First edtions of an illustrated work on cryptogams in Germany. The work consists of three parts, dealing respectively with "Flechten" (lichens), "Pilze" (fungi) and "Lebermoose" (liverworts or hepatics). The first part on lichens was written by the German botanists Walther Otto Müller (1833-1887) and Gustav Pabst (d. 1911), while the other two parts were written by Pabst alone. Each part gives taxonomic descriptions of the cryptogams, of which many are shown in the plates. Due to its accurate coloured lithographs of fungi, showing a wide variety of them, the second part is considered to be the most valuable. "Das beste unter den weniger umfangreichen Abbildungswerken deutschen Cryptogamen. Die Illustrationen sind so scharf, das sie Kupferstich ähneln" (Junk).
Slightly browned throughout with some occasional foxing in the first and the third part, only affecting a few of the plates. Binding worn along the extremities. Otherwise in very good condition. Junk, Rara 17; Myko Libri 1530; Nissen, BBI 1427; Stafleu & Cowan 7175.
