Penicillium is a fungi that is the chief culprit of food spoilage. Many penicillium have a bluish color to them, resulting in a fuzzy, blue appearance, such as that found in common bread mold. Penicillin is an antibiotic that is derived from the fungus penicillium. Penicillin is an antibiotic that is useful in fighting bacterial infections. Coprinus is another fungi, a small genus of mushrooms, that have a large, dome shaped cap. These domes can have a "shaggy" appearance,as they droop down the exterior of the cap. The lavellae of the coprinus mushroom are autodigested to release their spores, resulting in an inky black liquid. Coprinus is sometimes called an "ink cap" because of this. The name coprinus means "living on dung" fungi. The candida albicans is a diploid fungus that is common in the human mouth and gut. It is instrumental in helping some aspects of digestion, but can morph into a more dangerous form of fungi. A noted rise in candida frequency occurs with people who have tongue piercings than with people who do not.
