united to a base closely resembling the base of the other 
tubercles. If for a moment we look at one of the tubercles near 
the spot where the crimson tubercles seem to merge into the 
pink, we shall not only find them particoloured, but that the red 
points are the identical globose little heads just observed in 
clusters. This will lead to the suspicion, which can afterwards 
be verified, that the red heads are really produced on the stem 
or stroma of the pink tubercles. 
A section of one of the red tubercles will show us how much 
the internal structure differs. The little subglobose bodies 
which spring from a common stroma or stem are hollow shells 
or capsules, externally granular, internally filled with a gelatinous 
nucleus. They are, indeed, the perithecia of a spheriaceous 
fungus of the genus Wectria, and the gelatinous nucleus contains 
the fructification. Still further examination will show that this 
fructification consists of cylindrical asci, each enclosing eight 
elliptical sporidia, closely packed together, and mixed with 
slender threads called paraphyses. 
Here, then, we have undoubted evidence of Nectria cinna- 
barina, with its fruit, produced in asci growing from the stroma 
or stem, and in intimate relationship with what was formerly 
named Tubercularia vulgaris. A fungus with two forms of fruit,
