FRULLANIA. 



F. Eeoracensis Gottsche, Any one who has been in the 

 woods at all must have noticed the pretty designs in dark brown- 

 ish-green on the bark of beeches and birches like those in the 

 figure. So common and so striking is this little plant that almost 

 no further description is needed for its identification. Although 

 it is so tiny, its underleaves and lobules can be made out easily 

 with a hand-lens if a specimen be mounted in water on a micro- 

 scopic slide.
