4-8 cm. long, 8-12 mm. thick, equal to slightly enlarged at base, 

 white and silky with the white veil, tinged violaceous within." 

 SPORES elliptical, rough, obtuse at ends, 9-12x5.5-6.5 micr. 



"Grassy ground in open places, thin woods. New York. 

 September. A rather large and stout plant, remarkable for the 

 tendency of the epidermis to crack in areas. The thin margin is 

 often split."' Peck considered it to be near G. caninus Fr. and C.

 group. It must be remembered that other species often have a 

 rimose pileus under certain weather conditions.
