2. With the forceps tear away some of the white fila- 

 ments of the outer ring. Mount them in 30 per cent 

 alcohol and examine under high power. What is the 

 shape of the distal end? Do these white filaments bear 

 gonidia? Are there septa across the filaments? Treat 

 with Schultze's solution. Are the cell walls composed of 

 ordinary or of fungous cellulose?
