CORRECTIONS.

=Armillaria focalis=, Fr. (p. 14), should be placed in the genus Lepiota, following L. naucina, Fr., p. 11.

=Cortinarius subsimilis=, Fr. (p. 183), should be placed under the section "Gills olive or smoky," p. 183.

=Cortinarius Karstenii=, Sacc. and Syd. This name should replace Cort. olivascens, Karsten, p. 191. There is an earlier Cort. olivascens, Fries, p. 183.

BIBLIOGRAPHY.

The following short list of comparatively recent works indicates where more detailed descriptions and illustrations of European Agarics may be consulted.

GENERAL WORKS, CONTAINING DESCRIPTIONS OF THE AGARICS OF MORE THAN ONE COUNTRY.

Hymenomycetes Europaei, sive Epicriseos Systematis Mycologici; Elias Fries. Ed. II. Upsala, 1876.

(Although not of recent date, this work cannot be omitted, inasmuch as it embodies the experience of over fifty years of continuous observation on the part of the author, and is the sheet-anchor of the present generation of mycologists. Written in Latin.)

Sylloge Fungorum omnium hucusque cognitorum; P. A. Saccardo. Vol. V. Padua, 1887.

(Contains descriptions of all European Agarics up to date of publication. Later discoveries are contained in various supplements. Written in Latin.)

Rysslands, Finlands och den Skandinaviska halfoens Hattsvampar; P. A. Karsten. Helsingfors, 1879.

(Descriptions of Russian, Finnish and Scandinavian Agarics, in Swedish. It is in this work where Fries' subgenera, as Amanita, etc. are first raised to specific rank. Written in Swedish.)

Die Pilze Deutschlands, Oesterreichs und der Schweiz; Georg Winter. Leipzig, 1884.

(This forms the first volume of Rabenhorst's 'Kryptogamen-Flora von Deutschland, Oesterreich und der Schweiz,' and contains along with other fungi, descriptions of the Agarics of Germany, Austria and Switzerland, in German.)

Flore Mycologique de la France et des Pays limitrophes; Lucien Quelet. Paris, 1888.

(This is undoubtedly the best and latest work containing detailed descriptions of the Basidiomycetes of Central and Western Europe. The systematic arrangement is new and somewhat perplexing, and the index is a terror. Written in French.)

GREAT BRITAIN.

Illustrations of British Fungi; M. C. Cooke. London, 1881-1891.

(This is by far the most important, and at the same time the most comprehensive series of coloured figures of Agarics ever published in any country, including 1199 plates.)

Handbook of British Fungi; M. C. Cooke. London, 1883.

(This work is a second edition of Cooke's 'Handbook of British Fungi,' London, 1871, and contains descriptions of all the figures given in the 'Illustrations of British Fungi.')

British Fungus-Flora; Geo. Massee. 4 vols. London, 1892-1895.

(The first three volumes include all the British Agarics up to date of publication. In addition to a diagnosis of each species, critical notes by Fries, Berkeley, Cooke and other mycologists are appended.)
