NE'CTRIA. A genus of parasitic fungi, living on trees 

 and shrubs. They are often wound-parasites, gaining an 

 entrance to large limbs and branches after pruning, and 

 as a result of the attacks of American Blight, and injury 

 from hail and frost, the latter in the case of badly ripened, 

 late growths. N. diti'ssima, which is the cause of Apple- 

 tree canker, is one of the most common. The spores, 

 gaining an entrance, live on the decaying wood, and 

 killing live wood, are thus able to extend their work of 

 destructiveness, until the diseased part completely sur- 

 rounds the twig or branch, which then dies. The spores 

 are of two forms, namely, threads of conidia, which 

 break up into single cells or spores at the joints, and 

 ascospores, to the number of eight in asci or large cells. 

 Both of these forms are produced on and in the small 

 knobs which appear on the surface of the wounds, when 

 the fungus has reached the fruiting stage. This fungus 

 also attacks various forest and ornamental trees. More 

 common, perhaps, and more conspicuous is the coral 

 spot disease (Ne'ctria cinnabari'na), frequently seen on 

 dead and dying wood of red currants, sycamores, elms, 

 and other trees. The fungus is very noticeable on account
