1887. 



This species, originally described from Sprague's collections in 

 New England and known to occur from Canada to Alabama and 

 west to Wisconsin, is peculiar in having aborted sporophores 

 more frequently than normally developed ones. These irregu- 

 larly globose abortions, distantly resembling puff-balls, were found 

 in the market at Jalapa, having been collected in the surrounding 

 forests by the Indians for food.

2. Pleuropus Earlei sp. nov. 



Pileus thin, firm, convex to subexpanded, umbilicate, gregari- 

 ous, 1-2 cm. broad; surface pure-white, glabrous, margin entire, 

 inrolled when young; lamellae short-decurrent, subcrowded, nar- 

 row, irregular, pure-white to pink ; spores angular, 7 X 5-6 ^ ; 

 stipe short, subequal, often flattened, pure-white, fistulose, 

 minutely pruinose to glabrous, surrounded at the base with 

 whitish mycelium, 2-3 cm. long, 2-3 mm. thick. 



Collected on the ground in a banana field at Santiago de las 

 Vegas, Cuba, from May to September, 1904, F. S. Earle 31 

 {type), 70, 179. The fresh specimens have a strong odor of 

 wild onions. 



7. Volvariopsis nom. nov. 

 Volvarius Roussel, Fl. Calvados ed. 2. 59. 1806. Volvaria 

 (Fries) Gillet, Champ. Fr. 1: 385. 1878. Not Volvaria DC. 

 1805. 



The type of this genus is Volvaria volvacca (Bull.) Quel. The 

 species are largely temperate, and form a natural group with 

 distinctive characters, corresponding to Amanitopsis in the white- 

 spored series. Only one species, V. bombycina, has heretofore 

 been reported from tropical America. Locellina hiatuloides Pat., 

 described from Guadeloupe, has the form and appearance of a 

 species of this genus, but the spores are ochraceous. It is just 

 possible that their color has become changed in drying.
