TAB. CCCCVIII. 



Contains figures of other varieties of Ag. virosus, having 

 the lamellae or gills paler than usual. No. 1. has the annulus 

 or ruffle large. No. 2. with a thick stem and the annulus 

 darker on the side towards the gills, pileus with an umbo or 

 rising in the middle. No. 3. a somewhat bulbous lonff- 

 rooted variety : I have seen the root with fibres an inch long. 

 No. 4. aflat-topped variety. No. 5. with the pileus incurved 

 to the large annulus. ; No. 6. shrivelling as they do in slow 

 drying, though in quick drying they sometimes crack or turn 

 up. I gathered this sort in Kensington Gardens, in June 

 1795, and August, 1796; and I observed some boys gathering 

 them for Champignons or Ag. orcades, but advised them to 

 throw them away, lest they should eat them. In the Green 

 Park, about the same time, a nursery-maid, seeing me a 

 little curious, asked me about some of those fiffured in this 

 plate. I gave her, and two little ones that were with her, 

 the same advice; she was, however, confident in her own 

 opinion, that they Avere good to eat; but I had the satisfaction 

 to see her throw them away when at a distance from me*.

A.FTER treating of the Fungi poisonous to the human con- 

 stitution, it may not be improper to say something of those 

 that affect vegetables and our food. This present has been 

 long a troublesome parasite in many places, and has been 

 the cause of much loss as to the trees which it attacks, as well 

 as in expensive and useless attempts to get rid of it. I think, 

 however, its very nature, like the dry rot, bespeaks an easy 

 cure, but easy cures do not always gain the confidence due 

 to them. I did not dare to give an easy receipt for the cure 

 of the dry-rot, till it was proved to be a good one by Lord 



* Every season seems to furnish us with cogent reasons for more particularly 

 attending to this tribe of poisonous Fungi, as well in other countries as in this ; a 

 whole family in France died with eating some such Champignons as these a year or 

 two ago. See Phil. Mag. vol. 3 1. p. 395.
