178 THE NORTHERN MICROSCOPIST. 
nemorosa already mentioned, there is a white cluster cup. .&. /eu- 
cospermum, one of the most beautiful, but not often found in this 
district ; I have often met with it in the Lake District and once 
in Wales. There are two rusts, as they are commonly called, 
which may now be found upon the leaves of the willow, Lecythea 
saliceti and L. mixta. The willows about Northenden and other 
marshy districts are annually infested with these rusts, and are 
easily found. A very beautiful one, Z. Valeriane on V. officinales, 
is more rare; I have but once found it, and that was in a wood 
near Taddington, in Derbyshire. From this time during the 
summer, an interesting white fungus may be found upon the 
Shepherd’s Purse ( Capsella bursa-pastoris.) Itis Cystopus candidus, 
and the same fungus may be found also upon cabbage and other 
Cruciferee. The former of these is very common, but the latter is 
more rare ; I have only met with it twice, once at Deganway, near 
Conway, and the other on the north coast of Devonshire. Another 
Cystopus C. cubicus is pretty common on the goat’s beard. 
Puccinia saxifragarum should have been mentioned in last month’s 
notice, but it may still be found in favourable situations. It is 
known as the Moschatel brand, and is found on both surfaces of 
the leaves of Adoxa moschatellina. Numerous other micro-fungi 
are now to be found in almost every field or upon every hedge- 
bank. Grasses, leaves of trees, and plants of all kinds are liable 
to be infested, so that the student who earnestly seeks for interest- 
ing objects of this kind will very rarely return from a ramble in 
the country unrewarded.—Zvos. Britain. 
LEPISMA SACCHARINA.—This active little insect, the scales of 
which were at one time in great request as test. objects, is often 
found upon the shelves of cupboards, in window cracks, between 
books, and many other places in the household. It is shown 
magnified in fig. 31. 
Fig. 31. 
The body is elongated and flattened, the antennz setaceous, with 
numerous very short joints; four palpi, the abdomen terminated 
by three long jointed filaments.
