Different Types of Mushrooms
There are many different kinds of mushrooms. One of the most common of them are Pleurotus Ostreatus (oyster mushroom), Pleurotus eryngii (King Oyster), Agaricus subrufescens (almond mushroom), hypsizygus ulmarius (white elm mushroom or elm oyster), Hypsizygus tessulatus (shimeji), Coprinus comatus (shaggy mane), Lentinula edodes (shiitake), Hericium erinaceus (Lios' Mane), and Grifola Frondosa (maitake). Out of these, the most commonly grown are Sporophores which are chiefly in the agaric family (Agaricaeae). These are the kind that grow in your yard-in the grass/forest-outside along the barks of trees. There are over three thousand different types of mushrooms growing in North America alone. Some are very common, but many are found only rarely in special habitats.
Mycelia
Mushroom mycelia may live hundreds of years or die in a few months, depending on the available food supply. As long as nourishment is available and temperature and moistures are suitable, a mycelium will produce a new crop of Sporophores each year during its fruiting season. Fruiting bodies of some mushrooms occur in acs or rings called fairy rings. The myscelium starts from a spore falling in a favorable spot and producing strands (hypahe) that growing all directions, eventually forming a circular mat of underground hyphal threads.
Polypores
Polypores usually grow on living or dead trees, sometimes in destructive pests, or in somewhat damp areas. Many of them renew growth each year and thus produce annual growth layers by which their age can be estimated. Examples include the dryad's saddle, the beefsteak fungus, the sulfur fungus, and species of the genera Fomes and Trametes.

This lab was designed to determine the identity of “mystery spores” by growing them on an agar lined petri dish and observing them growing over the course. While their growth, we learned about various divisions within kingdom Plantae and their characteristics. Using this information about different divisions within kingdom Plantae and our observations of the mystery spores, we created a phylogenetic analysis comparing the mystery spores with the following divisions: Chlorophyta (green algae), Marchantiophyta (liverworts), Bryophyta (mosses), and Pteryophyta (ferns). According to this analysis, we concluded that the mystery spores belonged to the division Pteryophyta. 2.
Results obtained in lab as well as scientific research prove that as temperatures increase the percent of crossing over increases as well. Introduction: Sordaria fimicola belongs to the kingdom of fungi and is part of the phylum Ascosmycota. This fungus habitat is in the feces of herbivores. As many fungi, Sordaria have one life cycle which is haploid/ diploid. It is commonly exited as a haploid organism, but when the mycelium of two individuals meets, the result is a diploid zygote.
Sordaria fimicola is a species of microscopic fungus that is an Ascomycete and are used to test for genetic variation in the lab setting (Sordaria fimicola: A Fungus used in Genetics, Volk). These organisms are what are called model organisms, or species that has been widely studied usually because it is easy to maintain and breed in a laboratory setting and has particular experimental advantages (Sordaria fimicola, Volk). S. fimicola, because it is in the Ascomycota phylum, have a distinguishing reproductive structure called the ascus, which is surrounded by the perithecium. This cylindrical sac-like structure houses 8 haploid spores; created through meiosis to produce 4 haploid spores and then mitosis to make 8 (Lab Manual, pg. 59-68). Based on the genotype they will vary in order and color. There are 3 different ratios that can arise from the 8 ascospores: 4:4, 2:2:2:2, and 2:4:2 (black/wild type and tan coloration). The 4:4 ratio suggests that no crossing over had occurred because there is no difference in order of the color parents that were mated. The two other ratios suggest genetic recombination, or crossing over, because of the
All over this planet from the ocean floor to the forests and jungles some form of Fungi can be present. Though they can be found in many different forms such as mold yeast, the most commonly known is the Mushroom. Found in the wild on dead plant and animal matter, the mushroom is nothing more then the fruit of a fungus spore and can be a nutrisous food. There is a specific Genus of these Fungi that have a unique chemical inside of them. Psilocybin or its chemical name Dihydrogen Phospate is a naturally occuring compound with strong Psychoactive properties.
Cell cycle events portray some differences between different living things. In all the three living things, their cells divide, a process referred to as mitosis. The mitosis stage differs and it encompasses four phases. During development, the cell cycle functions endlessly with newly created daughter cells directly embarking on their path to mitosis. Bacteria cells separate forming two cells after every thirty minutes under favorable conditions. However, the eukaryotic cells take quite longer compared to bacteria cells to develop and divide. Nevertheless, in both animals and plants, cell cycle is usually highly regulated to prevent imbalanced and excessive growth. Both animals and plants are known as eukaryotes meaning that their DNA exists inside their cells’ nuclei. Therefore, their cells as well as mitotic processes are similar in various ways (Eckardt, 2012).
The life cycle of Hydnum repandum is fairly simple, as you can see from Figure 2. It falls into the subdivision of Eumycota, called Basidiomycotina (Ross 18). This group contains many large, fleshy fungi,
The gametophytes used in this experiment are of C-ferns. They tend to mature and produce spores at temperature of 28oC and conditions of high humidity. The spores that germinate first are hermaphrodites. Hermaphrodites tend to produce a pheromone called antheridiogen. It is this pheromone that causes later germinating spores to become male.
Tyrosinase is an enzyme found in Portabella mushrooms. Tyrosinase is the enzyme most responsible for the brown color of Portabella mushrooms, as it is found in larger amounts than other pigmentations. Tyrosinase is also found in Tyrosinase vesicles in the cell wall of Portabella mushrooms. Tyrosinase plays a huge role in Portabella mushrooms in that it is active in most chemical reactions including oxidation, phosphorylation and other important mechanisms within the cell. The journal article examines the biochemical characteristics of Tyrosinase in Portabella mushrooms by specifically extracting it from the gill tissue. In order to effectively examine Tyrosinase, purification of this enzyme was to be extracted which resulted in difficulties because mushroom gill tissue is small in size while the Tyrosinase enzymes are abundant in such tissue. Adsorbents and precipitation methods were used to isolate Tyrosinase. These methods, however; were not successful as they either only provided a small amount of the enzyme or decreased the enzymatic activity desired for ob...
The fungus sclerotinia sclerotiorum over winters as sclerotia either in the soil or in stubble at the soil surface (Morton and Hall, 1989). If the weather (moisture and temperature) is favorable, small mushroom-like structures called apothecia will be produced on the sclerotia. Each sclerotia can several apothecia. Apothecia can produce millions of spores called ascospores. Ascospores will be released in air when the apothecia is mature. Some ascospores land on canola plants and infect dead canola tissues like fal...
...l keystone includes fungi, Douglas-Fir and the Flying Tree Squirrel. The squirrels eat truffles made by fungi which are of an important tree species. The squirrel then spreads these fungi in the forest by leaving it in its feces. The fungi play a main part in the old growth forests and effect the growth and health of many northwestern trees.

I had formerly assumed it was established based on the mushy texture of the fungi. Emerson also assesses the etymology of words. He writes, “Words are signs of natural facts. The use of natural history is to give us aid in supernatural history: the use of the outer creation, to give us language for the beings and changes of the inward creation. Every word which is used to express a moral or intellectual fact, if traced to its root, is found to be borrowed from some material appearance ”(22). The concept of how a name originates from and how it pertains to nature and walking consumed a chunk of my walk. Why is a mushroom called a mushroom? Emerson states that words represent particular phenomena in nature, which occurs to contribute to language which is the expression of ourselves. He proposes that all words convey an intellectual and moral meaning which can be etymologically traced back to roots originally attached to material objects and material appearance. Now I assume mushroom’s etymology originates not only its texture, which is mushy but its shape, an umbrella. Mush is an old British slang term for
Theophrastus Bomabastus Von Hoheneheim (Paracelsus) said “sola dosis facet venenum,” translated as, “all things are poisonous and nothing is without poison.” (Wink & Wyk, 2008) For people living in the Great Lakes regions of Northern Michigan, it often feels the opposite, “in everything there is medicine and nothing is without medicine.” Undoubtedly, some plants can externally or internally irritate the body affecting homeostasis, including instances of photo-sensitization and allergies; but generally these symptoms are not life threatening. According to herbalists and toxicologists, it is important to “distinguish between poisons that can kill in minute amounts, toxins that are less toxic than poisons, and toxicants that are toxic in high concentrations only.” (Wink & Wyk, 2008).
