Lons-le-Saunier, Lucien Declume, 1900. 8vo (24.2 x 15.8 cm). 184 pp.; 74 text figures. Contemporary half calf over marbled boards. Spine with gilt title. Marbled flyleaves. Original printed front wrapper bound in.

A fine and rare monograph by the French chemist and mycologist Narcisse Théophile Patouillard (1854–1926), with detailed drawings and including new taxa. It was reprinted in 1963 (a seldom-seen edition), but this is the much rarer original publication and, moreover, an interleaved copy. Some light rubbing to the boards, otherwise a good clean copy. Stafleu and Cowan, 7483; Volbracht, 1549.
