A new alternative method using perlite as a particulate solid carrier in the growth medium with a cryoprotectant was successfully tested for cryopreservation of several basidiomycete species from different genera (Armillaria, Pleurotus, Pluteus, Polyporus) which failed to survive or retain their properties in cryopreservation procedures routinely used in our laboratory. Frozen basidiomycete strains were kept in cryovials submerged in liquid nitrogen and were either immediately after the freezing process or after a 6-month storage thawed and checked for viability, purity and changes in growth, morphology and biochemical characteristics. All cultures survived the cryopreservation procedure and no negative effects of cryopreservation by this method have been observed after 6 months of storage in liquid nitrogen.
