ters^ as given by Mr. Berkeley, are not repeated in the 

 present volume, but the page at which the description may 

 be found in Vol. I. is in every instance given. The 

 characters of all new genera and sub-genera are given in 

 full, and the minor sectional characters as given in the 

 present volume will be found to aid greatly in the deter- 

 mination of species ; in fact, as Vol. II. contains more 

 specific descriptions than Vol. I., as well as a complete list 

 of all the higher fungi recorded for Britain up to date, it is 

 obvious that Vol. II. should be used for the determination 

 of species and Vol. I. as a supplement.
