CIVIC BIOLOGY 



8. Stinkhorns, mushrooms which, once snielled, can never be mistaken 

 for anything else or forgotten. The immature plants, known appropri- 

 ately as witches'-eggs, resemble puffballs externally ; but as one matures, 

 out shoots a long, hollow stem bearing pendent from the tip a small 

 pileus, and this carries the spores in reticulations of its outer surface 

 Phalloidece. 



9. -Trembling mushrooms : soft, gelatinous fungi (witches'-butter) in 

 color varying from white to orange, red, or brown, generally found grow- 

 ing on wood or parasitic on other fungi Tremellaceix. 



The first purpose of these lessons should be to learn to 

 recognize the deadly genus Amanita. Then let each student 

 acquaint himself with as many as possible of the abundant 

 edible mushrooms. An excellent plan is to have the class 

 unite in making a neat card catalogue of the most abundant 

 and valuable mushrooms found growing in the locality this 

 catalogue to be left in the laboratory as part of its biological 

 equipment during the year. A sample card might read about 

 as follows :
