Mycologia 



decaying vegetable matter in Yucatan by Millspaugh in 1895. 

 Ellis remarked that it had the appearance of a Lepiota but that 

 the spores were brown. A microscopic examination of the type 

 shows the spores to be ovoid, smooth, slightly obliquely apiculate 

 at the base, hyaline with a distinctly melleous tint, granular, 

 9X5^ This agrees very well with the characters of the spores 

 of Lepiota cretacea, except for color, while in general appear- 

 ance the two species are not very distinct. It is well known that 

 some species of Lepiota have darkened spores. 



13. Coprinus Pers. Tent. Disp. Fung. 62. 1797 



This genus is readily distinguished among the black-spored 

 gill-fungi by its deliquescing lamellae. As at present constituted, 

 it includes a large and heterogeneous group of species, which fall 

 naturally into three or more groups. Professor Earle has col- 

 lected a large number of specimens in Cuba, most of them of the 

 general type of C. plicatilis and C. Spraguei, representing the 

 genus Coprinopsis of Karsten, a segregate of Coprinus, which 

 dry more readily than the more fleshy species usually found by 

 collectors. 



No atttempt will be made now to segregate the genus nor to 

 study fully the material at hand. This will be left for Professor 

 Pennington, who has undertaken to monograph the genus for 

 North American Flora. 



Pileus entirely white; stipe 2.5-4 cm. long 1. C. cubensis. 



Pileus whitish, but differently colored on the disk; stipe 

 5-8 cm. long. 



Disk fulvous 2. C. fimetarius. 



Disk cinereous 3- C. armillaris. 



Pileus pale-yellowish-white, somewhat darker on the disk ; 



stipe only 2 cm. long 4. C. jalapensis. 



Pileus rose-colored, very small 5. C. mexicanus. 



Pileus griseous, murinous, or fuliginous. 



Stipe 1 cm. long 6. C. jamaicensis. 



Stipe 3-4 cm. long 7. C. cinchonensis. 



Stipe 5-7 cm. long 8. C. Spraguei.
