A life among polypores
Leif's passion for polypores started with an accidental collection of a bracket fungi which then developed to a lifestyle. In the course of collecting polypores for the last 40 years Leif has visited over 70 different countries, resulting in 50,000+ collections in the Oslo Fungarium. Twelve African PhD students have stayed in Oslo under Leif's supervision, which in turn resulted in numerous expeditions and field work in all types of tropical forests as well as other remote places where no collections have been made, such as Tierra Fuego and St. Helena, to mention a few.
