BIBLIOGBAPHICAL NOTES. 859 A few changes of nomenclature have been rendered necessary, notably in the Sordariea, a group to which Winter has devoted special attention. He gives great prominence to spore characters combined with the habit of the plant, and, following these lines, he has placed in three well-defined genera all those species that have non-septate spores : Sordaria, Hypocopra, and Podospora. The spores in the first two genera are alike, black or brown, elliptical- shaped spores with a colourless gelatinous wall, but the habit is different : the perithecia of Sordaria grow singly, those of Hypo- copra are combined in a stroma, the only genus in this group that grows in this manner. Podospora includes those species in which the dark-coloured spores have one or more colourless gelatinous appendages. De- litschia and Sporormia have variously septate spores, and as this character has been always recognized as of generic importance, no change has beeen made in these genera. Following Winter's arrangement for the genera with simple spores — Hypocopra stercoraria Sacc. [Spharia stercoraria Sow.) becomes Sordaria stercoraria A. L. Sm. H. scatigena Sacc. {Sph. scatigena B. & Br.) becomes Sordaria scatigena A. L. Sm. H. vesticola Sacc. [Sph. vesticola B. & Br.) becomes Sordaria vesticola A. L. Sm. Sordaria Carhonaria Sacc. [Sph. Carbonaria Plowr.) becomes Podospora carbonaria A. L. Sm. : the brown spores have a persistent small colourless appendage. S. caudata Sacc. (Sph. caudata Curr.) becomes Podosjmra caudata A. L. Sm. S. sparganicola Bucknall. becomes Podospora sparga}iicola A. L. Sm. While preparing the Hyphomycetes for exhibition, I found that the name incequalis, proposed by Cooke & Massee for a species of Oospora, was already occupied by 0. inceqiialis Sacc. & Vogl. {Torula incequalis Corda). I therefore propose to call this plant 0. Masseei. BIBLIOGBAPHICAL NOTES. XIII. — " The Rarest Typographic Product of Linnaeus." [Herr von Flatt has lately published in the Botanisches Centrat- blatt (Bd. Ixvi. (1896), 216-222) an interesting article on two suppressed pages of the first edition of Linnaeus's Species Plantarum, entitled ** Das seltenste typographische Product Linne's." The fact was previously known, for a note to that effect was written by Mr. W. Carruthers in the example cited at the end of this note. The special interest attaching to Herr von Flatt' s notice is, that he gives facsimile reproductions of the suppressed pages ; he has, however, drawn some erroneous inferences. The following is a shortened translation of his article, to which I have appended a few remarks. — B. Daydon Jackson.] Assuredly many botanists have handled the first edition of the Species Plantarum since its first appearance, but up to the present
