INTRODUCTION. 



Tab. 53. Agaricus a : liar is. Since the publication of this, I find that 

 what I took for hairs on the margin were not fuch, for, on examining 

 other fpecimens afterwards, under the fame appearance, I found, by means 

 of a fpy-glafs, that the ciliation did not confift of hairs, but of the black 

 feeds of the plant, which had Hid down from the gills, by means of a 

 glutin, in which they were fufpended, in an even line, all round the ex- 

 treme verge of the pileus. I was led to this dilcovery, by finding the 

 plant frequently without the ciliation, and but very rarely with it. 



Tab. 45. Agaricus ft riatus. I have reafons, drawn from obfervations 

 lately made, to fuppofe that the fmall plant, with grains on the furface, 

 figured on this plate, is a proper fpecies, diftincl: from the Agaricus Jlriatus. 



Tab. 72. Boletus alius. Since the drawing of that figure, I find that 

 the red colour on the bafe, and the curling of the margin, are circum- 

 flances almoft peculiar to the young plant ; for at its full growth the red 

 nearly vanifhes, and, as the margin extends, it becomes more fmooth and 

 entire. The pores are fometimes gently tinged with red. I make no 

 doubt of its being the fame fpecies with Bulliard's Boletus falicinus.

Tab. 122. Sphceria bombardica. In the place where this plant takes 

 root, it continues for a fucceffion of feafons. The firft winter forms a (in- 

 gle fbratum, fucceeding feafons form others upon that, till it becomes ag- 

 gregate. In the firft ftate, I defcribed and figured it; I believe that 

 Lightfoot and Relhan faw it in the laft. 



Tab. 129. Sphceria digit at a. Some of my botanical acquaintance do 

 not agree with me in fuppofing the Sphceria digitata and hypoxylon to be 

 varieties of the fame fpecies ; and I have received fpecimens of a fhape 

 different from any of thofe reprefented on my plate. The plant is a per- 

 fect proteus ; and I have not been able, after the ftricteit. inquiry, to dis- 

 cover any certain criterion of diftimSion between the two fuppofed fpecies.
