A fungus (pl.: fungi [3] or funguses [4]) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista [5] or Protozoa and Chromista. [6]
There is also a case for a fungal affinity for the enigmatic microfossil Ornatifilum. Since the fungi form a sister group to the animals, the two lineages must have diverged before the first animal lineages, which are known from fossils as early as the Ediacaran. [9] In contrast to plants and animals, the early fossil record of the fungi is meager.
The 1995 edition of the influential Ainsworth and Bisby’s Dictionary of the Fungi sought to replace the term anamorph with mitosporic fungus and teleomorph with meiosporic fungus, based on the idea that the fundamental distinction is whether mitosis or meiosis preceded sporulation. This is a controversial choice because it is not clear that ...
The term dimorphic is commonly used for fungi that can grow both as yeast and filamentous cells, however many of these dimorphic fungi actually can grow in more than these two forms. Dimorphic is thus often used as a general reference for fungi being able to switch between yeast and filamentous cells, but not necessary limiting more shapes. [4] [a]
Because bracket fungi are defined by their growth form rather than phylogeny, the group contains members of multiple clades. Although the term 'bracket fungi' classically was reserved for polypores, molecular studies have revealed some odd relationships. The beefsteak fungus, a well-known bracket fungus, is actually a member of the agarics.
A mycorrhiza (from Ancient Greek μύκης (múkēs) 'fungus' and ῥίζα (rhíza) 'root'; pl. mycorrhizae, mycorrhiza, or mycorrhizas) [1] is a symbiotic association between a fungus and a plant. [2] The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, the plant root system and its surroundings.
Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. [1] Fungi can be a source of tinder, food, traditional medicine, as well as entheogens, poison, and infection.
Some fungi form mushrooms; others grow as single cells and are called microfungi (for example yeasts). A large and taxonomically diverse number of fungal species form molds. The growth of hyphae results in discoloration and a fuzzy appearance, especially on food. [ 3 ]
