The year 1755 saw the publication of Giovanni Antonio Battarra's Fungorum agri Ariminensis historia, an account of the fungi found near the town of Ariminum, now Rimini, in north-east Italy. The second edition appeared in 1759 and here is that edition's title page, showing the same illustration that appeared in the first edition. I have taken this from the copy of Battarra's work in the digital library (http://bibdigital.rjb.csic.es/ing/index.php) of the Real Jardín Botánico in Madrid.
The illustration features a lynx, in folklore a very sharp-eyed animal. Here is an enlargement of the picture:
The lynx has one paw on a mushroom and there are other mushrooms in the scene, as well as a solid, hoof-like bracket fungus growing from the trunk on the right. In the banner there is a sentence in Greek. Transliterated the banner reads mykas theoroumen ou phagomen and, in translation: we look at mushrooms but we don't eat them.
