a. Fibrous fungosity, supporting the seminules.
h. Seminules escaped from the cistule.
Fig. 8. Sphaeria stigma. Sarcotkalamece. Cut vertically
as it grows within the bark of the hazel-nut-tree, and very
much magnified. /^S/^
a. Partition dividing the sphserule into two cells.
Fig. 9. Physarum. Fungi. Several plants as they growon
dead timber, magnified.
a. Peridium cracked at top, showing the internal cells
containing the seminules.
Fig. 10. Puccinia rosse. Frotomyci. A group of plants
as they grow on the under surface of the leaves of the

titions transverse.
c. A very young plant.
d. An old plant, the peridium of which is torn, and the

of a branch very much magnified.
a. Conceptacles globular, solitary, sessile, just under
the tip.
I'. Small pappus on the tip of the conceptacles.

ceptacle.
d. Barren branch, terminated by two small lanceolate

Fig. 12. Girardia atropurpurea. Hydropliytce. Parts of
the plants, as they float in water, very much magnified.
a. A young filament, having only a dark line, without
any appearance of cells.
b. A filament in a more advanced state of growth, in
w^hich the partitions begin to be visible, with a small rectangular
seminule in each.
c. A filament still more advanced in growth, in which
the seminules have changed their position.
d. A filament containing two seminules in each cell.
e. K filament in which the two seminules have changed
position.
f. A filament in which the cells are become obliterated,
and being ruptured, let the seminules escape.
