Tn the preparation of the following list of Fungi, nearly all the British, 

 and many of the foreign authorities have been consulted. For the 

 means of doing this I am principally indebted to Joseph Dickinson, 

 Esq. M.D. F.K.S., who has kindly allowed me to retain in my possession 

 for tliree years, many rare and valuable works from his extensive 

 library. Amongst these I may mention Sowerby's " British Fungi," 

 3 vols, folio, Bolton's " History of Funguses, growing about Halifax," 

 4to., Batsch's " Elenohus Fungorum," 4to., GreviUe's " Scottish Crypto- 

 gamic Flora," 6 vols. 8vo., Stunn's " Deutschlands Flora," 34 parts, &c. 

 The libraiy at the Athenaeum has enabled me to refer to Schoeflfer's 

 work ; and my thanks are due to the Committee of the liverpool Free 

 Public Librai-y for pm-cbasing at my suggestion the very valuable work 

 by Bulliard, " Hist, des Charapigu. de la France," 5 vols. 4to. The names 

 of several friends who have assisted me \rith specimens, &c., will 

 appear in the list.
