will at once show. 7” elegans has occurred in this country on 
fowl’s dung. 
1497. Agaricus (Collybia) Stevensoni, B. & Br.  Pileo 
semiovato, obtuso, viscido, pallide luteo hic illic e visco macu- 
lato; stipite tenui fibrilloso sursum pulverulento extus intus- 
que rufulo radicato; lamellis latis adnatis, dente decurrentibus 
distantibus candidis. 
Glamis, Rev. J. Stevenson, Aug. Pileus 4 inch across and 
high; stem 14 inch high, scarce a line thick, composed of 
fibres. 
Allied to Ag. ventricosus, but differing in its slender almost 
solid stem, viscid semiovate pileus, and very broad, adnate, 
somewhat ventricose plane gills. 
1498. Agaricus (Hypholoma) sz/aceus, P. 
Glamis, Rev. J. Stevenson.. 
Pileus viscid, bright orange rufous; stem 4 inches high, 
at length hollow, solid and shghtly swollen at the base. 
Smell resembling that of meal. Spores pale purple-brown. 
1499. Cortinarius (Inoloma) traganus, Fr., var. finitimus, 
Weinm. p. 155. 
Torres, Rev. J. Keith. 
Smell not at all that of the typical form, but pleasant though 
peculiar, resembling that of gum just beginning to ferment. 
Pileus silky, at length smooth, lilac, as is the stem, which is 
yellowish and mottled within, but not saffron-coloured nor 
brown. 
This peculiar form is the more interesting as it has not been 
met with in Sweden. 
1500. Hustegia arundinacea, Fr. Peziza Kneiffit, Wally. 
New Pitsligo, Rev. J. Fergusson. 
(Quite different from a form of Peziza fusca, which is named 
in some herbaria P. Knecffit.
