 the largest fully matured. Fig. B shows a small portion cut vertically from the hyme'- 

 nium, or layer of as'ci, and paraph'yses, slightly magnified. I'ig. C illustrates stages 

 in spore-formation in the as'cus. Fig. D represents a ripe as'cus containing the mature 

 spores, accompanied by a paraph'ysis; magnified 6(10 diameters. I'ig. E shows a ripe 

 spore with its jiromintnt sjiines, magnified IrJ(M) diameters. Fig. F is a portion of the 

 myce'lium from the soil; magnified 1000 diameters. These figures were drawn by Mr.
