X PREFACE. 



its sub-geuus Togiiiia. But," adds Fries, " I am un- 

 willing to found a new sub-genus from a single species/' 

 A. aureus is, however, not the only species which agrees 

 with Lepiota and FsalUota ; all the first eight terrestrial 

 species of Pholiota rightly belong to Toyaria. Phiteolus 

 corresponds with Hiatula and Pluteus. Fries, Cooke, and 

 Stevenson have misplaced this sub-genus in putting it next 

 to Galcra ; it should, as its structure and habit show, 

 be placed between Totjaria and Pholiota, in the posi- 

 tion of Hiatula amongst the white-spored, and Pluteus 

 among the rosy-spored Agarics. Inocybe was formerly 

 included in Hebeloma. Tubaria contains species formerly 

 included in Navcoria and Galeru. Amongst the purple- 

 spored Agarics, the sub-genera Chitonia and P'llosace are 

 new since the publication of the Outlines. Strop// aria was 

 formerly included in Psalliota. 



It has not been thought desirable to make more exten- 

 sive alterations in sequence or the establishment of new 

 genera in the present volume. Nearly all the descriptive 

 work is that of Elias Fries, and this new edition of 

 Berkeley's Outlines fairly represents Fries' views and con- 

 clusions at the time of his death. 



As Mr. Berkeley's original work gives descriptions of all 

 the larger British fungi, including puft-balls, truffles, 

 pezizae, &c., the recent additions to the lists of these fungi 

 have been made good in the present volume. 



No references to published illustrations of fungi are 

 given to the first 1388 species — i.e., to the end of Ayaricini 

 at p. 273 — as nearly all these fungi are illustrated in colour 

 in Illustrations of British Fungi by Dr. M. C. Cooke. For 

 the succeeding species, references to published plates are 

 given.
