EXOSPORE^E. The Exosporese, or Myxies which carry 

 their spores on the surface and not in the inside of the 

 sporangium, consist of one genus Ceratomyxa and of 

 two species, or, according to other authorities, of one 

 species only with one variety. Of this small organism a 

 drawing will be found in Fig. 15. Its first describer, 

 Micheli, called it Puccinia 

 ramosa (in 1729). In 1805 

 it was called Ceratium 

 hydnoides by Albertini 

 and Schweinitz. It was 

 described as Ceratomyxa 

 mucida by Schrater in 

 1889, and, as that name 

 is adopted by Mr. Lister, 

 whose works are the most 

 convenient for the English 

 reader, we have thought 

 it best to follow him. 

 But we have given the synonyms to prevent our readers 

 from being misled by the puzzling and lamentable variety 

 of names. 



The Ceratomyxa mucida is by no means uncommon on 

 rotten wood, and might at first sight be mistaken for a 

 white or pale-coloured fungus. It consists of an aggrega- 

 tion of finger-like projections from a common base, and 

 presents somewhat the appearance of a minute piece of
