94 MICROSCOPIC FUNGI. 



Thus it will be seen that^ inasmucli as we have 

 complex brands in which, the number of cells are 

 considerably increased^ so have we ^^complex smuts^^ 

 in which^ instead of one cell, we have many. In 

 the last instance the two genera associated together 

 in this chapter agree. The spores in both are 

 distinctly cellular_, but in the last genus far more 

 opaque and consolidated than in the first. WhUst 

 it may be doubted whether the compound spores of 

 Polycystis are anything more than a number of 

 individual spores with a gregarious habit^, invested 

 with an outer membrane, such a hypothesis cannot 

 (as far as our individual examinations extend), be 

 made to include Tuhercinia, No doubt has yet 

 been thrown on the genuine character of either of 

 these genera. No Ureclo or JEciduim, no Trickohasis 

 or Puccinia has been ascertained or suspected to 

 appear as a prior or subsequent form. In their 

 supposed integrity they offer an interesting study, 

 and in their development a good subject for inves- 

 tigation.
