Harper: Identity of Stropharia epimyces (Peck) Atk. 169 
have been found ^simply adnexed instead of adnate to adnexed, 
etc. The collector of plants like those found by Peck or Miss 
Sherman, who attempts to use Atkinson’s description, will find 
Himself in a predicament understood by everyone who has at- 
tempted to identify agarics from descriptions. 
An interesting result of Lanzi’s work in making Pilosace algeri- 
ensis known in Europe is that Cooke’s illustration of that species 
in his plate 6i8 is shown to rest on an incorrect determination. 
The figure has been copied far and wide as an illustration of the 
genus. Lanzi suggests that it may be based on an exannclate 
form of Agaricus campestris such as that figured in Cooke’s plate 
528.
