The author has studied these fascinating fungi for decades and has published widely on the subject, including new taxa. Furthermore, in collaboration with Ellen Larsson (GB), the phylogeny has been studied based on DNA-sequences. This has led to a new understanding of the genus, and has led to segregation of new species and genera. The volume covers all psathyrelloid taxa irrespective of their current classification except species of Lacrymaria.
Leif Örstadius resides in Kristianstad in Southern Sweden. He has a special fondness for the steppe-like landscape near his home, where he has studied not least the coprophilous species of the Psathyrellaceae.
