mon species (more common perhaps in Scotland than in 

 England), and may be known from some other allied forms by 

 its gills being much attenuated behind. It is, however, ex- 

 tremely variable. But few species have been distinguished in 

 this country. One of the most remarkable is A. Babingtonii, 

 which has the grey shining pileus adorned with dark-brown 

 little tufts of fibres which are free at one end, and a somewhat 

 strigose stem. A. rubidus, a very small species figured in the 

 first volume of the Magazine of Zoology and Botany, occurs 

 occasionally on soil in hothouses, but whether really indigenous 

 or not I am uuable to say. 



There remains only the small subgenus, Eccilia (from 

 €K/cci\o<;, hollow inwardly), which is distinguished by the truly 

 decurrent gills and umbilicate pileus. Like Leptonia, it has the 

 margin of the pileus incurved. A very beautiful species lately 

 figured in the Annals of Natural History, occurred at Aboyne, 

 the subgenus being previously unrepresented in this country. 



DESCRIPTION OP PLATE. 



Besides Agaricus incanus, Fr., which has already been 

 adverted to in the present paper, the following species, to 

 which reference will be made in future notices, are figured in 

 the coloured plate. 



2. Agaricus (PJioliota) fiammans, Fr., a very beautiful 

 species^ especially in a young state, which occurs in pine 

 woods in Scotland, attached to fallen branches, and is distin- 

 guished by its bright yellow pileus, clothed with superficial 

 hairy scales ; its rough stem and yellow entire gills. 



8. Agaricus (Psalliota) albo-cyaneus, Desm., a species 

 which occurs in grassy pastures, and is very nearly related to 

 the common A. ceruginosus, but is far more delicate, and free 

 from scales, as is also the stem ; the gills, moreover, are not 

 so decidedly adnate. 



4. Agaricus (Hypholoma) appendiculatus , Bull. This is a 

 very widely diffused Agaric, assuming various forms, but 

 always known in its subgenus by the white veil being attached 

 in fragments to the margin, while the gills are at first whitish 

 and then rosy-brown. It occurs either on old stumps, or on 

 soil where chips have been rotting. 



5. Agaricus {Psilocybe) bullaceus, Bull. This Agaric grows 

 principally on horse-dung, and when not washed by rain is 

 pretty in form and colour. The pileus is hemispherical, very 

 smooth, but finely striate in the direction of the gills ; the stem 

 is short, and more or less fibrillose, and the gills are of a fer- 

 ruginous brown, very broad, and triangular. 



6. JRussula emeiica, Fr., remarkable for its splendid polished
