 winter. The ascospores are mature and capable nf intectinn 

 at the beniiinin- of .lune. In forests nf 

 pure larch, or in mixture with spruce, the 

 ascospores are easily distributed by wind. 

 In larch, underplaiited with beech, the spores 

 are kept dnwn t< -wards the ground by the 

 caimpy of beech fnlia-v, so that, durin- the 

 summer, they cannot be carried up to the 

 larch crown.
