The monokaryotic yeast phase of the heterobasidiomycete Itersonilia perplexans , unlike the hyphal phase, was found to be sensitive to mycocins produced by killer strains of Cryptococcus humicola, Cr. laurentii, Cystofilobasidium bisporidii and Rhodotorula fujisanense . Both the yeast and hyphal phases were resistant to mycocins of Cr. podzolicus, Filobasidium capsuligenum, Rhodotorula glutinis, Rh. mucilaginosa, Rh. pallida, Sporidiobolus johnsonii, Sb. pararoseus and Sporobolomyces alborubescens . The different sensitivity patterns of yeast and hyphal phases are probably caused by biochemical differences in the cell walls.
