Abstract

IN a paper on the constitution of cell walls of fungi, R. Frey1 concludes that several fungi and algae show in their cell contents or membranes an inorganic substance with an X-ray diagram corresponding to that of barium sulphate. Since, in our researches on. cell-walls of fungi2,3, X-ray interferences suggesting the presence of that substance were never observed, some further work was done in order to check Frey's statements.
