Introduction to the Fungi Introduction to the Fungi The Kingdom Fungi includes some of the most important organisms, both in terms of their ecological and economic roles. By breaking down dead organic material, they continue the cycle of nutrients through ecosystems. In addition, most vascular plants could not grow without the symbiotic fungi, or mycorrhizae, that inhabit their roots and supply essential nutrients. Other fungi provide numerous drugs (such as penicillin and other antibiotics), foods like mushrooms, truffles and morels, and the bubbles in bread, champagne, and beer. Fungi also cause a number of plant and animal diseases: in humans, ringworm, athlete's foot, and several more serious diseases are caused by fungi.

Making Spore Prints Making Spore Prints Making Spore Prints by Michael Kuo While a single mushroom spore can't be seen by the naked eye, a pile of many spores can--and the color of a mushroom's spores, seen en masse, is a crucial identification feature. Obtaining a mushroom's "spore print" is therefore an essential step in the identification process. Before going through the nuts and bolts of making a spore print at home, it is worth noting that mushrooms frequently make their own spore prints, in nature. If you have ever noticed colored dust covering a leaf or the ground beneath a mushroom's gills or pores, you have probably witnessed this phenomenon.

Cornell Mushroom Blog Most people don't pay much attention to fungi, which include things like mushrooms, molds, yeasts, and mildews. Here at Cornell we think they're pretty fascinating. In fact, even the most disgusting foot diseases and moldy strawberries are dear to our hearts. Cornell Mushroom Blog
Mushroom Key Mushroom Key Please note that the groupings used in this key do not correspond to taxonomic groups, but to observable characteristics. When you have found the group most like your mushroom, there will be several photos to compare. DO NOT BE SURPRISED if you do not get an exact match; there are over 2000 species of fungi in the Northern Rockies and Pacific northwest, and under 400 photos on our site. You may wish to check with mycoweb or one of the other links listed on this site to find more photos to compare with. Serious students should check out Matchmaker, a program that keys out several hundred species.

Protista Protista Protista Protists are grouped into three major, unofficial categories based on means by which they obtain nutrition. These are the Protozoa, the Algae, and the Fungus-like Protists.
GIANT BLADDER KELP GIANT BLADDER KELP Giant Bladder Kelp (Macrocystis pyrifera) Introduction Giant kelp (Macrocystis pyrifera) is a species of marine alga found along the Pacific coast of North America from central California to Baja California. Although it begins life as a microscopic spore at the ocean floor, this species may grow to lengths of 60 m (200 ft) with its upper fronds forming a dense canopy at the surface.
Introduction to the Bacteria Bacteria are often maligned as the causes of human and animal disease (like this one, Leptospira, which causes serious disease in livestock). However, certain bacteria, the actinomycetes, produce antibiotics such as streptomycin and nocardicin; others live symbiotically in the guts of animals (including humans) or elsewhere in their bodies, or on the roots of certain plants, converting nitrogen into a usable form. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria help to break down dead organic matter; bacteria make up the base of the food web in many environments. Bacteria are of such immense importance because of their extreme flexibility, capacity for rapid growth and reproduction, and great age - the oldest fossils known, nearly 3.5 billion years old, are fossils of bacteria-like organisms.

Introduction to the Archaea Introduction to the Archaea The Domain Archaea wasn't recognized as a major domain of life until quite recently. Until the 20th century, most biologists considered all living things to be classifiable as either a plant or an animal. But in the 1950s and 1960s, most biologists came to the realization that this system failed to accomodate the fungi, protists, and bacteria. By the 1970s, a system of Five Kingdoms had come to be accepted as the model by which all living things could be classified. At a more fundamental level, a distinction was made between the prokaryotic bacteria and the four eukaryotic kingdoms (plants, animals, fungi, & protists).
Extremophiles Are Key, Or Archaea Biology concepts – archaea, bacteria, domains of life, hydrothermal vent ecosystem, chemosynthesis What is a bigger mistake – to overestimate or to underestimate? If you overestimate someone, you may be disappointed with the result. If you underestimate, you may never realize what they are capable of accomplishing. What is more, your underestimation may cause you to miss incredible things already taking place. It would be a mistake to underestimate the grit and power of some of nature’s smallest organisms.
Extremophile Hunter Searches for 'Impossible' Life
Diatoms can be found living in a wide variety of extreme environments, including ancient Antarctic Ice. Some believe they may even exist on Europa and in interstellar dust. The above diatom, Surirella, was collected from the alkaline and hypersaline Mono Lake. Details An extremophile is an organism that thrives under "extreme" conditions. Who Are The Extremophiles?
Archaea There are three main types of archaea: the crenarchaeota (kren-are-key-oh-ta), which are characterized by their ability to tolerate extremes in temperature and acidity. The euryarchaeota (you-ree-are-key-oh-ta), which include methane-producers and salt-lovers; and the korarchaeota (core-are-key-oh-ta), a catch-all group for archaeans about which very little is known. Among these three main types of archaea are some subtypes, which include: Methanogens (meth-an-oh-jins) — archaeans that produce methane gas as a waste product of their "digestion," or process of making energy. Halophiles (hal-oh-files) — those archaeans that live in salty environments.

Virus Structure Virus Structure Viruses are not plants, animals, or bacteria, but they are the quintessential parasites of the living kingdoms. Although they may seem like living organisms because of their prodigious reproductive abilities, viruses are not living organisms in the strict sense of the word.
