a iF FUNGALS, 
Penicituium, Link. 
Microscopic. Cobweb-like or mothery flocculent masses, producing simple 
globose spores disposed in patches about the pencil-shaped ends of 
septate fertile threads, 
1. P. glaucum Greville.—(Tar Vinrear Punt.) 
Mycelium forming a close tough crust-like or leathery web ; branches some- 
what entangled and bifid ; spores verdigris-green. 
Habitat. On decaying bodies, and in fluids in a state of acetification. 
. . é sae . . dl the 
lity. Assists in the decomposition of decaying matter, and augments rapidly 
a fermentation of saccharine fluids, A bit placed in sugar and water soon 
changes it to vinegar. 
Mycoperma. It is probable that 
the flocculent substance which 
forms in various infusions when 
they become ‘ mothery,’’ and 
which bears this name, is only the 
mycelium of Mucor, Penicillium, 
and other Fungals of a similar 
nature, The accompanying cuts, 
from a paper of Mr, Berkeley’s, 
illustrate this. Fig. 29 is a view of 
the mycelium of Mucor subtilissi- 
mus as found in water, with one 
ball of the reproductive bodies 
formed when the mycelium reached 
e air; 30 is Penicillium candi- 
dum in the same state, the greater 
part of which had been formed in 
3 but a couple of branches 
reaching the air produced the true 
fructification of this genus of 
Fungals,
