2. Lentinula Earle, Bull. N. Y. Bot. Gard. 5: 416. 1909 

 In this genus, the lamellae are aclnate and the context rather 

 thick and firm. 



Lentinula detonsa (Fries) 

 Lentinus detonsus Fries, Nova Symb. 38. 185 1. (Type from 

 Costa Rica.) 



Lentinus cubensis Berk. & Curt. Jour. Linn. Soc. 10: 302. 1868. 



(Type from Cuba.) 

 Lentinus proximus Berk. & Curt. Jour. Linn. Soc. 10 : 302. 1868. 



(Type from Cuba.) 

 Lentinula cubensis Earle, Bull. N. Y. Bot. Gard. 5: 417. 1909. 



This species occurs on dead wood in many parts of the West 

 Indies, and also in Costa Rica and Louisiana. The gills are 

 separated from the stipe in all the specimens I have seen, as 

 though torn away by contraction on drying.

3. Lentinus Fries, Syst. Orb. Veg. 77. 1825 

 Panus Fries, Epicr. Myc. 396. 1838. 



Pocillaria (P. Browne) O. Kuntze, Rev. Gen. 2: 865. 1891. 



The fact that the type of the genus Lentinus (L. tuber-regium 

 Fries) produces its sporophores from a tuberous sclerotium would 

 hardly seem sufficient to segregate this genus from Pocillaria; 

 especially in view of the fact that the mycelium of some species 

 of Pocillaria tends to assume the sclerotial form when growing 

 in decayed wood mixed with earth, and that this form is found 

 in several widely different groups of fungi, apparently for the 

 purpose of rest and protection until sufficient food can be stored 

 up to insure the production of sporophores. 



A few of the tropical American species of this genus have 

 been recently figured in Romell's report of 1901 on the fungi 

 of the Regnell Expedition, and in Earle's paper on Cuban fungi 

 published in the first annual report of the Cuban Experiment 

 Station. Most of them, however, keep well in the dried state, 

 and it is usually possible to restore them to their original form 

 by placing them for a short time in a moist chamber.
