Figure 18.-Phenology of C. comandrae and hosts in Beaver Mountain plot in 1964 in response 

 to weather conditions. In these diagrams, the seasonal extent of presence of fruiting 

 bodies, number of spores trapped by gravity, growth of comandra shoots and duration of 

 flowering, and growth of lodgepole pine may be studied in relation to the precipitation 

 and temperature conditions existing during the period May through October.
