], 2. Lentinus lepideus. Fig. 1. — A much - branched

 stipes springing from its margin ; s s , tertiary stipe. 

 Fig. 2. — A forked individual growing under similar 

 conditions. (After Buller.) p. 16.

 (After De Seynes.) p. 23. 

 10. Coprinus stercorarius. Four generations (1-4) of 

 " fructifications " formed as the result of excising 

 the pileus at every stage of growth. Adventitious 

 mycelium formed at regions of excision. (After
