The Mycetozoa, and 



white coral. When the surface of these projections is 

 examined, it is found to be marked off by delicate lines 

 into polygonal spaces, from the centre of each of which 

 rises a delicate white stalk, and on the summit of this an 

 equally delicate and white egg-shaped spore. 

 The development of this 



little organism has 

 elaborately studied by 

 two Russian botanists, 

 and it is sufficiently in- 

 teresting to demand a few 

 minutes' attention. Its 

 plasmodium emerges from 

 the wood in points about 

 the size of a pin's head, 

 and is found to be differ- 

 entiated into two elements 

 (1) a transparent motile 

 jelly, and (2) an irregular 

 network of opaque plasma 

 embedded in the trans- 

 parent jelly. These two 

 parts are shown in Fig. 16. 

 Gradually little promi- 

 nences are develope d on the 

 surface of the plasmodium, 

 and as these grow into the 

 finger-shaped projections, 

 the network of opaque 

 plasma appears just below their surface, the translucent 



FlG. 1 6. Ceratomyxa mucida. 

 Plasmodium showing superficial 

 transparent jelly, and opaque 

 strands. (After Famintzin and 

 Woronin.)
