FORMS OF CYATHUS VERNICOSUS. 



The plant is quite variable in the size and shape of the cups and to a 

 degree the color. Tulasne distinguishes four varieties which I have not found 

 practicable to distinguish. From England I have a collection with cups very 

 much like Cyathus stercoreus in general appearance, which is the only collec- 

 tion I have seen that could well be confused with that species. From Rev. H. 

 Bourdot, France, I have a collection whiter in color and with softer hairs than 

 usual. 



CYATHUS DASYPUS. Nees von Esenbeck illustrates a plant from 

 South Africa under the above name, which seems both from his description and 

 figure to be the ordinarv form of Cyathus vernicosus. Tulasne has applied the 

 name to a plant from Chile, agreeing with Cyathus vernicosus, excepting it has 

 more irregular peridioles. I hardly think it merits a name even as a variety, 

 but if it does I see no harm in applying Cyathus dasypus to it in the sense of 

 Tulasne, though there is nothing in the original to indicate that the peridioles 

 are irregular. 



CYATHUS ANGLICUS (Fig. 17, en- 

 larged 4 times). At Kew I noted several 

 collections of Cyathus vernicosus, made in 

 England, with large, silicate cups. While 

 the cups might well be described as striate, 

 they have no relation to the section Eu- 

 cyathus. I think this form is solely Eng- 

 lish, for I have seen no specimens from 

 any other locality. The plant Miss White 

 illustrates from Colorado under the name 

 Cyathus dura seems to me very much the 

 same nature.
