2i 4 RESEARCHES ON FUNGI 



hundreds of fruit-bodies of fleshy Hymenomycetes observed, I found 

 very few which had not been visited and partially eaten by slugs. 

 Some of the fruit-bodies had been absolutely ruined by these 

 animals. Thus the stipe of a large Boletus flavus had been eaten 

 in two ; and the separated pileus had completely lost all its hymenial 

 tubes, whilst the pileus-flesh had become reduced to a thin per- 

 forated shell. A slug was found ensconced in one of the cavities 

 of the flesh ; and, doubtless, it was only waiting for the night to 

 sate its voracious appetite once more upon the wreck to which 

 it was clinging. Some other fruit-bodies, e.g. Russula ochroleuca, 

 Lactarius piperatus, and L. turpis, were almost equally damaged. 

 The following species were found to have been visited and partially 

 eaten by slugs :

Amanitopsis vaginata Hypholoma fasciculare
