 gemmate warts originating from the cracking of the epidermis, 

 causing it to resemble the skin of a crocodile ; lamellae broad, 

 ventricose, crowded, narrowed behind; spores ellipsoid, obliquely 

 pointed at the base, smooth, uniguttulate, dark purplish-brown, 

 11-13 X 6-7 />t; stipe short, white, smooth, glabrous, 12 X 6 cm., 

 very much inflated at the center, where it reaches 9 cm. or more 

 thick; veil superior, white, membranous. (pL 77.)

 under a microscope. The spores of both species are immense and 

 vary considerably in size.
