gustis arcuato-decurrentibus distantibus albis ; interstitiis venosis. 

 King^s ClifFe. On the ground in woods where there is little un- 

 derwood. Oct. 6, 1840. 



Pileus 2 inches broad^ at first very strongly umbonate, obco- 

 nical, at length flat or even depressed, with the border flexuous, 

 not the least involute in any stage of growth; disc fuliginous, very 

 minutely virgate; border whitish, with dingy sodden spots. It is not 

 viscid, though it has a damp appearance. Stem 1 inch high, f ths 

 of an inch thick, or 2 inches high and §ths of an inch thick; some- 

 times short and stout, sometimes much elongated, dingy like the 

 pileus, clothed with matted down which reaches up to the base of 

 the gills, often smooth at the base, which is buried amongst leaves 

 and attached to them by the downy mycelium ; solid, mottled 

 within, slightly discoloured beneath the cuticle. Gills very di- 

 stant, decurrent, white, interstices more or less veined. Spores 

 elliptic ; spicules long. 



Much eaten by slugs. This is certainly quite a distinct spe- 

 cies from Ag. camarophyllus, to which Fries refers it. The gills 

 are by no means thick ; they are narrow and white, not glaucous. 

 The whole in moist weather is like a sponge sodden with water. 

 It does not appear to me to have any affinity with Hygrophorus. 

 When young, the pileus has quite the form of Gomphidius gluti- 

 nosus.

 Oct. 7, 1840. 



Pileus 3 inches broad, fleshy, plane, with the border convex 

 and involute, opake-white, smooth, with a few dirty ochraceous 

 patches ; flesh white, brittle. Stem 2 inches high, about 1 inch 

 thick, blunt, opake-white with a slight tinge of fawn-colour. 

 Gills crowded, decurrent, white with a reddish tinge, somewhat 

 forked at the base. Smell strong but not unpleasant.

 The specimens referred formerly to Ag. Vaillantii belong to this 

 species; at least they are identical with what Madame Libert 

 has published as the plant of Persoon, and her authority is con- 

 fessedly very great. My specimens have the gills as in Ag. Vail- 

 lantii, and by no means merely adnexed ; but this accords with 

 the observation of Fries in the ^ Systema Mycologicum.' We 

 must therefore still depend for Ag. Vaillantii, as entitled to a 

 place in our Flora, on Withering. 



*267. Ag. umbelliferus, L. The beautiful yellow variety re- 

 presented by Holmskiold, vol. ii. t. 34, occurred at Capel Curig 

 in 1842, and' Mr. Salwey has sent it to me from Llyn Howel. 



*268. Ag. stellatus, Fr. On bramble, Oct. 7, 1840, Wo- 

 thorpe. I have also received it from the west of England from 

 Mr. Salwey.
