422 ENUMERATION OF FUNGI. 
is filled with a closely-packed mass of yellow sporidia, mixed 
with a few hyaline filaments. Spores globose, with a globose 
nucleus. 
It is unfortunate that I have had an cpportunity of inspect- 
ing only a single specimen of this curious fungus, and that 
rather in an advanced stage of growth. It is so different, 
however, from any other puff-ball, especially in its hollow 
stem, that there can be no danger in proposing a new genus 
for its reception, though the characters assigned are neces- 
sarily imperfect, from ignorance of the early condition of the 
fructifying mass. The colour of the sporidia is like that of 
some Polysacca, but there is no trace of cells; and, indeed, 
the sporidia themselves do not resemble those of Polysaccum. 
Its true affinities, at present, must remain obscure. It is 
probable that the fructification will prove of the same nature 
as that of Scleroderma, near to which genus it may fitly be 
placed. The spores are most abundant, and pollute every 
thing they come near. The colour of the fungus is yellow 
from the sporidia, but when fresh, is probably white.

The stem in this species is straight, not twisted. The 
mass of filaments is covered with a very delicate peridium, 
distinct from the coarse calyptreform coat. The colour of 
the sporidia changes extremely as the plant advances to ma- 
turity. The portion at the base exposed to light, becomes 
black, while the portion shaded by the top of the calyptra is 
yellowish. The shape of the peridium also varies from ellip- 
tic to oblong. | 
The affinities of this and the neighbouring genera have 
lately been discussed by Dr. Montagne, in a paper read be- 
fore the Société Philomatique of Paris, April 15, 1843. An 
abstract of it is given in Institut, May 4, 1843, a translation 
of which is appended to this memoir.
