302 SECTIOX HYGROPHORUS 



Fig. 92. H. fuligineus 



might apply to either H. fuligineus or H. paludosus. We have not noted 

 a tendency of the gills to become grayish in H. fuligineus, and since 

 H. limacinus is usually described as having spores 10 /* or more long, 

 we do not believe that H. fuligineus should be reduced to synonymy 

 with it. Bresadola ( 1928 ) mentions having studied dried specimens of 

 the American species, and states that its spores measure 8-10 X 5-6 fx. 

 The possibility that he actually examined a specimen of H. paludosus 

 in which the greenish and yellowish stains did not develop is by no 

 means excluded, since the two are very similar in many respects. In 

 spore deposits, however, the spores of H. paludosus are consistently 

 larger than those of H. fuligineus, the apex of the stipe of the latter is 

 not as scabrous, and there are differences in color in addition which 

 are sufficient to establish them as distinct. Murrill (1916) lists 

 H. fuligineus as a synonym of H. hijpothcjus, but the former does not 

 develop yellow colors as found in the latter.
