Mushrooms are fungi that decompose and absorb the nutrients of nonliving organic material1. The best substrate for mushroom growth depends on the species. According to mycologist Tom Volk, Agaricus bisporus (the edible white button mushroom) grows well in wheat straw and horse manure, but other composted ingredients are also used2.
Mushroom grow bags and mushroom spawn are available for online purchase. The grow bags include a sterile compost colonized with mushroom mycelium (a mass of hyphae) in a plastic bag. These are typically purchased by consumers who want to grow edible mushrooms at home. The spawn (mycelium propagated on a sterile cereal grain) is typically purchased by commercial mushroom growers2.
On mushroom farms, a suitable compost

It is a layer of organic material (above the compost) that stimulates the initiation of primordia3. It supports the emerging primordia, but does not supply nutrients to the fungus. Mushroom farmers place a casing material (such as peat moss) over the compost to induce fruiting after the compost is colonized with mycelium.
Volk reports that commercial growers maintain the air temperature at approximately 24ºC until the mycelium has colonized the compost and grown through the casing layer. Then, the temperature is dropped to 16-18ºC to promote pinning2.
Since I eat white button mushrooms, I thought it would be interesting to make white button mushroom grow bags and a spore solution. For the grow bags, I used FoodSaver® bags (normally used to vacuum seal food in a home kitchen) and a store-bought compost containing horse manure. For the spore solution, I used a store bought mushroom.
My hypothesis was that sterilized compost in a FoodSaver® bag would yield more Agaricus bisporus than non-sterilized compost in a FoodSaver® bag. The independent variable for this experiment was the sterilization of the compost. The dependent variable was the number of mushrooms grown. I reasoned that sterilization would eliminate other decomposers competing for nutrients in the compost, making it more favorable medium for white button mushroom growth.

Materialism is a poison to society that prevents people from doing what is necessary for them. The novel, “Into the Wild” by Jon Krakauer demonstrates this. The novel is centered on Chris McCandless. He was on his way to graduate from a well-known university. He decides to leave, donating his money and burning the rest. He went into the wilderness, living off the land. He demonstrates materialism by taking only what was on his back. Materialism is a tendency to consider material possessions and physical comfort as more important than spiritual values. The average person requires possession of physical objects in order to be content. Chris shows through his actions that having physical comfort is not needed to acquire satisfaction. In “Into
they require a carbon source to thrive. The nutrient that is taken in by the fungi is
After the conclusion of our experiment we refuted our original hypothesis of, “If the type of fungus (parasite or saprophyte) affects the enzyme activity, and you measure enzymes in lion’s mane an enoki, then the lions mane will have less enzyme activity? ” because we found the opposite was apparent in our experiment. While we though the Lion's mane mushroom (parasite) would have less enzyme activity than that of the Enoki mushroom (saprophyte) because the Lion's mane mushroom grows on a living hardwood tree, while the Enoki grows on a dead hardwood tree. That we saw was that The Lion's mane (parasite) which grows on a living hardwood tree, had more enzyme activity than the Enoki (saprophyte) which grows on a dead hardwood tree.
Satire is a grand literary device used by many authors to subtly make fun of a certain person or group. A way to mock them or make fun of their stupidity, and in the Canterbury tales there is a lot of satire that is discretely hidden between the lines, in forms that may not be so easily noticed in today’s world. Throughout the Canterbury tales, the descriptive lines depict not only fourteenth century England down to the T, but they also reflect Chaucer’s personality and wit. He allowed people to take a deeper look into himself, through the words and descriptions hat can be found in the Canterbury Tales. The Canterbury tales is broken up into many sections and examples of satire can be found in all of them, however, some are more prevalent
A mushroom is a type of fungus. Unlike plants, they don’t need sunlight or seeds to grow.
9. In the research done on the microbial community in the Rhizosphere using two methods, which are the Cultivation-dependent method and Cultivation-independent method. The research and studies done had good results, moreover, the physiological profiling was done in 5 days by the use of several carbon sources. The maximal growth was observed for the 30 degrees celsius- incubated plate by day 3, whereas comparable values were recorded for the room to the temperature-incubated plate by day 5.
Morchella Esculents are a highly sought after edible fungi. The ascomycete is typically found above ground in the spring and summer months of March through June, depending on the locations climate. Despite its popularity among morel “hunters” and ecologists, little is known about the consistent abiotic and biotic indicators of morel mushrooms. It can even be suggested that Morels can be used as a bio-indicator because of how fragile the species is in relation to its surroundings. It has been estimated that there are at least twenty-eight phylogenetically distinct Morchella species around the globe. At least twenty-four of those species can be found in North America and thirteen are species in the Esculenta clade (Stefani, 2010). Morels are morphologically diverse but do not have specific distinctions between species. The varied and inconsistent fruiting pattern of the M. Esculents make it difficult to pinpoint the exact and consistent location of an abundant fruiting of morels.
This forum discussion will be focusing on Mycelium and how it may be used in the construction/building industry. Mycelium are large groups of hyphae, hyphae are the branching filaments or clusters of single cells in a fungus that grow in a web like structure and is the main vegetation part of the fungus. A hyphae is formed when a single female and male fungi fuse and the spore germinates. The fruity or flowering part of the fungus is a mushroom. Fungus is a decomposer and absorbs nutrients from the breakdown of the decomposed material by using its mycelium in a 2 stage process. The mycelium lives inside of decaying wood/logs, soil etc. The hyphae projects enzymes into the decaying wood which works to break down the larger molecular structures or polymers into smaller single molecule or monomers which the mycelium can easily absorb by facilitated diffusion and active transport. The mycelium continues to spread searching for water and food sources, when the food source, or a change in the environment changes like temperature drops or humidity rises, the mycelium will be triggered to produce another mushroom, and they cycle starts all over again with the mushroom producing more spores and releasing them with force in the surrounding area.
Molds are a type of fungi that grow in filaments and produce microscopic spores. Because these spores
Microorganisms such as bacteria, fungus, mold, and yeast are present and common in almost every environment on earth. The normally microscopic organisms can easily be seen using differing types of agar, which creates an ideal environment for the organisms to form colonies, which are groups of hundreds of organisms that can be seen with the naked eye. In order to see individual microorganisms, it is necessary to use the magnification of a high-powered microscope.
Mold classified as fungi, is a microorganism that has over a million different species. Invisible to the bare eye, mold spores go through the air and are regularly found in soil and on rotting matter. However, many times, the mold grows hidden behind walls. Mold can grow at a quick pace. It can become a hazard when a mold spore makes a contact with a surface or attached to skin or ingested with food. Mold comes in an assortment of colors including white, brown, orange, green and black.
Mushrooms are much more than an appealing food source; mushrooms have the ability to dispose of hazardous waste, redesign subway systems better than engineers, and are helpful remedies to treat diseases such as smallpox (video). This organism is the solution to so many everyday problems, and has the potential to sustain life. The mushroom species might be the most useful organic item to help protect and sustain life aside from
Only a small portion of those that live on land is normally visible. Most of the fungus, a complex network of hyphae, grows underground, near the surface. The visible parts of fungi vary greatly in size. Some are so tiny that they cannot be seen without the aid of magnification. Others are quite large. Some mushrooms reach diameters of 8 to 10 inches (20 to 25 centimeters) and heights of 10 to 12 inches (25 to 30 centimeters). Bracket fungi that are 15 inches (38 centimeters) in diameter are fairly common; and mushrooms called puffballs have been known to grow to 60 inches (152 centimeters) in diameter.
Mushrooms are the food bodies of evolved fungi. When a person is intoxicated by the intake of harmful mushrooms, they can suffer from numerous impacts. This digestion of toxic mushrooms is referred as the mushroom poisoning. These toxin mushrooms possess similar looks as those of other edible mushrooms. Therefore, they are confused with the usual mushrooms. Mushrooms are widely grown in many parts of this world; however, among the thousands of mushroom species, only a hundred can cause harmful impacts on human health. Moreover, about twenty species can cause severe impacts on human life.
