Although there are over 50,000 identified species of fungi, only a few hundred are known to be pathogenic, causing infections known as '''mycoses''' (mycology being the study of fungi). Fungi are nonphotosynthetic organisms (lack chlorophyll) which are restricted to a parasitic or saphrophytic exsistence. They are abundant in soil, vegetation, water and on decaying vegetation and wood. Fungi have a eukaryotic cell structure and are able to grow as branching or filamentous forms (mycelia) or as single cells (yeasts).
