 seedling chestnuts, &c. I have also found it at Nash Court, 

 near Margate, and at King's Cliffe.

 t. 34. f. 5. This is considered by Fries, to whom it appears 

 known only by Persoon's character, as a state probably of Ag. 

 callochrous, to which indeed it is allied, but, I think, quite di- 

 stinct, and certainly one of the most beautiful species with 

 which I am acquainted. I have seen it in one locality only at 

 King's Cliffe, Sept. and Oct. 1837- Pileus two and a half to 

 three inches broad, at length nearly plane with the margin 

 repand, of a beautiful azure blue ; at first viscid, when dry 

 marked with a few innate indistinct squamiform patches, 

 fleshy, flesh rather firm, not changing to violet when bruised. 

 Gills rather distant, adnate, subdecurrent, obscurely emargi- 

 nate, violet, at length stained with the sporidia. Stem three 

 inches high, half to three quarters inch thick, solid, bulbous 

 of the same colour as the pileus, flbrillose. Smell like that of 

 radishes.

 rotten stumps, Apethorpe and Laxton, Norths, Sept. and 

 Oct. 1837. This species, which is one of considerable interest 

 from its exact analogy with Ag. phlebophorus, Ditm., varies so 

 much in passing to maturity, that till I found the fully ex- 

 panded plant at Laxton, I was in great uncertainty whether 

 it w r ere the plant intended by Persoon. In the younger state 

 the pileus is of a delicate bistre, and it is only in age that it 

 assumes a violet tinge, apparently from the colour of the spores 

 being partly seen through the flesh.
