Fig. 58. — Fimetaria fimicola. Perithecia developing on nutrient agar in a Petri 

 dish in a cupboard with a glass door (same culture as that shown in Fig. 57). 

 Light directed from left to right. The beaks of the perithecia are posi- 

 tively heliotropic and, in consequence, the asci of the older perithecia have 

 shot their spores toward the source of the light. A thick black spore- 

 deposit can be seen on the side of the Petri dish and on the surface of the 

 agar. Photographed by H. T. Giissow at Ottawa. Magnification, about 10.

Several other hanging-drop cultures of the mycelium of F. 

 fimicola were made and in all of them protoplasmic streaming was
