Structural modifications of the phycobiont in the lichen thallus

Summary

Modifications in the fine structure of the algal component of two lichens,Aspicilia sp. andSquamarina crassa v.crassa, have been studied. It has been pointed out that fungal penetration is not essential for the mutual relationship between the two symbionts of the lichen thallus. The structural changes taking place during the life cycle of the phycobiont of the two lichens examined are not a response to fungal invasion.

Careful examinations of serial sections revealed an interesting correlation between the growth pattern of the thallus and the distribution of the algal cells in the algal layer.
