Abstract

The presence of numerous haustoria, with accompanying death of the algal cells, was noted in a mixed cuture of the fungal symbiont (mycobiont) of Collema tenax (Sw.) Ach., em. Degel. and Trebouxia impressa Ahm., the algal partner (phycobiont) of Physcia stellaris (L.) Nyl. The parasitic action was noted even on media which would optimally sustain the independent growth of the individual symbionts.
