Abstract
An unidentified basidiomycete was found capable of parasitizing 37 of 50 isolates of fungi tested as hosts. All phytopathogenic fungi tested, as well as most of the saprophytic fungi, were susceptible to this mycoparasite. In some cases, reproductive structures as well as hyphae were infected. High glucose-yeast extract ratios in the test medium favored parasitism. The mycoparasite was able to utilize 14 of 27 compounds tested as carbon sources.
