Phyllocoptes fraxini Nalepa 684 
Houard, No. 4642. 
Connold (Veg. Galls, pi. 74; Plant Galls, fig. 34) 
delineates galls which he ascribes to this mite, but which, 
judging from his description, are the young state of the 
galls caused by the psyllid Psyllopsisfraxini. He makes 
no allusion to the hairs; the purple streaks are very 
characteristic of the psyllid galls. 
Branches swollen, then fissured. A thickened irregular 
margin of living bark forms around the wound, giving 
rise to the familiar cankered appearance.
