 nection. 

 CLAMP-CONNECTION, a semi- 

 circular process connecting two 

 adjoining cells of a hypha. In 

 some cases it may communicate

 others its extremity becomes 

 applied to the wall of the ad- 

 joining cell, at which point 

 both walls are absorbed, leav- 

 ing a passage around the sep- 

 tum between the cells of the 

 filament. The process may 

 become cut off from the origi- 

 nating cell by a septum when 

 it is called a " clamp-cell." It 

 is found mainly in Basidiomy- 

 cetes.
