THE INOCYBE SUB-TYPE

section and positively geotropic, the hymenium looks downwards 

 to the earth, and every part of the hymenium produces and liberates 

 spores during the whole period of spore-discharge. 



The special characters of the Inocybe Sub-type resemble those 

 of the Panaeolus and the Armillaria Sub-types, except for the inter- 

 mediate structure of the hymenium, and may be stated as follows : 



(1) The whole structure of the fruit-body is relatively stout and

suited to a persistence of the opened pileus for several days. In this 

 respect, therefore, the Inocybe Sub- type resembles the Panaeolus 

 and Armillaria Sub-types, but differs from the Psathyrella and the 

 Bolbitius Sub-types. 



(2) The spore-discharge period is relatively long : its duration 

 is for several days. Here again, we have a contrast with the 

 Psathyrella and the Bolbitius Sub-types but an agreement with 

 the Panaeolus and the Armillaria Sub-types. 



(3) In species with pigmented spores, the gills are not strongly
