J_ HIS Specie?, (the same as the one cited above) may be. 

 equally noxious, under every form in which it may appear. 

 Mr. Dickson, the well-known and excellent Cryptogamist, 

 brought me many specimens, which my experience convinces 

 me belong to this species, and Avhich were the same sort that 

 had fatal effects at Mitcham upon those who cat of them. 

 Of these I haAC secured drawings, considering it of much 

 importance to make the species well known, and I shall there- 

 fore here publish an arrangement of its varieties. I know 

 not how some of them could be taken for Champignons, or 

 Avhat are commonly called Fairy Ring Funguses, which has 

 got them the trivial nameof 0;*Cffc?C5, (not one of the most for- 

 tunate as many Agarics form rings; and Mr. Bolton, who 

 I believe Avas the first to giAe it this title, has been still more 

 vinfortunate in his figure, which is as much like the poisonous 

 as the edible one; and if that figure had been referred to, 

 might account for the fatal mistakes.) I should think it pos- 

 sible that the English term Scotch Bonnets, the name under 

 Avhich the Fairy Ring Fungus appears in Ray's Synopsis, 

 derived from the form of the pileus, might also mislead ; but 

 our poisonous Agaric is seldom so formed, and is ahvays 

 nsore brittle than the edible one, and more varied, as I Avill 

 amply shew in detailing the figures. Fig. 1. has something 

 of the shape of the Agaricus Orcades in the pileus, but it has 

 some fuscous seeds on the stem, and is more varied in colour. 

 Fig. 2. 3. 4. 5. and 6. are Aarieties of the same, gathered at 

 Mitcham, on the spot, by Mr. Dickson and the man Avho 

 assisted in gathering those Avhich unhappily proved so fatal. 

 No. 7 . and 8. are some Aarieties sent me from North Wales 

 by the Rev. Hugh Davies, Avho obserAcd that they were like 

 Agaricus semiglobatus, but that the gills Avere generally on a 

 plane Avith the rim of the pileus. No. 9. and 10. are other 

 A'arieties, rather sodden, gathered at Mead Place, having 

 nothing by Avhich it n'.ay be distinguished as belonging to this 



* I thought suc'i a name would operate as a caution, else I do not like new 

 names.
