The Collection of Microscopic Fungi of the Institute of Soil Biology BC CAS (CMF-ISB), is a nonprofit organization established in the Laboratory of Soil Biology, Institute of Landscape Ecology CSAS in 1980 by RNDr. Alena Nováková, Ph.D.
In 1990, the CMF-ISB was enriched by strains of ovicidal microfungi from the collection of Prof. MUDr. Hynek Lýsek, Dr.Sc. (Palacký University, Olomouc).
Since 1993, the CMF-ISB is a member of the Federation of Czech and Slovak Culture Collections of Microorganisms (FCCM).
The CMF-ISB became a member of the Biology Centre Collection of Organisms (BCCO) in 2015.
Currently, the CMF-ISB is hosted by the Laboratory of Mycology at the Institute of Soil Biology BC CAS.
The main function of the CMF-ISB is to collect, maintain and supply cultures of microscopic fungi, and to provide information on microscopic fungi by publishing a catalogue of strains. The cultures are used for basic and applied research, pharmaceutical and food industry, agriculture, medicine, education and general scientific interest.
