PRELIMINARY NOTES ON SOME NEW SPECIES 
OF FUNGI. 
GEO. F. ATKINSON. 
Agaricus cretacellus, Atkinson n. sp. — Plants gregarius, 
sometimes a few jointed at the base; 5-8 cm. high, pileus 4-7 cm. 
broad, stems 6-10 mm. in thickness. Pileus white convex to ex¬ 
panded, thin, smooth, sometimes inclined to be slightly viscid 
in wet weather, when leaves cling to the surface; sometimes with 
slight yellowish stains, flesh white with a tinge of pink sometimes. 
Gills narrow, 3-4 mm., narrowed behind, free, first white, then 
pink, and later dark greyish brown, not becoming blackish. The 
caps are sometimes fully expanded when the gills how only a 
flight tinge of funk. ^Spores 4-5 x 3^. Stem tapering from the 
'enlarged' base, White, smooth above the annulus, chalky white be¬ 
low and covered with minute white powdery scales often ar¬ 
ranged in irregular concentric rings below; stem solid but the 
center less dense. Annulus persistent, white, smooth above, 
the lower surface with very fine floccose scales similar to those 
on the stem from which the annulus was separated. Odor and 
taste of almonds, as in A. arvensis. Growing in leaf mold, 
woods, Cascadilla creek, Ithaca, N. Y. C. U. herb. No. 5359, 
collected by Geo. F. Atkinson, September 7, 1900. 
Amanita flavoconia, Atkinson n. sp.—Plants usually scat¬ 
tered, sometimes gregarious, 6-12 cm. high, pileus 3-8 cm. broad 
stems 4-15 mm. thick. Pileus convex then expanded, plane or 
broadly umbonate, fleshy, very thin except at the center, chrome 
yellow to orange yellow, darker when young and on the center, 
smooth, that is not striate, viscid, flesh white, covered with nu¬ 
merous small fiocculent patches or heaps of fragments of the yel¬ 
low powdery volva, which is easily removed and in wet weather 
sometimes is entirely absent from the pileus. Gills broad in the 
larger specimens, narrow in the smaller ones, 4-8 mm. broad, 
rounded at each end, free, not very crowded, white, very finely 
serrate or fimbriate from threads which attached the gills to the 
stem in the young plants. Spores oval-ovate, white, 6 - 9 X 4 - 6 //. 
Stems stuffed, straight or flexuous, slightly tapering from the 
bulbous base, and at the apex broadening slightly, covered with 
fiocculent scales, tinged with sulphur, fine sulphur powder above 
the annulus, portions below the annulus covered with powdery 
masses or particles of the universal veil. Bulb not very promi¬ 
nent, smooth or rarely somewhat cracked, powdered with rem¬ 
nants of the volva. Annulus sulphur yellow or chrome yellow, 
membranous. The volva or universal veil consists of a yellowish 
powdery substance which separates into numerous powdery 
masses, covering the pileus and base of the stem, but which easily 
falls away.
