Bologna, L. Cappelli, 1922-1930. Ten parts in eight. Folio (28.0 x 21.8 cm). Text; 100 microscopic slides with specimens under sealed cover slips, and printed labels. Uniform dark green half cloth portfolios with gilt lettering on the front boards, and small paper label on the spines.

A complete set of a very rare publication by the Italian mycologists Gino Pollacci (1872-1963), and Arturo Nannazzi (1877-1961). Each volumes contains ten different fungi including a sample of the actual species, and a loose-leafed illustrated text describing and illustrating each fungus, also often including the fungus' pathological effect on humans and/or on cattle or other mammals, and fowl (and one, number 61, botanical). Some parts have more general text pages as well. Most illustrations are in black and white, but full colour illustrations are present too. Part V has a general index to the first five parts, Part X an index to all parts. The name of the publisher, L. Cappelli, is pasted over another name (S. Bernardino) on the title pages of the first six parts. Parts VII-VIII, and IX-X are combined in two portfolios. One board a bit rubbed, otherwise a near mint, complete set, with all the slides intact. We could trace a few complete copies in Italian libraries, but not even one elsewhere. Exceedingly rare. Not in Volbracht (neither in the 2017 supplement).
