white, unless by some accident the plant becomes old before the veil 

 breaks. The cap now expands more and more, and the veil is ruptured, 

 as shown in figures 93 and 94. In both of these photographs the frag- 

 ments of the veil are shown clinging partly to the stem and partly to 

 the margin of the pileus, where the dripping tender fibrils lend a weird 

 aspect to the spectre-like plant as it lifts its head from the sod at night. 

 Because of the very delicate and fragile character of the veil, it 

 does not in many cases remain clinging to the stem as a complete 

 ring, and it is also in some cases quite evanescent. In figure 87 the

ring is well formed. In figure 94, where the photograph was taken 

 soon after the rupture of the veil, the edge of the ring has a tendency 

 to be double where the threads break away from the inner and outer 

 edges of the cap. In some other mushrooms this double character of 

 the ring is quite pronounced, but here it is quite rare. 



Sometimes the fibrils on the surface of the pileus are drawn into 

 triangular patches which point outward, as shown in figure 95. This 

 gives a scaly appearance to the surface of the pileus. While in the 

 ordinary form of this musliro ):n the surface of the cap is white, often
