70 FUNGOID PESTS OF CULTIVATED PLANTS. 



vascular bundles with a yellow slime. This mucus is said to contain 

 immense quantities of a bacterium, to which at first the name of 



terium Hyacinthi was applied. 



'Whilst these little hodies are emhedded in the slime they remain 

 motionless, hut when removed from it they soon exhibit a lively motion, 

 and begin to divide. In the spring they appear in the vascular bundles 

 of the leaves.

Another disease attacks principally the flowering parts and is attended 

 by the production of a foul-smelling mucus. Upon making a close 

 examination Dr. Heine discovered that the mucus and the tissues were 

 full of bacteria, quite different from those of the "yellow disease," and 

 was called Bacillus Hyacinth i scpticus. It is reported that when healthy 

 plants are inoculated with this the evidence of infection is manifested 

 within twenty-fouf hours. When cultivated on Potato it formed a yellow 

 slimy layer, and in a few days gave off a strong offensive smell.

Tubeuf contends that a common large Pcziza, which grows on manure 

 heaps {Pcziza vesiculosa), attacks Hyacinths and other plants in gardens 

 and kills them.

COXVALLARIA BROWN Sl'OT. 



Srptoria brunneola (Fries), PL V. fig. 87. 



This leaf-spot is found, not uncommonly, on living or fading leaves of 

 Lily of the Valley, but not often in fruit, so that the spots remain sterile 

 ami harmless. It is believed, however, to be only a prelude or early stage 

 of a more highly developed fungus {Splnerella brunneola). 



Brown irregular spots on the leaves, which at length acquire a blackish 

 colour, precede tin receptacles of the Septoria, which latter subsequently 

 app' ittli dots clustered upon the spots. The sporules are long and 



tho iadlike, without division (75 100x2/*).
