A fungus (/ˈfʌŋɡəs/; plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds, as well as multicellular fungi that produce familiar fruiting forms known as mushrooms. These organisms are classified as a kingdom, Fungi, which is separate from the other life kingdoms of plants, animals, protists, and bacteria.
One difference that places fungi in a different kingdom is that its cell walls contain chitin, unlike the cell walls of plants, bacteria and some protists. Similar to animals, fungi are heterotrophs, that is, they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Growth is their means of mobility, except for spores, which may travel through the air or water (a few of which are flagellated). Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the Eumycota (true fungi or Eumycetes), that share a common ancestor (is a monophyletic group). This fungal group is distinct from the structurally similar myxomycetes (slime molds) and oomycetes (water molds). The discipline of biology devoted to the study of fungi is known as mycology (from the Greek μύκης, mukēs, meaning "fungus"). In the past, mycology was regarded as a branch of botany; today it is a separate kingdom in biological taxonomy. Fungi are genetically more closely related to animals than to plants.
Planet Earth may refer to Earth, the third planet from the sun.
Planet Earth may also refer to:
North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea.
North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 16.5% of the earth's land area and about 4.8% of its total surface. North America is the third largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe.
In 2013, its population was estimated at nearly 565 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands (most notably the Caribbean) are included.
North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago (the beginning of the Archaic or Meso-Indian period). The Classic stage spans roughly the 6th to 13th centuries. The Pre-Columbian era ended with the arrival of European settlers during the Age of Discovery and the Early Modern period. Present-day cultural and ethnic patterns reflect different kind of interactions between European colonists, indigenous peoples, African slaves and their descendants. European influences are strongest in the northern parts of the continent while indigenous and African influences are relatively stronger in the south. Because of the history of colonialism, most North Americans speak English, Spanish or French and societies and states commonly reflect Western traditions.
Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in the global food web. Fungi, which thrive on death, make all life possible.

Life on Earth 008 - Fungi Paul Andersen surveys the Kingdom Fungi. He starts with a brief description of the fungi phylogeny. He describes some of the major characteristics of fungi; heterotrophy, cell walls of chitin, hyphae, sessile. He describes the characteristics of five major phyla of fungi, ascomycota, basidiomycota, chytridiomycota, glomeromycota and zygomycota.

The Bitter Oyster Mushroom This mushroom is found in the local regions of North America, Europe, Asia, and Australia where it grows in clusters located mostly on oak, birch, and beech trees. Bitter oysters happen to be one of the manly bioluminescent mushrooms that exist and it’s only the eastern North American strain that is able to glow, unlike the Pacific strain. It’s thanks to this species of mushroom that the term foxfire was coined by the early settlers. Fun fact: This mushroom is classified as being bioremediation as it has the power to absorb the toxins from environmental pollutants and is ab...
Molds are a large and taxonomically diverse number of fungal species where the growth of hyphae results in discoloration and a fuzzy appearance, especially on food. The network of these tubular branching hyphae, called a mycelium, is considered a single organism. The hyphae are generally transparent, so the mycelium appears like very fine, fluffy white threads over the surface. Cross-walls (septa) may delimit connected compartments along the hyphae, each containing one or multiple, genetically identical nuclei. The dusty texture of many molds is caused by profuse production of asexual spores (conidia) formed by differentiation at the ends of hyphae. The mode of formation and shape of these spores is traditionally used to classify molds. Many of these spores are colored, making the fungus m...

Fungi are a biologically important, and often overlooked Kingdom of organisms. In this Naked Science Scrapbook we find out what a fungus actually is, how they live and how they cause and fight disease. Plus we see that many of our favourite meals wouldn't be the same without them.More videos and podcasts from http://www.thenakedscientists.com

The fungi–including various mushrooms, molds, and yeasts–are critical players in the forest ecosystem. This video set explores the various roles of fungi as parasites, decomposers, and cooperative partners with trees, and feature the research of Harvard scientist Anne Pringle.

Enter the magical miniature world of fungi in these time-lapses by fungi photographer Stephen Axford. Two photographers, Steve Axford and Catherine Marciniak, only one intervalometer and a forecast of a stormy Sunday afternoon resulted in the story of a forest to go with the fabulous time-lapse photography Steve has been doing of fungi growing. Some of the fungi in this video are luminous fungi, Mycena chlorophos, the spikey fungi is an un-named new species and the video also features Coprinus disseminatus and a yellow fungi which needs some more research. There are also cameo performances by a trapdoor spider and a miniature slime mould. The music for this video is "Minor Madness" by davej. We discovered this great didgeridoo track on triplej Unearthed and davej has generously allowed...
