Lichens. 



Growth-Forms of Lichens.* — Max Britzelmayer has made a study 

 of several forms of Gladonia. He finds that in many cases varieties 

 that have been described as such are merely due to accidents of habitat. 

 He traces the different growths of V. furcata, which grows best on chalk 

 or loamy sandy soil. In less favourable localities it is found as vars. 

 subulata and tenella with a much more slender growth ; in damp woods 

 the form regalis is found with well-developed podetia and no thallus. 

 He notes also changes of colour due to locality in this and other 

 CJadonuB : brown moor-inhabiting forms change to light green in damp 

 shady woods. 



Development of Lichen Fruits.j — Otto Metzger selects several 

 types of Lichens that have not yet been properly worked out in order to 

 further our knowledge of this subject. In all the cases examined he
