FUNGI INJURIOUS TO THE QUINCE. 147 
infrequently, as a rule, and without serious results. It 
might be said in passing, that the quince, including its 
foliage, branches and roots, has no less than ninety-six 
kinds of fungi upon it. Some of these that prey to a 
disastrous extent upon the fruits are also found upon 
the leaves, causing them to blight and fall away. This 
is a matter of considerable importance when the question 
of remedies is taken up later. 
The fungi treated in the following pages are arranged 
somewhat in the order of their appearance in the orchard, 
and not as to their ultimate injurious effects. Many of 
the engravings are from photographs of the specimens, 
and, of course, all color and something of the other 
characteristics are necessarily lost. However, it is hoped 
the reader may be able, by their aid, to fully understand 
the text, and obtain through both an insight into the 
nature of these troubles. 
THE QuiINcE Rust (Restelia aurantiaca, Pk.).—The 
first fungus to make its appearance upon the quince 
fruit in early summer is the rust. While the fruit is 
quite small the fine threads of the rust plant grow 
through it, and in one or more places the green color is 
replaced by orange, the quince at the same time usually 
becoming distorted. In the orange patches small pim- 
ples appear, which continue to enlarge, and from them 
short horns project and soon become ruptured at the 
top. Within these horns or tubes the bright orange 
spores are borne in great abundance and readily fall out. 
Four young quinces thus ruined by the Restelia are 
shown in Fig. 138, and the horns or spore-bearing tubes 
may be seen projecting from the surface of the young 
fruits. As time passes, the affected fruit, failing to 
grow or enlarging but slowly, becomes hard by drying, 
and either falls to the ground or remains upon the trees 
as a worthless and unsightly product until the close of 
the season,
