"SUMMKK SPOUKS" <)l llli: FUNGUS. 



These strings or "horns" of conidia arc extruded from the pustules of the fruiting fungus on 

 all the cankered limbs. At f^rst the eonidia are bright yellow or greenish yellow, but they 

 gradually turn darker with age. These conidia are by no means always iiresent, however, 

 and in some cases, as in young nursery stock, it is exceedingly difticult for anyone except 

 an expert to detect the presence of the fungus. (Figure 6.)
