The history of this fungus has been that of most of our abund- 

 ant, widespread and variable species : it has been named and re- 

 named again and again in various i:ountries by mycologists not in 

 touch with each other and not conversant with the work already 

 done, until, with types gone and data lost, it seems wellnigh im- 

 possible to follow the various specific and varietal names with 

 exactness. The above list, however, while not complete, repre- 

 sents fairly well the best known synonyms since Willdenow first 

 described it in 1787. 



Four or more new names have been given the plant in this
