2. Nolanea cubensis sp. nov. 



Pileus thin, convex to subexpanded, subumbonate, 2-3 cm. 

 broad; surface pale-fuscous, minutely silky-fibrillose, at length 

 rimose, striate to the umbo ; lamellae free, crowded, rather broad, 

 ventricose, white to pale-roseous ; spores subglobose, smooth, 6 [x ; 

 cystidia none ; stipe cylindric, solid, white, glabrous above, brown- 

 ish-flocculose at the base, 3 cm. long, 2 mm. thick. 



Type collected on a piece of board on the ground in a coffee

3. Nolanea jamaicensis sp. nov. 



Pileus campanulate with conic umbo, about 4 cm. broad ; sur- 

 face striate, glabrous, avellaneous, umbrinous to fuliginous at the 

 umbo, margin entire, concolorous ; lamellae rather broad, close, 

 adnexed, salmon-colored from the copious spores, which are 

 angular, somewhat longer than broad, 9-1 1 X 7~9 ^ ', stipe cylin- 

 dric, equal, smooth, glabrous, pale-avellaneous, 6 cm. long, 3 mm.

4. Pluteus Fries, Gen. Hymen. 6. 1836 

 This genus is best known through its large and common repre- 

 sentative, P. cervinus. The lamellae are free, the stipe fleshy 

 or fibrous, and most of the species are found on decayed wood. 

 The spore characters are similar throughout the genus. Cystidia 

 3ccur rarely, and in one species they are peculiar in having the 

 apex divided into two or more points. 



1. Pluteus cervinus (Schaeff.) Quel. Champ. Jura Vosg. 81. 



1872 



Abundant in various forms throughout the United States and 

 Europe on decayed wood and sawdust piles. Spores ellipsoid, 

 smooth, 7-8 X5~6jti; cystidia bottle-shaped, large and conspic- 

 uous, divided at the apex into two, three, or more points. The 

 tropical stations given below are all at 5000 ft. elevation.
