Murrill: Poisonous Mushrooms 



259 



Ceriomyces miniato-olivaceus (Frost) Murrill 

 Poisonous to some and harmless to others. A case of poison- 

 ing by this species was reported by Collins in Rhodora for 1899. 



Suillellus Eastwoodiae Murrill. 

 Properties unknown, but belonging to a suspicious genus. 



Suillellus Frostii (Russell) Murrill 

 Usually viewed with suspicion because of its red hymenium, 

 but its properties are not accurately known. 



Suillellus luridus (Schaeff.) Murrill 

 Avoided by most persons and said to contain a small amount 

 of muscarine or closely allied alkaloid, as well as choline, but 

 eaten by others for many years without harmful effects, both in 

 this country and in Europe. Owing to the variety of its forms, 

 it is liable to be confusing unless one uses the red tube-mouths 

 as a distinguishing character and avoids the whole genus, which 

 is the wisest thing to do until its species are more thoroughly 

 tested. 



Suillellus Morrisii (Peck) Murrill 

 Properties unknown. Taste mild, but the species, which is 

 very rare, needs to be tested. 



Suillellus rubinellus (Peck) Murrill 

 Properties unknown. Taste mild, but the species needs to be 

 tested. 



Tylopilus felleus (Bull.) P. Karst. 

 Usually intensely bitter, both raw and cooked, and therefore 

 inedible, but not generally considered poisonous. 



AGARICACEAE 

 Amanita cothurnata Atkinson 



This species was collected in quantity in Virginia during the 

 past summer for investigation. While drying the fresh sporo- 

 phores in the sun, hundreds of flies were attracted to their viscid 

 surfaces and were paralyzed in great numbers after sucking the 

 juice, thus indicating a close relationship with A. muscaria.
