As such a rare plant has been found with you, I 
have no doubt but more will be found if looked 
after. You must not depend upon my judgement on 
Fungi, it being but a new study to meas yet. I 
find no author that is to be depended upon, and 
none worse than Mr. H.; and Mr. Lightfoot has so 
very few. Scheffer’s figures, some good and some 
very bad; I know about an half of what is in Hudson 
to be sure of. I mean Agarici, and many he has not 
got. If you go to the Highlands of Scotland, I have 
not any doubt but you will find some new plants. I 
have received some from thence since Mr. Lightfoot’s 
publication. I am now on the top study of Fungi; 
should be glad of all you can send me, and I will 
return you what I make of them. I received some 
from Mr. Crowe: I am not able to make them all 
out as yet. You are wrong in your doubts about the 
Elymus arenarius—I have seen the Elymus philadel- 
phicus at Sir Joseph Banks’s. I have a specimen 
of Elatine Alsinastrum, but did not find it myself. 
I shall ask Sir Joseph Banks about it: he is the 
only man that can inform me of it. The Arbutus 
Andrachne that sold at Dr. Fothergill’s for fifty-one 
guineas was not half so large as that at Chelsea. I 
found a few days ago the Boletus perennis, which 
I had never seen before. Have you ever seen the 
Lycoperdon pedunculatum ? 1 want it much. 
I am, Sir, your very humble servant, 
James Dickson.
