Sphaeria tuberculosa Hist. 123 f. 1

Tubercled Sphaeria

Frequent on the Branches and boughs of
the Maple Tree when in a dead & decaying state.

This plant has been taken by some for
a Lichen, by others it has been made a valsa,
The great Haller gave the name sphaeria to
the genus of which it is a species, I have magnified
one of the Tubercles to shew [show] the characteristic
of distinction in that genera.

A is a Vertical section of the Tubercle.
B an horizontal sectrion, in both which I have 
shown the natural situation & arrangement of
the spharulea which contain [illegible] seeds, and mark the
genus.
