Sturgis: Myxomycetes of Curtis Herbarium 213 
“ OsTRACODERMA SPADiCEUM Schw. ram. dej. Mori albae. Herb. 
This name appears to have been overlooked by the monograph- 
ers. It was published in Syn. Fung. Am. Bor., p. 262, 1831. The 
specimen is normal Dictydiaethalium plumbeum (Schum.) Rost. 
From the above notes it will be seen that my observations are, 
in most cases, merely corrobrative of those recorded by the Lis- 
ters. The few instances in which I have been obliged to dissent 
from their opinion or in which further study has resulted in 
changes in the hitherto accepted synonomy, are as follows :
