Amanita fulvaAs you can see from his list of publications, Schaeffer was interested in all sorts of things, publishing books on crustaceans, insects, and paper-making. I wonder if his publications in those other fields are as basic to them as his mycological ones are. His book on colors is the earliest attempt that I know of to standardize color terminology. I have also heard that he published on minerals, but haven't seen titles for those works.

Nebst einer Kupfertafel in Farben (The imaginary toothed worms and the supposed remedies for them. With colored copper-plates.)
from Schaeffer's Abhandlungen von Insecten. Why it's in his Abhandlungen von Insecten, I have no idea.
And also, if you're claiming that a creature is imaginary, isn't it counterproductive to provide a color picture of it?

Jacob Christian Schaeffer (1759) Vorläufige Betrachtungen der Schwämme um Regensburg (Preliminary considerations on the mushrooms fungi around Regensburg)

Jacob Christian Schaeffer (1759) Isagoge in botanicam expeditiorem: iconibus aeri incisis et pictis illustrata (A self-taught botanist on expedition: illustrated with woodcuts and drawings) 98 pp.

This book is only 16 pages long, so not as important as the other (fungal) one.

I have seen this listed as a book on insects; evidently by someone who couldn't read the German title.

Translation of: Versuche und Muster ohne alle Lumpen, which is the first two volumes of the sämtliche papierversuche
