PREFACE. 



The engravings are either reductions from the 

 large drawings used at the lectures, or from others 

 made from nature since. They are all (with the 

 exception of one or two which it was necessary should 

 be copies) original, and from living examples. 



We hope the illustrations will be useful ; we 

 believe they are correct j they show what we have 

 seen, or think we have seen. 



Excellent preparations for the microscope of the 

 fungi mentioned in these pages may be purchased, at 

 moderate prices, from the Eev. J. E. Vize, M.A., 

 Forden, Welshpool. 



Our thanks are due for assistance to our friends 

 Mr. Chas. B. Plowright, M.R.C.S., King's Lynn; 

 and to Mr. A. Stephen Wilson of North Kinmundy, 

 Summerhill, Aberdeen. 



Most of the original camera-lucida drawings, with 

 many of the actual examples, and a large series of 

 microscopic preparations used at the lectures and for 

 this work, are now in the department of Botany, 

 British Museum (Natural History), South Kensington.
