21. — Pruit of Puccinia graminis germiuatiiig and producing globose "spo- 

 ridia." 



22. — ^Truit of Puccinia Lychnidearwm, germinating (magnified 315 diameters). 



23. -Peculiar germination observed in Triphrac/mium JJlmarice. (The figure 

 only shows a portion of the germ-filament, magnified 420 diameters.) 



24. — A joint of the above filament of Triphragmium Ulmarice which has 

 separated itself and commenced germination. 



25 to 33. — Various forms of fruit of Phragmidium Potentilla. 



34. — Pruit of Xenodochus carbotmmts. 



35, 36, 37. — Spores of a species of Gymnosporium in germination. 



38. — Spores of Pezizaaurantia, exhibiting the peculiar germination referred 

 to in the text. 



39. — Spores of Peziza aurantia in their ordinary state. 



40. — Spore of a species of Triposporium. 



41. — Filament of Zygodesmus fuscus, showing the sterigmata at the apex. 

 On the right hand are three spores detached. 



42. — A fragment of the capillitium of Trichia turhinata acted on by hydro- 

 chloric acid, showing the mode of spiral unrolling of the membrane 

 and the five internal bands (highly magnified, but to no particular 

 scale). 



43. — Two specimens of a doubtful Trichia (slightly magnified). 



44. — A portion of the capillitium and some spores of the last-mentioned 

 plants.
