Mycologia 



This genus includes species with adnate or adnexed lamellae 

 and cartilaginous stipe, the margin of the pileus being incurved 

 when young instead of straight as in Nolanea. The plants are 

 usually small, with attractive blue, gray, or purple coloring. 

 Only two species have been previously described from our tropics. 



I. Leptoniella hypoporphyra (Berk. & Curt.) 

 Agaricus {Leptonia) hypoporphyrus Berk. & Curt. Jour. Linn. 

 Soc. 10 : 289. 1868. 



Described from Wright's Cuban collections and found later in 

 Guadeloupe by Duss. The spores are angular, 7-9 /x. The types 

 at Kew are in poor condition. 



2. Leptoniella miniata (Pat.) 

 Leptonia miniata Pat. Bull. Soc. Myc. Fr. 16: 176. 1900. 



Collected on dead trunks of various trees in Guadeloupe by 

 Duss. Pileus red, striate; spores angular, 10-13 //,. Abundantly 

 represented in Dr. Patouillard's herbarium. 



3. Leptoniella atrosquamosa sp. nov. 



Pileus broadly convex, slightly depressed, regular, solitary, 2 

 cm. broad ; surface avellaneous, striate, clothed with innate, im- 

 bricate, fuliginous scales which are upturned at the end, the de- 

 pressed umbo being decorated with black tufted scales ; lamellae 

 adnate, narrow, distant, about three times inserted, edges entire, 

 concolorous ; spores angular, 8-10 fx; stipe cylindric, equal, muri- 

 nous, 3.5 cm. long, 2-3 mm. thick. 



Type collected on dead wood at Morce's Gap, Jamaica, 5000 

 ft. elevation, December 30, 1908, W . A. & Edna L. Murrill 708. 

 Resembling L. serrnlata in general appearance. 



4. Leptoniella Earlei sp. nov. 



Pileus convex, umbilicate, thin, solitary, 2 cm. broad ; surface 

 pale-tan, subfurfuraceous, the disk scaly, margin thin, not striate ; 

 lamellae adnexed, distant, broad, dirty-pink, heterophyllous ; 

 spores angular, irregular, 10-13 X7-8 /a; stipe cylindric, gla- 

 brous, subpruinose above, slightly paler than the pileus, hollow, 

 4 cm. long, 2 mm. thick. 



Type collected on the ground in woods on El Yunque, Cuba, 

 1800 ft., March, 1903, Underwood & Earle 4.27 :
