Mushrooms


The Sierra Outdoor School has been getting much needed rain showers, and with those showers appear nature’s oddballs—mushrooms.  Mushrooms are part of the Fungi Kingdom and are actually only a small part of a much larger organism.





Apples of the dirt
A mushroom is much like an apple on a tree—existing to carry and spread seeds.  The mushroom version of a seed is called a spore.  The “tree” a mushroom grows on is called the mycelium, an underground network of hair-like fibers.  The mycelium can be as small as a few square feet and as large as several thousand acres.

What appears to be cob webs is actually mycelium.
Mushroom examples and their lifestyles
Shaggy Mane—Shaggy Mane mushrooms grow in the forest here at SOS but can also be found growing out of lawns in the suburbs.  They are characterized by a “shaggy” cap growing on the end of a stalk.  The underside of the cap contains gills from which spores will eventually drop.  Shaggy Mane is a common example of a saprophyte, an organism which gets its energy and nutrients by digesting decaying plant matter.

Puffball—Unlike the Shaggy Mane, the Puffball lacks gills and a stalk.  Late in its life cycle it will dry out and emit a “puff” of spores.  Puffballs are mycorrhizal, which means they get their energy from trees through a mycelium to root connection .  The mycelium in turn acts as an extension of the tree's root networks and brings in more water.  
A trio of puffballs.
Turkey Tail—Can you guess how this mushroom got its name? Turkey tail is part of a group of mushrooms called polypores. Instead of having gills, polypores have a system of pores(like your skin) on their underside.  Like the Shaggy Mane, Turkey Tail is a saprophyte, getting its energy by digesting the wood it grows on. 



So the next time you see a mushroom remember:
1) An underground network of mycelium lies beneath it.
2) Their function is to spread spores for reproduction.
3) They assist in decomposition and can help the roots of trees.
4) They come in many shapes and sizes.

Give Plants a Chance: Erosion and Giant Sequoias

What is Erosion? Erosion is the gradual degradation (breaking down) of rock and other natural material, by wind, water, gravity, and even animals. Erosion happens all around us on hillsides, the edges of riverbeds, beaches, and cliff walls. It is an entirely natural and necessary process; erosion is responsible for the dispersion and recycling of rocks and minerals into sediment, which enriches soil and provides opportunities for new life to emerge!

          However, human induced erosion is not natural, nor beneficial to our local environment. Scientists have estimated that global rates of erosion have increased 10-40 times its natural rate, due to human influence and activity. If you are looking for signs of human induced erosion, it is particularly obvious alongside walking trails in parks and forests.



Every year, our Sierra Outdoor School Naturalists take hundreds of of students on field trips to Calaveras Big Trees State Park, aptly named for the beautiful Giant Sequoia …
