1)4! MICEOSCOPIC FUNGI. 



Thus it will be seen that^ inasmucli as we liave 

 complex brands in wliicli 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. Whilst 

 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 Tuhercirda. No doubt has yet 

 been thi'own on the genuine character of either of 

 these genera. No TJredo or ^cidvwm, no Trichohasis 

 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.
