 brings together species which are 

 separated from all the following 

 Leucospori on account of the veil. 

 On account of the disappearance of 

 the universal veil the species of the 

 fourth group of the Amanitcs are apt 

 to be looked for here. Fr. Hym.

There are three types ; the first 

 agreeing in every respect except the 

 ringed stem with the Tricholomata, 

 the second with the Clitocybae and 



the third with the Collybise. Most of the species grow on the 

 ground and are rare. Their qualities are doubtful. 



* Tricholomata subannulata. Gills sinuato-adnexed, stem fleshy, similar in 

 substance to the pileus. 



** Clitocybae annulatae. Gills attenuated behind, more or less decurrent 

 "without a sinus, stem solid. 



*** Collybiae annulatae. Gills equal behind, stem externally somewhat car- 

 tilaginous. 



* Tricholomata subannulata. Gills sinuato-adnexed, &*c.
