tissue of fungi was strikingly illustrated a short time since in a 
grain elevator at Buffalo, N. Y. ; v . 
The aspflalt flooring of the building was over a f oot thick, m two 
layers; The upper layer was seven inches thick, and was laid hot, 
rolled down, and thoroughly cooled four years ago. Below this there 
was an old floor of tar and gravel, six inches thick. A. curious bulge in 
the floor was first noticed, covering about a square foot. In six hours 
the floor was burst open, and a perfectly formed toadstool, with a 
stem two inches through and a very wide cap, made its appearance. 
Elsewhere the floor was smooth: and unbroken.
