ACETABULAB1A. 233 



Agaricus acetabulosus, Sow., pi. 303. 



Found near Millbank, Westminster. A little above high- 

 water mark, in May 1795. This is very like a poor specimen 

 of Agaricus congregates (Coprinus micaceus), but the pileus is 

 more plaited. The lamellae are remarkably glandular on 

 their sides ; and instead of a bare base or foot it stands in a 

 little socket-like volva. (Sowerby.) 



The present species has not been noted since Sowerby's 

 time, and is a very uncertain production. Judging from 

 the magnified section of the gills, the glands on their sides 

 are cystidia.
