 damage to the cultivated plants their life-cycle has, till now, been too 

 little investigated. As is the case with most species of Hypocreaceae 

 their conidial fructifications are of great importance to their propaga- 

 tion. Most of them produce one or more different forms of lower 

 fructifications from the same stroma. 



The best known is Nectria cinnabarina whose young stroma pro-
