Summary
An investigation was made of the vegetative thallus of the lichen Peltigera polydactyla. Using a modified embedding technique it was shown that the ultrastructure of the mycobiont was not radically different from that of nonlichenized Discomycetes, and that the ultrastructure of the phycobiont was like that of the blue-green alga Nostoc. In addition to what were considered healthy blue-green algal cells other cells were present which obviously were breaking down. Well defined heterocysts were also present. No haustoria were found in the thallus.
