together, hut in such eases those on the face of the gill are 

 always of the crested type, while the edge is provided with both 

 kinds, occasionally with intermediate forms. The trivial kind 

 never occurs on the face of the gill. Some authors, f. insl. 

 Massee and Bataille, reserve the name cyslidia for the muri- 

 culate type only, and consequently divide the species in cystidiate 

 and cystideless series. 



When we come to the minor subdivisions the old Fries'ian 

 characters must be taken into consideration. But of the 5 tribes 

 established by him the last and smallest (uiscidi) is broken up 

 by removing Agaricus Tricholoma and its allies from the genus 

 altogether (as is now generally done); and the remaining species 

 — which are however unknown to me — probably better can be 

 placed within one group or other of the remaining 4, as they 

 naturally fall in with the subviscid species of these (f. inst. /. 

 umbrina and /. prcetervisa). With regard to the remaining Fries'ian 

 tribes I think the line of demarcation between squarrosi and 

 laceri is rather vague; and the same may be said of rimosi-veluiini 

 I therefore deem it more practical to unite 1 & 2 and 3 & 4 

 respectively. 



Although the smell of most fungi is very characteristic and 

 constant, it is of small value for classification-purposes, as it is 

 too difficult to define. Very few, if any, of the Inocybes are 

 entirely inodorous, most of them have a faint but disagreeable 

 earthy« or spermatic smell. But the strong aromatic smell of 

 /. pijriodont and several other species — generally compared 

 to the smell of Calycanthiis-flowers or over-ripe pears — is so 

 unmistakable that it can be profitably used for characterizing 

 this little group of closely related species. 



The minor details of my classification can be seen in the 

 Key and will require no particular explanation. 



From the adjoining genera Inocybe is generally well disting- 

 uished. Some modern authors (Schhoeteh, Sev. Petersen a. o.) 

 transfer the indusiate species of Hebeloma to Inocybe, but this 

 can hardly be considered a real improvement. The indusiate 

 and the veil-less Hebelomas are so intimately related in all other 

 respects (also with regard to their microscopic characteristics) 

 that I think it absolutely preferable to maintain the old Fries'ian 

 line of demarcation. To separate f. inst. H. longicaudum and 

 H. testacenm, H. crustuliiriforme and H. faslibile cannot be done 

 without ignoring true relationship. Besides, if veil or no veil is
