Eleven species are common to Europe and America, and one Australasian 
species is also European. 
In the following arrangement of the species the primary sections 
depend on the presence or absence of cystidia, and on the rough or smooth 
epispore. There will undoubtedly be a difference of opinion as to the 
relative value of the above characters in the discrimination of species. On 
the other hand, perhaps all will agree as to the advantage of having the 
characters of cystidia and spores, obtained from type specimens, added 
to the original diagnosis of species from which they were originally omitted. 
This I have been enabled to do through the generosity of the following 
mycologists in giving or lending type specimens, and to each of whom 
I express my thanks: — Dr. E. Boudier, Professor Dr. F. R. Kjellman, 
Dr. P. Hariot, Professor C. H. Peck, Dr. L. Romell. 
Inocybe, Karsten. 
Pileus symmetrical, flesh thin, covered with a fibrillose veil which 
becomes either longitudinally cracked, or broken up into squamules or 
squarrose scales, dry or rarely viscid ; gills adnate, adnexed or nearly free, 
brownish or dingy ; spores pale brown, epispore smooth, warted or 
spinulose ; cystidia often present ; stem central, slender, fibrillose, often 
peronate with squamules or squarrose scales up to the imperfectly defined 
annular zone. 
The genus Inocybe is most closely allied to Hebeloma , under which at 
one time it was included. The last named differs in the constantly viscid, 
pelliculose veil which is never fibrous and silky, whereas in Inocybe the veil 
covering the pileus is always distinctly silky or fibrous, even when viscid. 
The majority of species grow on the ground in woods or damp, 
shady places.
