evolution of fungi









































the evolution of fungi has been going on since fungi diverged from other life around 1.5 billion years ago, (wang et al., 1999) with the glomaleans branching from the "higher fungi" at ~, according to dna analysis. (schüssler et al., 2001; tehler et al., 2000) fungi probably colonized the land during the cambrian, over , (taylor & osborn, 1996) but terrestrial fossils only become uncontroversial and common during the devonian, .

evolution of fungi
the non-lichenised species come from 416 different genera, representing all major fungi phyla. the first fungi identified from the sub-antarctic islands was "peziza kerguelensis", which was described in 1847. in 1898 the first species from the mainland, "sclerotium antarcticum", was sampled. far more terrestrial species have been identified than marine species. larger species are restricted to the sub-antarctic islands and the antarctic peninsula. parasitic species have been found in ecological situations different from the one they are associated with elsewhere, such as infecting a different type of host. less than 2-3% of species are thought to be endemic. many species are shared with areas of the arctic. most fungi are thought to have arrived in antarctica via airborne currents or birds. the genus "thelebolus" for example, arrived on birds some times ago, but have since evolved local strains. of the non-lichenised species of fungi and closer relatives of fungi discovered, 63% are ascomycota, 23% are basidiomycota, 5% are zygomycota, and 3% are chytridiomycota. the myxomycota and oomycota make up 1% each, although they are not true fungi.
