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 
Leptoniella 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. abortivus, 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. personata, 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. Murrait) 
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. Murra, and E. salmoneum. 
Because of the very poisonous European species, E. lividum, the mem- 
bers of this genus have been largely avoided by mycophagists.
