called mycoriza.
• 4:08
  In this teamwork, the fungus wraps around or even goes inside
• 4:13
  plant roots. The fungus helps the plant by
• 4:16
  bringing water and minerals like phosphorus.
• 4:19
  In return, the plant sends sugars to the fungus.
• 4:23
  Many trees, including Pines and oaks, grow better with
• 4:27
  mycorrhizal fungi. Gardeners sometimes add
• 4:31
  mycorrhizal spores to soil when planting to help new roots get
• 4:35
  started. Did you know many wild orchids
• 4:37
  rely on fungi to grow from tiny seeds into healthy plants?
• 4:47
  Let's play a quick trivia round that teaches something brand
• 4:50
  new. What is the largest Organism on
• 4:53
  land measured by area? It is a honey fungus in Oregon
• 5:00
  in the United States. Scientists have measured it
• 5:03
  spreading through the soil over about 2.4 square miles or 6.2
• 5:09
  square kilometers. It is a single genetic
• 5:12
  individual connected by mycelium, and it is thousands of
• 5:15
  years old. Mushrooms also interact with
• 5:19
  many animals. Squirrels, deer, insects, and
• 5:22
  snails eat different kinds of fungi.
• 5:25
  In turn, some fungi trap small soil organisms like microscopic
• 5:30
  worms, helping balance tiny ecosystems underground.
• 5:34
  Did you know truffles are underground mushrooms that
• 5:37
  release strong scent so animals like pigs or trained dogs can
• 5:41
  find them, dig them up, and spread the spores.
• 5:44
  Mushrooms and people have a long history together.
• 5:47
  Many mushrooms are food. Grocery stores often sell button
• 5:52
  mushrooms, which are the young form of the species Agarica
• 5:55
  spice forests. If they grow larger and the caps
• 5:59
  open, they are called Portobello.
• 6:01
  Shiitake mushrooms come from logs or blocks of sawdust where
• 6:05
  their mycelium has grown. Oyster mushrooms have soft fan
• 6:10
  shaped caps and grow in layered clusters.
• 6:13
  Chefs and families use mushrooms in soups, omelets, pizzas, stir
• 6:18
  fries and salads. Mushrooms add flavor, fiber and
• 6:22
  minerals like selenium and potassium.
• 6:26
  Safety is important. Some wild mushrooms can make you
• 6:29
  very sick if you eat them. Never taste wild mushrooms
• 6:33
  unless a trained expert has identified them as safe.
• 6:37
  Many edible and harmful species look alike, and even adults use
• 6:41
  careful guides and microscopic clues to check.
• 6:45
  Good rules include not touching or picking unknown mushrooms and
• 6:49
  asking a trusted adult before handling any wild fungi.
• 6:53
  People who study mushrooms and help identify them are called
• 6:57
  mycologists. Here is another brand new
• 7:05
  question for you. Do some mushrooms glow in the
• 7:08
  dark? Yes.
• 7:13
  Certain species are bioluminescent, which means they
• 7:16
  produce their own light. Examples include the Jack O
• 7:20
  Lantern mushroom in North America and the ghost fungus in
• 7:24
  Australia. The glow can help attract
• 7:26
  insects that spreads spores. Scientists also learn from fungi
• 7:30
  in the lab. Yeast, which is a single celled
• 7:34
  fungus, helps bread dough rise by producing gas bubbles that
• 7:38
  make it fluffy. Some molds, another group of
• 7:41
  fungi, have led to important medicines.
• 7:44
  Did you know the antibiotic penicillin was first discovered
• 7:48
  from the mold penicillium, which can stop some bacteria from
• 7:51
  growing? People farm mushrooms in special
• 7:54
  indoor rooms. Workers prepare a growing
• 7:57
  surface called substrate, often made of pasteurized straw,
• 8:02
  sawdust or compost. Then they mix in mushroom spawn,
• 8:06
  which is a material full of white mycelium.
• 8:10
  The room is kept at the right temperature and humidity.
• 8:13
  After the mycelium spreads through the substrate, small
• 8:17
  mushroom pins appear. Within days, the pins become
• 8:21
  full size mushrooms ready to harvest.
• 8:24
  Mushroom farms reuse water carefully and keep rooms very
• 8:29
  clean to prevent unwanted molds from taking over.
• 8:32
  Let's try a brand new speed question.
• 8:35
  How fast can some mushrooms push up from the ground in one day?
• 8:38
  Under the right moisture and temperature, some species can
• 8:45
  grow about an inch or around 2.5 centimeters in a day.
• 8:51
  They absorb water quickly and their cells expand, which can
• 8:55
  make a mushroom seem to appear almost overnight on a lawn after
• 8:59
  rain. Mushrooms come in many shapes
• 9:07
  and textures. Puff balls release clouds of
• 9:10
  spores when they burst. Morels have honeycomb like caps
• 9:14
  and are prized by experienced foragers.
• 9:17
  Shelf fungi grow like steps on tree trunks and stumps.
• 9:21
  Coral fungi branch like tiny bushes.
• 9:25
  Did you know there are mushrooms that smell like popcorn, Maple
• 9:29
  syrup or garlic? Time for a new yes or no
• 9:32
  question that adds a fresh detail.
• 9:35
  Can a mushroom spore color help scientists identify its species?
• 9:42
  Yes, the color of a spore print is an important clue.
• 9:47
  It can be white, cream, brown, black or other shades, and
• 9:52
  experts use it along with cap shape, gill spacing and habitat
• 9:56
  to make accurate identifications.
• 9:59
  Fungi also help clean up environments.
• 10:01
  Some species can breakdown oils, dyes and certain pollutants in a
• 10:06
  process called micro remediation.
• 10:09
  Researchers test these fungi on contaminated soil to see which
• 10:14
  ones work best. Gardeners use wood chip beds
• 10:17
  with mushroom mycelium to help filter stormwater in yards and
• 10:21
  parks. Here is a final brand new trivia
• 10:24
  challenge. How many spores can a giant
• 10:27
  puffball mushroom hold inside? Scientists estimate that a
• 10:34
  single giant puffball can contain several trillion spores.
• 10:38
  When the skin breaks, wind and raindrops can carry those spores
• 10:42
  far across fields and forests. Did you know some lawn mushrooms
• 10:46
  grow in large ring shapes because the underground mycelium
• 10:50
  spreads outward in every direction, using up nutrients in
• 10:54
  the center and fruiting at the edge where food is still
• 10:57
  available. If you've seen a circle of
• 10:59
  mushrooms after a wet week, you have witnessed this growth
• 11:02
  pattern. Also, did you know that
• 11:05
  Antarctica has fungi living in very cold, dry rocks, showing
• 11:10
  just how tough and adaptable fungi can be?
• 11:18
  Let's recap what we learned today.
• 11:20
  Mushrooms are the fruiting bodies of fungi, and their main
• 11:24
  job is to spread spores. The real body of the fungus is
• 11:28
  mycelium, which lives in soil, wood, or other material and
• 11:34
  absorbs nutrients. A typical mushroom has a cap,
• 11:37
  gills or pores, and a stem, and some also have a ring or a cup
• 11:42
  at the base. Fungi do not make food from
• 11:45
  sunlight. They get energy by breaking down
• 11:48
  organic matter or by trading nutrients with plants.
• 11:51
  In partnerships called mycorrhizae, mushrooms play key
• 11:55
  roles in ecosystems by recycling dead material and supporting
• 11:59
  plant growth. Many animals eat mushrooms, and
• 12:02
  people farm edible species like button, shiitake and oyster
• 12:07
  mushrooms for meals. Safety matters, so only trained
• 12:11
  experts should identify wild mushrooms for eating.
• 12:15
  Fungi have helped people develop useful products, including
• 12:18
  bread, yeast and important medicines.
• 12:21
  Some species glow in the dark, some grow very quickly after
• 12:25
  rain, and a giant puffball can hold an enormous number of
• 12:29
  spores. From forests to farms to science
• 12:32
  labs, mushrooms and their fumble relatives are busy workers that
• 12:37
  keep our world healthy and full of life.
