Sphaeria concentrica Hist. 180

Concentric Sphaeria

This noble Plant I suspect has not before
been figured since the time of Michelii
who has figured it Gen: Plan: Tab. 62.
He has separated and magnified some of the
old empty seed vessels which constitute the
internal substance, but unluckily overlooked
the fertile and pregnant ones which are only 
to be found in the last formed stratum
close under the Bark, as seen at a Tab 240.
I believe is a species distinct from the Sycoperdon
Nigrum, Schaffer Tab: 329.
