It is to Schwendener's knowledge of the facts, the result of researches extending over many years, that the correct interpretation is due in these cases of the relationship borne by the Lichen-forming Fungus to the gonidia, /. e. to the Alga which it attacks1. After these preliminary remarks the following description will be intelligible to the beginner. It is transferred, with but slight alterations, from the first edition of this book

It is to Schwendener's knowledge of the facts, the result of researches extending over many years, that the correct interpretation is due in these cases of the relationship borne by the Lichen-forming Fungus to the gonidia, /. e. to the Alga which it attacks1. After these preliminary remarks the following description will be intelligible to the beginner. It is transferred, with but slight alterations, from the first edition of this book. We will consider first the Lichen as a whole, as it comes under observation, the nourishing Alga being distinguished as an elemental form of the thallus under the name Gonidia; and we will afterwards discuss the question of their algal nature more in detail. The Phallus of Lichens is commonly developed in the form of incrustations which cover stones and the bark of trees, or penetrate between the lamellae of the epidermis of woody plants, and then expose only the fructifications above the surface. These Crus- taceous Lichens, as they are termed, have become so completely united in their growth to their substratum, at least on the under side, that they cannot be detached completely from it without injury to the thallus (Fig. 210, A7B,C). The crustaceous Lichen-thallus.
