Abstract

The ultrastructural studies on lichens have been increased during the last years. The freeze-etching technique deals with the possibility of studying ultrastructurally, material coming from lichen thallus without any need that these will be submited to a chemical fixation and to an inclusion on resins. Recently, the technique of freeze-etching has became one of the preparative techniques more important to ultrastructural studies fundamentally to a membrane level. Though, this technique presents a physical method independently to elucidate the ultrastructure of lichen, in this case, this study has been completed with parallel observations by the conventional methods of Transmission Electron Micros- COPY. As the phycobiont's membrane seems to be involved in its totality in the process of transference of metabolites, an special remark on intramembrane particles (IMPs) and on the ridges of the plasmalemma, was made.
