Rugose, wrinkled. 



Saccate, liquefaction in form of an elongated sac, tubular, cylindrical. 



Slow, requiring five or six days for development. 



Spindled, larger at the middle than at the ends. Applied to sporangia, refers 



to the forms frequently called Clostridia. 

 Sporangia, cells containing endospofes. 

 Spreading, growth extending much beyond the line of inoculation, i.e., several 



millimeters or more. 

 Stratiform, liquefying to the walls of the tube at the top and then proceeding 



downwards horizontally. 

 Transient, lasting a few days. 

 Truncate, ends abrupt, square. 



Turbid, cloudy with flocculent particles; i.e., cloudy plus flocculence. 

 Umbonate, having a button-like, raised center. 

 Undulate, border wavy, with shallow sinuses. 

 Viscid, growth follows the needle when touched and withdrawn; sediment on
