Ahmadjian V. & Jacobs J.B. (1987): Studies on the development of synthetic lichens, Bibliotheca Lichenologica, 25: 47-58

SEM studies of fibrils formed from the synthesis of Usnea strigosa mycobiont with the photobiont Trebouxia erici revealed similarities with the natural lichen in terms of morphology and secondary compounds even though the extent of lichenization with the foreign alga was much less. Synthetic forms of an Antarctic cryptoendolithic lichen, which in its natural state does not form a thallus, showed the beginnings of thallus formation. We suggest that the endolithic lichen is a modification of an epilithic … Read more...

Poelt J. (1987): On reductions of morphological structures in lichens, Bibl. Lichenol., 25: 35-45

Reductions have played an important role in the evolution of lichens as in other groups of organisms. They are correlated with adaptations in changing ecological conditions. Several examples are discussed: Reduction of rhizines and rhizinomorphs, of the lower cortex, and of thalli in parasitical lichens. Furthermore, reductions of excipular structures in aspicilioid groups are described. Lecideine structure may also be seen as a reduction. Even paraphyses and apical apparati may be reduced in connection … Read more...
