MURRILL: ROSY-SPORED AGARICS 335 



The other species of the genus occur in the eastern United States, 

 from the Atlantic seaboard to the Rocky Mountains. 



2. ECCILIA 



The best known species is E. atrides, of the eastern United States. 

 Three species are confined to the Pacific coast, and four to tropical 

 North America. 



3. Leptoniella 



LeptonieUa serrulata, characterized by the black, serrulate edges 

 of the lamellae, is the best known species. Four are confined to the 

 Pacific coast and seven to tropical North America. The rest occur in 

 the eastern United States. 



4. NOLANEA 



The two best known species are N. conica and N. mammosa, the 

 latter distributed throughout temperate North America but not 

 generally recognized by mycologists. One species is confined to the 

 Pacific coast and three to tropical North America. 



5. Pleuropus 



This genus contains many edible species, among them P. prunulus, 

 P. orcellus, and P. ahortivus, the last readily distinguished by the 

 peculiar aborted hymenophores. Two species are confined to the 

 Pacific coast and one to tropical North America, 



6. Lepista 



One of the best edible species we have is L. per sonata, better known 

 as Tricholoma personatum. This species and L. tarda occur through- 

 out temperate North America. Two other species are confined to the 

 eastern United States, and there are none known from tropical North 

 America. 



7. Entoloma 



This also is a temperate genus, the only species (E. Murraii) 

 reaching tropical North America being found in the high mountains 

 of Jamaica. Four species are confined to the Pacific coast. The 

 best known species in the eastern United States are: E. strictius, E. 

 Grayanum, E. sericeum, E. rhodopolium, E. Murraii, and E. salmoneiim. 

 Because of the very poisonous European species, E. livid um, the mem- 

 bers of this genus have been largely avoided by mycophagists.
