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.

AGARICACEAE, Fries.

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.

LEUCOSPORAE.

Marasmius. Tough, drying up and reviving when moistened; gills often connected by veins.

+++ Gills decurrent.

Lactarius. Gills and flesh exuding milk when broken. (In some sp. the gills are adnate.)

Hygrophorus. Gills thick at the base, edge acute, rather waxy, often branched; pileus often hygrophanous. (In some sp. the gills are adnate or even free.)

Clitocybe. Gills thin, pliant, sometimes powdered with the spores; stem fibrous outside.

Omphalia. Gills thin, pliant, stem cartilaginous outside.

Pleurotus. Growing on wood. Stem lateral or excentric when present.

Cantharellus. Gills narrow, edge thick, rather waxy, forking.

Arrhenia. Gills reduced to very slight wrinkles or veins.

Nyctalis. Gills thick, edge blunt. Parasitic on fungi, or among dead leaves, &c.

** Tenaces. Coriaceous, corky, or woody, persistent, rigid when dry.

Lentinus. Pileus coriaceous; gills decurrent, edge toothed or eroded.

Panus. Pileus coriaceous; gills decurrent, edge quite entire.

Xerotus. Pileus coriaceous; gills forking, edge thick.

Lenzites. Horizontal, sessile, woody or corky; gills radiating from behind.

II. Schizophyllae.
Margin of gills split open.

Abbreviations used.

Cm. = centimetres; compr. = compressed; decur. = decurrent; depr. = depressed; exp. = expanded; g. = gills; hygr. = hygrophanous; infundib. = infundibuliform; mm. = millimetres; p. = pileus; s. = stem; sp. = spores; umb. = umbonate; umbil. = umbilicate.

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.

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.)

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.

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."

If you do not charge anything for copies of this eBook, complying with the trademark license is very easy. You may use this eBook for nearly any purpose such as creation of derivative works, reports, performances and research.

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable effort to identify, do copyright research on, transcribe and proofread works not protected by U.S. copyright law in creating the Project Gutenberg™ collection. Despite these efforts, Project Gutenberg™ electronic works, and the medium on which they may be stored, may contain “Defects,” such as, but not limited to, incomplete, inaccurate or corrupt data, transcription errors, a copyright or other intellectual property infringement, a defective or damaged disk or other medium, a computer virus, or computer codes that damage or cannot be read by your equipment.

1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the “Right of Replacement or Refund” described in paragraph 1.F.3, the Project Gutenberg Literary Archive Foundation, the owner of the Project Gutenberg™ trademark, and any other party distributing a Project Gutenberg™ electronic work under this agreement, disclaim all liability to you for damages, costs and expenses, including legal fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH DAMAGE.

LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a defect in this electronic work within 90 days of receiving it, you can receive a refund of the money (if any) you paid for it by sending a written explanation to the person you received the work from. If you received the work on a physical medium, you must return the medium with your written explanation. The person or entity that provided you with the defective work may elect to provide a replacement copy in lieu of a refund. If you received the work electronically, the person or entity providing it to you may choose to give you a second opportunity to receive the work electronically in lieu of a refund. If the second copy is also defective, you may demand a refund in writing without further opportunities to fix the problem.

1.F.4. Except for the limited right of replacement or refund set forth in paragraph 1.F.3, this work is provided to you ‘AS-IS’, WITH NO OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.

1.F.5. Some states do not allow disclaimers of certain implied warranties or the exclusion or limitation of certain types of damages. If any disclaimer or limitation set forth in this agreement violates the law of the state applicable to this agreement, the agreement shall be interpreted to make the maximum disclaimer or limitation permitted by the applicable state law. The invalidity or unenforceability of any provision of this agreement shall not void the remaining provisions.

1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the trademark owner, any agent or employee of the Foundation, anyone providing copies of Project Gutenberg™ electronic works in accordance with this agreement, and any volunteers associated with the production, promotion and distribution of Project Gutenberg™ electronic works, harmless from all liability, costs and expenses, including legal fees, that arise directly or indirectly from any of the following which you do or cause to occur: (a) distribution of this or any Project Gutenberg™ work, (b) alteration, modification, or additions or deletions to any Project Gutenberg™ work, and (c) any Defect you cause.

Section 2. Information about the Mission of Project Gutenberg™

Project Gutenberg™ is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.

Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg™’s goals and ensuring that the Project Gutenberg™ collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg™ and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 3. Information about the Project Gutenberg Literary Archive Foundation

The Project Gutenberg Literary Archive Foundation is a non-profit 501(c)(3) educational corporation organized under the laws of the state of Mississippi and granted tax exempt status by the Internal Revenue Service. The Foundation’s EIN or federal tax identification number is 64-6221541. Contributions to the Project Gutenberg Literary Archive Foundation are tax deductible to the full extent permitted by U.S. federal laws and your state’s laws.

The Foundation’s business office is located at 809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up to date contact information can be found at the Foundation’s website and official page at www.gutenberg.org/contact

Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation

Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.

The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.

International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.

Section 5. General Information About Project Gutenberg™ electronic works

Professor Michael S. Hart was the originator of the Project Gutenberg™ concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg™ eBooks with only a loose network of volunteer support.

Project Gutenberg™ eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.

Most people start at our website which has the main PG search facility: www.gutenberg.org.

This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
