NEW SPECIES OF FUNGI. \) 



Hydrocybe prsepallens. 



Pileus fleshy, thin, subcortical, then eonvex or expanded, glabrous, 

 hygrophanous, watery-brown or chestnut-colored when moist, pale- 

 ochraceons when dry, flesh yellowish-white ; lamella? close, lanceolate, 

 rounded behind or slightly emarginate, reddish-umber, becoming 

 tawny-cinnamon ; stem short, equal, snbflexuous, fleshy-fibrous, 

 slightly silky, pallid or brownish ; spores snbelliptical, .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 lamellae are nar- 

 rowed toward the outer extremit}^ 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 Firmiores. 



Hygrophorus minutulus. 



Pileus thin, submembranous, convex or expanded, subumbilicate, 

 bright-red, viscid and distantly striatulate when moist, pale-red or 

 yellowish when dry ; lamella? 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 H. aurantiacoluteus B. & C, from which the viscid pileus 

 and stem and less decurrent lamella? separate it. As the moisture 

 escapes from the fresh plant the pileus becomes paler and assumes a 

 slight silky appearance, but often the thoroughly dried specimens
