Doubtful species 



Amanitopsis adnata (W. G. Smith) Sacc. Syll. Fung. 5: 24. 1887. Described from Eng- 

 land, and reported from this country by Morgan, Harkness, and others. I have seen no 

 American specimens that could be so referred. 



Agaricus baccatus Fries, Epicr. Myc. 12. 1838. Founded on Micheli's plate 80, figure 4, 

 accompanied by a brief description. The warts on the pileus are too evenly distributed, and 

 the volva is too small and circumscissile to suggest our Vaginata agglutinata. If an annulus 

 were present, the figure might suggest white forms of Venenarius pantherinus. 



Amanitopsis hyperborea P. Karst. Hattsv. 1: 7. 1879. Reported from Greenland by 

 Rostrup (Medd. Gronl. 3: 528. 1888), but I have not seen it among American collections. 



Agaricus praetorius Fries, Epicr. Myc. 11. 1838. Specimens of Venenarius Caesar eus 

 from America have been referred to this species. 



Amanitopsis pubescens Sacc. Syll. Fung. 5: 25. 1887. Amanita pubescens Schw. Schr. 

 Nat. Ges. Leipzig 1: 79. 1822. Described from specimens collected in grassy places in 

 North Carolina. Schweinitz said it was rare, and Morgan, Beardslee, and others say that it
