In this paper, mutually recursive function systems, picture-generating devices known in the area of fractal geometry, are translated into TOL collage grammars. The translation works in such a way that the infinite sequence of pictures which is specified by a mutually recursive function system through the Hutchinson operator contains exactly those pictures which belong to the language generated by the corresponding TOL collage grammar. In other words, the translation is correct.
