NEW SPECIES OF FUNGI. 9 
Hydrocybe przpallens. 
Pileus fleshy, thin, subconical, then convex or expanded, glabrous, 
hygrophanous, watery-brown or chestnut-colored when moist, pale- 
ochraceous when dry, flesh yellowish-white ; lamellz close, lanceolate, 
rounded behind or slightly emarginate, reddish-umber, becoming 
tawny-cinnamon ; stem short, equal, subflexuous,  fleshy-fibrous, 
slightly silky, pallid or brownish; spores subelliptical, .0003 to 
.0004 in. long, .00025 in. broad. 
Plant 1 to 3 in. high, pileus 6 to 18 lines broad, stem 2 to 4 lines 
thick. 
Naked soil in woods. Sandlake. June. 
The difference in the color of the moist pileus and the dry one is 
quite decided. The change from the dark-chestnut color of the one 
to the dingy-yellow or isabelline hue of the other is very noticeable 
and suggestive of the specific name. The fibrils of the veil are 
grayish-white, and the margin, which is at first incurved, is apt to 
become wavy, irregular or reflexed in large specimens. In the 
thinner specimens it is striatulate when moist. The lamelle are nar- 
rowed toward the outer extremity and when young are of a peculiar 
reddish-brown or dark-ferruginous hue. The stem is usually hollow, 
but apparently from the erosion of insects. The species belongs to 
the section FrRMIORES. 
Hygrophorus minutulus. 
Pileus thin, submembranous, convex or expanded, subumbilicate, 
bright-red, viscid and distantly striatulate when moist, pale-red or 
yellowish when dry; lamelle rather broad, subdistant, sometimes 
ventricose, adnate or subsinuate and slightly decurrent, whitish, 
tinged with red or yellow; stem short, slender, fragile, solid, viscid 
when moist, yellowish ; spores narrowly elliptical, .0004 in. long, 
.0002 in. broad, borne on slender spicules which are .0002 to .0003 
in. long. ; 
Plant 6 to 10 lines high, pileus 3 to 5 lines broad, stem scarcely 
half a line thick. 
Grassy ground in pastures. Sandlake. July. 
This is one of our smallest species of Hygrophorus. Its nearest 
relative is HZ. aurantiacoluteus B. & C., from which the viscid pileus 
and stem and less decurrent lamellae separate it. As the moisture 
escapes from the fresh plant the pileus hecomes paler and assumes a 
slight silky appearance, but often the thoroughly dried specimens
