The numbers of fungi: contributions from traditional taxonomic studies and challenges of metabarcoding

Abstract The global diversity of fungi has been estimated using several different approaches. There is somewhere between 2–11 million species, but the number formally described taxa around 150,000, a tiny fraction total. In this paper, we examine 12 ascomycete genera as case studies to establish trends in fungal species descriptions, and introduce new each genus. To highlight importance traditional morpho-molecular methods publishing novel that are considered have low discovery. We discuss whether likely be rare or due lack extensive sampling classification.
