delecta, Karst., Hattsv., i, p. 460; Sacc., Syll. v, p. 783 ; Ag. ( Ino .) caesariatus 
var. fibrillosus, Fries, Icon. Sel., tab. 109, f. 3. 
P. convex then plane, scarcely depressed or umbonate, fibrillosely scaly, dingy, 
tawny- or rufous-honey-colour, pale rufous-cinnamon when dry, about 5 cm. ; g. 
emarginate, crowded, ventricose, pale honey-colour then with an olive tinge, finally 
brownish, edge paler and crenulate; s. solid, equal, slightly curved, dingy yellow or 
rather pallid, white fibrillose, apex nearly naked, 3-5 cm. Flesh yellowish then 
white. 
Near paths in pine woods. Sweden, Finland. 
viscosissima, Karst., Hattsv., p. 465 ; Sacc., Syll. v, p. 789; Agaricus viscosis- 
simus , Fries, Icon. Sel., ii, p. 9, tab. no, f. 2. 
P. persistently convex, acutely umbonate, brownish umber, very glutinous then 
silky, 2-2*5 cm. ; g. rounded behind and almost free, ventricose, rufescent ; s. sub- 
fistulose, equal, glabrous, pallid, not fibrillose but usually white-pruinose, 3-4 cm. 
On the ground in pine woods. Sweden. 
Allied to I. trechispora , but differs in the colour of the pileus, and the glutinous 
coating, which is present in sufficient quantity to drip to the ground. Qu^let (Flor. 
Myc. 102) gives the present species as a synonym under his I. umbonata. This 
however cannot be correct, as the last-named Fungus has the stem floccose up to 
a distinct ring, and is obviously a Stropharia. 
Excluded Species. 
umbonata, Qu£l., Bull. Soc. Bot. Fr., 1876, p. 330, pi. 2, f. 4. 
This is undoubtedly a species of Stropharia with the stem floccosely peronate up 
to the ring. It was originally called Agaricus ( Stropharia ) inunctus, Fr., by Qu^let 
(Champ. Jur. et Vosg., i, p. no). 
psamminum, Sacc., Syll. xi, p. 50 (foot-note) ; Ag. (Heb.) psamminus , Berk. 
This species is a Flammula , and will stand as F. psammina. 
plumosa, Karst., Hattsv., p. 455 ; Sacc., Syll. v, p. 763 ; Ag. {Ino) plumosus , 
Fries, Mon., i, p. 337; Ag. plumosus, Bolton, Hist. Fung., i, p. 33, pi. 33 (1788). 
On carefully going over Bolton’s description of his Fungus, I can find no justifica- 
tion for its retention in the genus Inocybe. He distinctly states that the gills are 
white , both in his Latin diagnosis, and in his general description of the species. On 
this point Bolton can be trusted, judging from his usual accuracy in colour descriptions. 
It was Fries who first suggested that Bolton’s plant belonged to the section 
Inocybe , and described the gills as ‘ albido-fuligineis,’ and most people have accepted 
the description given by Fries of what he supposed to be Bolton’s Fungus. 
No one in Britain has found an Inocybe corresponding to Bolton’s figure and 
description since Bolton’s time. I am inclined to think that the Fungus Bolton had in 
view was a species of Collybia of the section Vestipedes. 
The following is Bolton’s description of the Fungus under consideration : — 
‘ Agaricus stipitatus, pileo hemispherico plumoso murino, lamellis trifidis albidis 
stipite longo plumoso.’ 
‘ The root is round, hard, the size of a pea, of a brownish-black colour, and 
emitting a few long hard fibres ; it is not surrounded by a volva.
