To my friend Dr M. C. Cooke, to whom in matters Mycological I cannot sufficiently express my indebtedness; I have much pleasure in dedicating this attempt to introduce to British Mycologists, the Agarics of European countries.

PREFACE.

Observations extending over a period of twenty-five years, made at Fungus Forays and kindred meetings where Mycologists assemble together, has led to the conviction that familiarity with the Fungi and literature pertaining thereto, of one country only, leads to a false impression as to the significance of the term 'species.'

It conveys the idea that species are much more sharply defined than proves to be the case, when the entire Fungus Flora of Europe is included.

In all large genera common to European countries, the continental species can be sandwiched between British species. Even in large genera there are as a rule not more than eight or ten primary differentiating specific characters present, and it is the constant correlation of two or three of those primary characters that constitute a species, as understood at the present day.

If two British species are characterised respectively by the marks 1, 2, and 3, 4, then we find that two continental species belonging to the same genus will be indicated by the characters 1, 3, and 2, 4, respectively.

Primary specific characters should include only those features that are constant, and not materially modified by geographical or exceptional local conditions as to environment, etc., and such alone should constitute a specific diagnosis. Trivial or local characteristics should follow the essential diagnosis as a rider.

With the introduction of characters due to local conditions, a description ceases to be a specific diagnosis in the proper sense, and is merely a description of a certain state of a species occurring under a given set of conditions. Such, however, is too frequently the nature of so-called specific characters given in local Floras.

A lengthy and laboured description suggests lack of power to grip essentials on the part of the compiler, and does not as a rule facilitate the recognition of the species intended.

The idea of this work is to give the essential characters of each species as presented by pileus, gills, stem and spores respectively. This, however, owing to the views of some authors as to the predominant value of one feature to the exclusion of others, has not always been possible. For this reason the species of Britzelmayr are not included, as his descriptions, even when aided by what are presumably intended as figures, could not in many instances be construed into an intelligible diagnosis.

In Cooke and Quélet's Clavis Synoptica Hymenomycetum Europaeorum (1878), 1943 species of Agarics are recorded as European, and of these 939 are given as British. The present work includes descriptions of 2750 European species, of which 1553 are British, a number considerably in excess of that recorded for the species of any other European country.

The species indicated by brackets have not been recorded as British.

Kew, June, 1902.

Hymenium covering the entire surface of radiating lamellae or gills. Spores one-celled.

Primary divisions of the Agaricaceae depend on the colour of the spores as seen in the mass, when deposited on an opaque substance; and not as seen under the microscope by transmitted light.

I. Leucosporae.

Spores white. In some cases with a tinge of yellow or pink. In some species of Russula the spores are clear ochre, but such species belong obviously to Russula notwithstanding.
II. Chlorosporae.

Spores clear green or bluish-green.
III. Rhodosporae.

Spores salmon-colour or pink.
IV. Ochrosporae.

Spores ochraceous or rust-colour.
V. Melanosporae.

Spores black, blackish-brown, or black with a purple tinge.

CORRECTIONS. — BIBLIOGRAPHY. — INDEX.

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.

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.)

(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 Quélet. 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.)

France.

Les Hyménomycètes, ou description de tous les Champignons (Fungi) qui croissent en France; C. C. Gillet. Alençon, 1874-1902.

(Contains descriptions of all known French Hymenomycetes, illustrated by 1907 coloured plates, 8vo. In French.)

Figures peintes de Champignons de la France; L. Lucand, 1884-1889.

(A series of beautifully executed figures, mostly Agarics, on 425 plates 4to size. The number of copies was in the first instance very limited, and prepared only for subscribers. No descriptive text; names and synonyms given on the plates.)

Germany.

Die Pilze Schlesiens; J. Schroeter. Breslau, 1889.

(This work constitutes Vol. III. part I. of Cohn's Kryptogamen-Flora von Schlesien, and contains full descriptions of all Agarics indigenous to Silesia. In German.)

Sweden.

Icones selectae Hymenomycetum nondum delineatorum; Elias Fries. Stockholm, 1867.

(An indispensable work to the student of the Agaricaceae, containing descriptions and coloured figures of numerous species on 200 4to. plates. Written in Latin.)

Austria.

Fungi Tridentini novi, vel nondum delineati, descripti, et iconibus illustrati; J. Bresadola. Tridenti, 1881-.

(This work contains very full descriptions of new or critical species, mostly Agarics, which are illustrated in colour on 217 plates, 8vo. Written in Latin. This work appears in parts at irregular intervals, and is still going on.)

Italy.

Flore Mycologique Illustrée. Les Champignons des Alpes-Maritimes; J. B. Barla. Nice, 1888-1892.

(An excellent work, 4to size, containing coloured illustrations of new, rare, or critical Agarics on 64 plates. In French.)

Holland.

Révision des Champignons tant supérieurs qu'inférieurs trouvés jusqu'à ce jour dans les Pays-Bas; C. A. J. A. Oudemans. Amsterdam, 1893.

(Vol. I. of this work contains descriptions and valuable original comments of all the Hymenomycetes, Gasteromycetes, and Hypodermei met with in Holland. Written in French.)

CAMBRIDGE: PRINTED BY J. AND C. F. CLAY, AT THE UNIVERSITY PRESS.

DUCKWORTH & CO.

IMPORTANT BOTANICAL WORKS.

JACKSON, B. DAYDON.

A Glossary of Botanic Terms, with their derivation and accent. By Benjamin Daydon Jackson, Secretary of the Linnean Society of London. Crown 8vo. 6s. net.

Athenæum.—"Every Botanist will praise this work."

Gardeners' Chronicle.—"A much needed glossary. Should find a place in every garden library."

Journal of Botany.—"Mr Jackson has supplied what was wanting."

Nature.—"Exceedingly valuable."

Science Gossip.—"No botanist can afford to dispense with this work."

PERCIVAL, JOHN.

Agricultural Botany: Theoretical and Practical. By John Percival, M.A., F.L.S., Professor of Botany at the South-Eastern Agricultural College, Wye. Crown 8vo, with 265 Illustrations by the Author. 7s. 6d. net.

Second Edition. Ready now.

Incorporated in the text are 265 illustrations, and over three hundred experiments, which specially enhance the value of the book for schools and colleges where botany, agriculture, and horticulture are taught.

Nature.—"We have no hesitation in recommending it as the elementary handbook for the agricultural student. The chapters on weeds and on diseases of farm-plants are distinctly better than those in any previous English works dealing with agricultural botany."

Journal of Education.—"A book which supplies what has for a long time been felt as a serious want in the literature of agricultural textbooks.... The book could hardly have been better."

MASSEE, GEORGE.

A Text-Book of Plant Diseases, caused by Cryptogamic Parasites. By George Massee, F.L.S., Mycologist and Principal Assistant, Royal Herbarium, Kew. With 92 Illustrations, drawn from Nature by the Author. Crown 8vo. 5s. net.

Literature.—"The book deserves to become the leading English textbook on the subject."

Farmers' Gazette.—"The manual which Messrs Duckworth have so attractively brought out for Mr Massee is one of the best of its kind that has yet appeared."

MOYLE ROGERS, THE REV. W.

A Hand-book of British Rubi. By the Rev. W. Moyle Rogers, F.L.S. Demy 8vo. 5s. net.

DUCKWORTH & CO.
3 HENRIETTA STREET, COVENT GARDEN.

Transcriber's Notes.

The printer used raised dots for the decimal point; they were changed to periods.

The dagger symbol was used in the keys; I changed them to the plus sign.

There are many inconsistencies in the way words are abbreviated, the hyphenation, the Latin word endings and the capitalization of names, as well as the spelling in general; except where noted below, I left them as is.

Changed "subq." to "subg." on page 11: "sp. subg. 6-7."

Changed comma to period after "rufous" on page 23: "p. tinged rufous."

Changed "peristently" to "persistently" on page 24: "persistently reddish flesh colour."

Added missing period after "g" on page 30: "g. deep ochraceous."

Sometimes the abbreviation "sp." is missing when the spores are described, such as page 31; I left them as is. Similarly, the abbreviation "P." is sometimes missing when the pileus is described as on page 50. I also left this as is.

Added period after "var" on page 36: "var. violacea."

Changed "striata" to "striate" on page 42: "striate at paler margin."

Changed comma to period in entry for haematopoda on page 45: "Caespitose."

Changed "mik" to "milk" on page 45: "giving out milk when broken."

Changed period to comma after "lax" on page 49: "lax, campan. then exp."

Changed "hariolarum" to "hariolorum" on page 51: "Differs from C. hariolorum."

Although it appears that "P." should be after "Acrid.", I left it as is on page 56 in the entry for M. urens.

Changed "palllid" to "pallid" on page 56: "pallid then rufescent."

The upper limit on the size of the pileus for M. plancus is missing on page 57. I inserted an ellipsis as a placeholder.

Added a period after "P" on page 57: (varicosus) "P. 1.5-3 cm."

Changed "sub-umb." to "subumb." on page 58: "subumb. lilac-brown."

The spore size for M. fuscopurpureus on page 57 was left as "4-3" even though that must be in error.

Changed semi-colon to comma on page 72: "with white points upwards, 3-5 cm."

The authority for M. xerotoides was left as "Tr.", although "Fr." might have been intended.

Replaced "]" with ")" on page 79: "(= Clitocybe Marzuolus, Bres.)."

The authority for C. hirneola var. undulata was missing on page 80; I inserted "——." as a placeholder.

Inserted period after "s" on page 83: "s. 7-10 cm."

Changed "floccossly" to "floccosely" on page 85: "floccosely villose."

Changed "yelllow" to "yellow" on page 100: "white then livid yellow."

There are two entries for Cantharellus tubaeformis var. lutescens on page 107. Although these are almost identical, I kept them both.

Changed comma to period on page 108: "plano-infundib."

Changed "p." to "P." on page 112: "P. thin, subdimidiate."

Changed "Quelet" to "Quélet" on page 116: "Quélet says."

Removed extra period after "then" on page 126: "P. campan. then exp."

Changed "D.C." to "D. C." on page 140: "lamellirugis, D. C."

Changed "verdegris" to "verdigris" on page 149: "tinged verdigris at base." Also on page 175: "verdigris green."

Removed replaced hyphen with space on page 149: "apex naked."

Change "squarrosula" to "squarrulosa" on page 149: "squarrulosa, Karst."

Inserted period after "var" on page 156: "var. major, B. and Br."

Removed extra period after "campanulato" on page 161: "P. campanulato-exp."

Inserted period after "g" on page 168: "g. slightly sinuate."

Changed "Hypholama" to "Hypholoma" on page 175: "Habit of Hypholoma fasciculare."

Changed "Sub-genera" to "Subgenera" on page 177: "Key to the Subgenera."

Changed "sub-bulbous" to "subbulbous" on page 177 for consistency: "subbulbous base." Also on page 197: "subbulbous base."

Changed "fucescent" to "fuscescent" on page 188: "fuscescent with a grey bloom."

Sometimes, as on page 208, the Micro character is included with the spore size. I left these where they occurred in the original.

Inserted comma after "free" on page 230: "g. free, white then black."

Removed extra period after "in" on page 236: "in p. being globose."

Inserted periods after "Jacobasch" and ")" on page 238 for consistency: "Jacobasch. (= Cop. intermedius Gill.)."

Changed "+" to "×" on page 240: (Pallassii) "sp. 12 × 4."

Added missing ")" to close paragraph on page 246: "British Fungi.')"

Changed "caeseriata" to "caesariata" on page 251: "caesariata (Ino.), 154."

Changed "cöopertus" to "coöpertus" on page 253: "coöpertus (Copr.), 237."

Changed "16" to "86" on page 256: "flaccida (Cli.), 86."

Moved period inside parentheses on page 256: "ephemerus (Copr.), 237."

Inserted missing page number in Index: "macrocephalus (Copr.), 234."

Changed "Amv." to "Ann." on page 261: "laevis (Ann.), 120."

Left inconsistent capitalization of "Var." and "var."
