PREFACE. 



Thirty' years have passed since the first edition of the 

 Outlines of British Fungoloyy was published. During this 

 time the species of fungi known to be British have more 

 than doubled in number. Not only new species, but many 

 new genera of fungi have been added to the British lists. 

 Mr. Berkeley, in the first edition of this work_, was only 

 able to partially avail himself of Fries' writings. In 1876 

 Fries published his latest work on the higher fungi, 

 or Hymenomyeetes, under the name of Hijmeiiomycetes 

 Eu7'opcei sive Epicriseos Sijstematis Mycoloyici. In that 

 work Fries reviewed the whole family, added several new 

 sub-genera to the genus Agaricus^ as well as new genera 

 elsewhere, and abolished as spurious several genera 

 originally established, and incorporated by Mr. Berkeley in 

 his Outlines. 



The additions and alterations being so extensive, the 

 publishers determined upon the issue of a new edition, 

 which should bring the record of the larger fungi up to 

 the present state of knowledge, and the first idea was to 

 publish a supplement with the names and descriptions of 

 the new British species. On making this attempt, it was 

 found to be thoroughly impracticable, owing to name 

 alterations and to the re-arrangement of many groups of
