polymorphic and the paraphyses are enlarged and organised so as 

 to form a continuous system. The Bolbitius Sub-type, of those so 

 far discussed, stands nearest to the Armillaria Sub-type, for its 

 spore-bearing basidia are more or less loosely spaced or have a

scattered arrangement ; but, in a Bolbitius, the basidia are restricted 

 in number in correlation with the ephemeral nature of the fruit-body, 

 and the paraphyses are relatively very large and form a continuous 

 system of cells in which the basidia are embedded. I am inclined 

 to believe that the Armillaria Sub-type has been the parent of all 

 the other Sub-types of the Aequi-hymeniiferae, including the Inocybe 

 Sub-type about to be described.
