xxx INTRODUCTION. 



feci: ftate, has coft much time and application, and which will accompany 

 this work, when the remaining part of the Appendix is compleated. 

 For there are yet many fubjedts in my poffeflion, which I do "not think 

 fit yet to publifh, becauie I have not feen them in all their different ftages 

 and appearances j but fhall omit no opportunity of obferving them, till 

 I attain a more perfect investigation. 



Agarics, Boletuffes, and fuch other Fungi as grow on the ground, are 

 to be fought for in foils conlifting chiefly of vegetable mould, particularly 

 in low, moift, and fhady woods, in meadows and pafture grounds, under 

 hedges, and about old wood yards. In gravelly or clay foils, of what- 

 ever afpecl or lituation, few fpecies are to be found ; and I never faw 

 them grow plentifully in calcarious foils. 



The parafitic Fungi are to be found in low and moift fituations, near 

 brooks or rivulets, on pieces of broken trees in a ftate of decay. The 

 fpecies of woods on which the feeds of thefe plants more freely vegetate, 

 are Hafle, Birch, Alder, Elder, Maple, Elm, Poplar, the various fpecies 



of Sallow, Pear Tree, Cherry Tree, and Fruit Trees in general. 



Descriptions, with accurate figures, of which, as well as all other 

 Britiih Trees, may be fee.n in Evelyn's Sylva, with notes and improve- 

 ments, by Dr. Hunter, M- D. F. R. S. printed in 4to, at York, 

 1776. A work which fhould be carefully perufed by all thofe who 

 deal in Timber, and by every Gentleman and .Landholder, who has the 

 Profperity of his Plantations at heart. 



In regard to the Authors who have written on Funguffes, and 

 illuftrated their works with figures, the fir ft of any note, which I have 

 feen, is Francis Van Sterbeck, who in his Tbeatrum Fungorwn, firft 

 printed at Antwerp, in 1654, in 4to. has on thirty- two plates given 

 about three hundred figures, with defcriptions in the Dutch language: 

 His figures are pretty good, but in fome the Generic Characters are not 

 properly attended to bv the engraver. I have an Original Painted Copv
