* moft of that genus. Upon other fpecimens gathered about the

* day or two. At length fome of them having divefted them-

* fcription of his Chermes graminis. This fpecies is faid by him 
“to live on the ira flexuofa, on which I have not yet found it, 
* though I fearched for it particularly when thefe infects were

“There is no doubt therefore that the Chermes graminis lives upon 
* the plant in queftion, and is the caufe of its producing thefe 
leafy utricu/t inftead of ftalks and flowers. In the fame manner the 
* Chermes abietis caufes the tubercles found on fome branches of the 
* fpruce fir inftead of young fhoots and leaves; and as the trees 
* upon which thefe tubercles are found are not, upon that ac- 
ned varieties of the fpruce fir, fo the plants that have 
* fome, or even the whole, of their ftalks and leaves contracted

‘ into {hort bunches, ought not to be confidered as varieties of the 
6 Funcus articulatus." 
.** Mr. Lightfoot mentions in the Fra Scotica that he does not 
«remember to have found the Agaricus deliciofus in Britains: It 
* grows however plentifully in the fir plantations here, about the 
* beginning of October, and will therefore it is hoped have a place 
& in every future Flora Scotica*.”” 
"^ * Dr. Smith, P. L. S. found this Agaricus in Rivelftone wood near Edinburgh, 1782, 
and on the Marchionefs of Rockingham's lawn at Hillingdon, Middlefex, under fome fir 
trees, in OG. 1795. Mr. Hudfon mentions it as growing near Guildford.
