How many species?

Little is known about the first fungi to have appeared on Earth; these organisms must have derived from protista. These originated the first fungi, whose fossil finds date back to approximately 400 million years ago.
At present, about 100,000 species of fungi are known, and it is estimated that at least 200,000 are still to be identified.
The evolutionary links between the main classes of zygomycetes, ascomycetes and basidiomycetes are not clear yet, while the class deuteromycetes includes all the species in which no sexed reproduction cycle has ever been observed.
