 real claim to be considered as native, not naturalized, plants 



in this island. I may add that some botanists consider both 



these plants to form only one species. This last is a question 



well worthy of experimental inquiry.

*59. Agaricus fulvus, Bull. Dec. Fl. Fr. vol. ii. p. 186. The 

 form described in the English Flora is that with pallid gills 

 noticed by Retz. The present season has afforded a few spe- 

 cimens in which the gills and inside of the stem were more 

 or less yellow. 



60. Ag. decolor ans, Fr. Syst. Myc. v. i. p. 56. Woods, at 

 King's Cliffe, Sept. 1, 1837. Distinguished from A. alutaceus 

 by its pale sporidia, in consequence of which the gills remain 

 much longer white, so that on an hasty inspection it might be 

 passed over as a form of Ag.furcatus. The inside of the stem, 

 which is thick and spongy, acquires in general a cinereous 

 tinge. It is an esculent species clearly pointed out by Mi- 

 cheli, p. 155. n. 1. 



*61. Ag. grammopodius, Bull. Inserted in the English 

 Flora on the authority of Withering and Purton. I have 

 found it in two fields at Apethorpe, Norths, sometimes form- 

 ing large rings, where it appears every autumn. The descrip- 

 tion given in Eng. Fl. of Ag. nebularis, a species with which 

 I was not at the time of its publication well acquainted, be- 

 longs to the present Agaric. The discovery of the true plant, 

 which is figured by Dr. Greville under the name of Ag. tur- 

 gidus, has cleared up all doubt upon the point. 



62. Ag. unguinosus, Fr. Syst. Myc. v. i. p. 101. Amongst 

 wet grass and moss close to the Spa, King's Cliffe, Oct. 18, 

 1837. 



63 f. Ag. calyptraformis, n. s. Ag. conicus, a. amcenus, 



\ I have not thought it necessaiy to give figures of this or other new or 

 little understood Agarics, as beautiful drawings have been made by Mr. J,
