Fungi (kingdom)

Kingdom containing around 80,000 known species of non-photosynthetic organisms composed of one or more cells having visibly evident nuclei. They obtain nutrients by the absorption of organic compounds from their surroundings, bear spores, and typically reproduce both sexually and asexually, including yeasts, rusts, smuts, mildews, molds, mushrooms, and toadstools. The term "fungi" is also used erroneously for organisms that superficially look like true fungi, including slime molds and oomycetes that do not actually belong to the kingdom Fungi.
