Fig. 67. Cymadothea trifolii. A. Conidial pustule in section of the stage 

 known as Folythrinciinn trifolii. The nodose, wavy conidiophores bear 

 scars from which the two-celled conidia are abstricted. B. Diagrams show- 

 ing stages in production of conidia such as might occur on a single conidio- 

 phore. The undulate appearance is the result of sympodial branching. 

 C. Nodose conidiophore bearing a series of scars from which conidia were 

 abstricted. D. Conidia, some of which are germinating. E. Portion of wall 

 of spermogonial locule, with spermatiophores and spermatia. F. Young 

 perithecial locule in section. The trichogyne projects to the surface and 

 the multinucleate cells belong to the basal part of the carpogonium. G. 

 Edge of perithecial stroma, showing locule in section with one mature 

 ascus and others all immature. H. Ascospores, one germinating.
