J.S. Gardner (in Monogr. Palaeontogr. Soc. 1885, 38(185): 97. Jan 1886) stated that "quite disconnected, short, elevated, dotted, and spindle-shaped regions, discernible in the fossil, and mistaken by Massalongo for parasitic fungi". “Flor. foss. Senigalliese, 1859, p. 87, pl. i, fig. 1, Sclerotites salisburia, Massal. Saporta has suggested in a letter, and Mr. Murray of the British Museum has confirmed the view, that these are resin chambers. They are referred to by Dr. Bary (‘ Vergleichende Anatomie,’ English translation, p. 442) :— ‘In the lamina of Ginkgo, in place of the uninterrupted canals, there are, between the vascular bundles, short cylindrical sacs, 1 mm. or more in length, which are closed blindly at both ends.”
