When young, naked, mobile, in consequence of which the masses 

 of plasm odium have a changing form. These masses at the time 

 of fructification sometimes dividing themselves into single parts, 

 are transformed into motionless fruits. Fruit either irregular in 

 form (plasmodiocarp) or regular (sporangium^). Sporangia, through, 

 fusion and union, produce, now and then, compound fruits (^Etha- 

 liuni). ./Ethalium. usually of considerable dimensions, of regular 

 or irregular form, naked, or covered with a common coat (cortex). 

 Spores produced within the fruit through free- cell formation, or on 

 the surface through division. The contents of spores at the time 

 of germination, give rise to either at first a naked zoospore pro- 

 vided with a nucleus, a cramped vacuole, and long cilia, or to an 

 amaeboid. These zoospores, or ama^ba?, flowing together in masses, 

 give rise to mobile plasmodia. Rstfki. Mon , p. 83.
