Antagonistic effects of Dacrymyces stillatus against growth of other fungi

IRG/WP 2363

J Bjurman

The antagonistic effects in dual cultures on malt extract agar of 5 wood decay fungi and the antagonistic effects of Dacrymyces stillatus against 1 mould fungus and 1 blue stain fungus were determined. Dacrymyces stillatus was the only fungus which exhibited clear antagonistic effects. The effects of Dacrymyces stillatus against the different test fungi varied however to a great extent. Dacrymyces stillatus exhibited clear antagonism against brown rot fungi and a weaker effect against a mould fungus and a blue stain fungus. The antagonistic effect against a white rot fungus was weaker in dual culture. Spore germination of the responding white rot fungus Pycnoporus cinnabarinus was completely inhibited on an agar overlay over a culture of Dacrymyces stillatus on malt extract agar. Inhibitory activity was present in extracts.
