esting fashion which merits well the term " shaggy." In others the 

 threads are looped up quite regularly into triangular tresses which 

 appear to be knotted at the ends where the tangle of brown threads 

 holds them together. 



There is one curious feature about the expansion of the pileus of 

 the shaggy-mane which could not escape our attention. The pileus 



has become very 

 long while compar- 

 atively little lateral 

 expansion has 

 taken place. The 

 pileus has remained 

 cylindrical or bar- 

 rel-shaped, while in 

 the case of the com- 

 mon mushroom the 

 pileus expands into 

 the form of an um- 

 brella. 



The cylindrical 

 or barrel -shaped 

 pileus is character- 

 istic of the shaggy- 

 mane mushroom. 

 As the pileus elong- 

 ates the stem does 

 also, but more 

 rapidly. This tears 

 apart the connec- 

 tion of the margin 

 of the pileus with 

 the base of the 

 stem, as is plainly 

 shown in Fig. 33. 

 In breaking away, 

 the connecting por- 

 tion or veil is freed 

 both from the stem 

 and from the margin 

 of the pileus, and is 

 left as a free, or 

 loose, ring around
