Coralliform Quartz

Tab. CCXCIII is another species, branching like roots dividing upwards, as happens in some plants, and the transverse section would accord with that notion to those not so conversant with Corals as with Plants; and in tab. 289 and 290 the divisions somewhat resemble the alternating lamellæ of the tribe of Fungi called Agaricus, a form that has given the name of Fungites to Corals, especially fossil ones. The cells concentrate, and the outside remains broken, much resembling some plants with decayed stumps. The specimen here figured somewhat resembles Madrepora anthophyllites, figured by Solander and Ellis, tab. 29, but the branches are not so club-shaped.
