This fungus was formerly referred to the subgenus Clitocybe, 

 but later observations indicate a closer relationship to Omphalia. 

 It is closely related to such species of Omphalia as O. affricata, 

 0. tehnaticea, 0. sphagnicola and 0. philonotis. From all these it 

 differs in the peculiar adornment of the pileus, 



Omphalia montana Pk.
