48 FUNGOID PESTS OF CULTIVATED PLANTS. 



FUCHSIA DISEASES. 



Although the Fuchsia is largely grown in this country, its enemies are 

 very few, and, so far as we are aware, none of a fungus origin have as yet 

 been found, although a leaf-spot is known in France. 



HOUSELEEK RUST. 



Endopliyllum Sempervivi (A. & S.). 



This peculiar parasite is somewhat intermediate in its character 

 between a uredo and a cluster-cup. The envelope which encloses the 

 spores is immersed in the substance of the succulent leaves, and bursts 

 irregularly to discharge the spores. 



The teleutospores, as they are termed, are for the greater part rounded 

 or obovate (25-35 x 20-32 p), with the surface warted and of a brownish- 

 yellow colour. They germinate after the manner of those of Puccinia. 



The species is known over the greater part of Northern Europe.

HONEYSUCKLE LEAF-SPOT. 

 Phyllosticta Lonicera (West), PI. III. fig. 56. 



The Honeysuckle may claim to be a garden flower, and is certainly a 

 favourite in cottage gardens. The leaf-spots are rounded and pallid, with 

 a brown margin, and the perithecia are quite small, appearing like very 

 minute dots upon the spots. 



The sporules are rather large for the genus to which they belong, 

 and are narrowly elliptical, with two nuclei (10-14x21-3^ p), and 

 colourless.
