2000 Pezizales project presents a catalog of known taxa belonging to the order Pezizales. It provides nomenclatural notes for each taxon, the diagnosis, color pictures and a distribution map. It is a long-term project but we hope that it will be possible to present the 2000 species of Pezizales known in the world (the estimation of Dictionnary of Fungi, in 2008, was 1683 taxa). Be careful, the items presented here do not represent a monographic work.
