Other recent studies (2009) estimate the arrival of fungal organisms at about 760–1060 Ma on the basis of comparisons of the rate of evolution in closely related groups. [13] For much of the Paleozoic Era (542–251 Ma), the fungi appear to have been aquatic and consisted of organisms similar to the extant Chytrids in having flagellum-bearing ...
Mycorrhizal relationships between plant and fungi are mutualistic: the fungus gains a carbon source, while the plant receives nutrient minerals. Discovery of fungi in the Early Devonian Rhynie chert, when plants were root and leafless, suggests that fungi played a large role in the evolution of plant life into terrestrial ecosystems. [3]
Eukaryogenesis, the process which created the eukaryotic cell and lineage, is a milestone in the evolution of life, since eukaryotes include all complex cells and almost all multicellular organisms. The process is widely agreed to have involved symbiogenesis , in which an archeon and a bacterium came together to create the first eukaryotic ...
The Fungi are classified as a kingdom that is separate from plants and animals. The discipline of biology devoted to the study of fungi is known as mycology or fungal biology, which is historically regarded as a branch of botany, even though genetic
The English word fungus is directly adopted from the Latin fungus (mushroom), used in the writings of Horace and Pliny. [10] This in turn is derived from the Greek word sphongos (σφόγγος 'sponge'), which refers to the macroscopic structures and morphology of mushrooms and molds; [11] the root is also used in other languages, such as the German Schwamm ('sponge') and Schimmel ('mold').
The comparison of fungal genomes has been used to study the evolution of fungi, to improve the resolution of the phylogeny of fungal species, and to determine the time of the emergence and changes in species traits and lifestyles, such as the evolution symbiotic or pathogenic interactions, and the evolution of different morphologies.

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.
It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. [3] Within the subdivision Agaricomycotina , which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes , which ...
