which appears to have been noticed only by Bolton, occurred abund- 

 antly at King's Cliffe, October 1835. The gills are sprinkled over 

 with short purple hairs, like those on the lip of Orchis fusca, which 

 on the edge are arranged in fascicles. Smell strong, somewhat like 

 that of Ag. sulphureus. Sporidia white. Habit approaching to that 

 of some species of the subgenus Psathyra. 



3. Ag. rubidus, n. s. — Amongst mosses on the mould of a pot con- 

 taining a foreign Polypodium, consisting of peat and sand, in a hot- 

 house at Milton, Northamptonshire, March 1, 1836. 



Pileus ^ inch broad, convex at length umbilicate, the margin 

 sometimes slightly wavy membranaceous, finely silky white or gray- 

 ish, acquiring at length a pale ruddy tinge. Gills broad, ventricose, 

 adnate, with frequently a more or less distinct tooth, in consequence 

 of which they are sometimes at length decurrent, rose-coloured, as 

 far as I could observe not clothed with any spiculse. Sporidia rose- 

 coloured, elliptic. Stem l|-2 lines high, thickest above, white or 

 grayish like the pileus, quite solid, minutely silky. Smell like that 

 of new flour. 



This species belongs clearly to the subgenus Eccilia of the second 

 series Hyporhodius, and is quite distinct from all described by Fries.

* 4. Ag. glaucopus, Schseff. Fr. Syst. Myc. vol. i. p. 224 — The 

 plate of Sowerby referred to by Persoon and Fries for this species, 

 belongs rather to Ag. callochrous, a, and in consequence the descrip- 

 tion given in the English Flora, which was made with an especial 

 view to it. The true plant, which occurred at King's Cliffe, at the 

 end of October 1835, is one of the finest of our Agarics. 



*5. Ag. speciosus, Fr. Obs. 2. p. 1 — Since the account of this 

 species was given in the Addenda to the English Flora, I have seen 

 Letellier's Supplement to Bulliard, which contains at t. 623. a, 

 (under Ag. volvaceus,) and t. 645, figures of Ag. gloiocephalus, D. C. 

 His figure accords precisely with the plant I have in view, except 

 that there is no indication in it of villosity on the stem and volva, 

 but, as it appears to me, there are no characters to distinguish it 

 from Ag. speciosus. Thevolva is by no means obliterated, the stem 

 not equal, but always more or less attenuated upwards, and some- 

 times even bulbous, and one of the specimens is almost four inches 

 broad. The peculiar manner in which the volva passes under the 

 stem is also the same. 



6. Polyporus ductus, n. s. —On a very rotten plank from an old 

 house, King's Cliffe.
