but Fairy Ring Spot is very appropriate and dis- 
tinctive. (See illustration of Fairy Ring Spot.) In 
its early stage Fairy Ring Spot may be detected 
as a small elevated knob, or discoloured blister, and 
nearly circular in outline. The spot becomes brown 
and indicates that the spores are escaping owing to 
the bursting of the skin of the leaf. As the opening 
becomes larger the dark brown spores cover a larger 
area of the leaf surface, and the spot presents 
different shades of colour according to the density 
or number of the spores. The fungus radiates from 
the centre, and the spot becomes an oval patch, or 
two or more patches may unite in one of irregular 
outline. The dark and light colours of each original 
spot, however, are arranged concentrically, like 
miniature fairy rings, hence the applicability of the 
Farry RING SPOT OF CARNATION. 
(Feterosporium echinulatum. ) 
popular name. The whole surface of the leaf, both 
the upper and under sides, may soon get covered 
with these brown patches, and its case becomes 
hopeless owing to the destruction of the leaf tissue. 
The mycelium of the fungus forms an interlacing, 
felted mass, and gives off erect branches ,at the tips 
of which oval or oblong teleutospores are formed. 
These spores vary with two to six cells, according to 
their length, and the outer thick walls are covered 
with projecting points. 
REMEDIES.—Fairy Ring Spot is a more destruc- 
tive fungus than the ordinary Carnation Spot, but it 
may be combated by the safe remedies already men- 
tioned. The causes which favour Carnation Spot 
also encourage Fairy Ring Spot.
