PLATE 54 



Fig. 1. Part of a typical vegetative hypha to show the structural charac- 

 ters. Clamp connections are shown at each septum. The nuclei are near the 

 center of each cell. 1500 diameters. 



Fig. 2. Portion of a vegetative hypha covered with lateral projections. 

 1500 diameters. 



Fig. 3. Hyphae which form the hairy covering of the pileus. They are 

 usually unicellular, the nuclei being near the base of the cell. In this drawing 

 a portion of each cell 1.4 mm. long was left out. This would represent a distance 

 of about 210 cm. on the drawing paper. 1500 diameters. 



Fig. 4. Portion of a longitudinal section through the flesh of a very young 

 sporophore to show the hyphal structure. 1500 diameters. 



Pig. 5. Same as in fig. 4, except that the section was taken from an old 

 sporophore. 1500 diameters. 



Fig. 6. Portion of the hymenium, showing one mature and one immature 

 basidium. 1500 diameters. 



Fig. 7. Six typical spores, stained in safranin and gentian violet to show 

 the nuclei. 2500 diameters. 



Fig. 8. Germinating spores in various stages of development after being 

 in distilled water for 48 hours. Stained in safranin. 1500 diameters.
