In 2001, known fungi species totalled around 80,000 worldwide, including close to 2,000 species not classified under Kingdom Fungi: 960 protists (Kingdom Protista) and 889 chromists (Kingdom Chromista). Of these 80,000 species, around 13,500 are lichens. This figure is believed to represent only a tiny fraction of the actual number of fungi species found in the world: estimates put the total at 1.5 million. New species of fungi are discovered every year, and there is clearly much work to be done in the field of mycology, i.e., the study of fungi.
Around 2,100 fungi species (not including lichens) have been found and recorded in Iceland. Information on Icelandic fungi and Kingdom Fungi is divided into 5 main phyla:
1. chytrids (Chytridiomycota)
2. zygote fungi (Zygomycota)
3. glomeromycetes (Glomeromycota)
4. ascomycetes (Ascomycota)
5. basidiomycetes (Basidiomycota)
Anamorphic (mitosporic) fungi reproduce asexually. Most are ascomycetes; a few are basidiomycetes.
