1 1 J (l rocybe prsepaUens. 



Pileua fleshy, thin, Bubconical, then convex or expanded, glabrous, 

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

 ochraceous when dry. flesh yellowish-white ; lamellae close, lanceolate, 

 rounded behind or slightly emarginate, reddish-umber, becoming 

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

 Blightly silky, pallid or brownish : spores Bubelliptical, .0003 to 

 l in. long, .00025 in. broad. 



Plant 1 to «) in. high, pilous 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 isabeiline hue of the other is very noticeable 

 and BUggestive 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 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 Firmiores. 



Hygrophorus miimtiilus. 



Pileus thin, submembranous, convex or expanded, subumbilicate, 

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

 yellowish when dry ; lamellae rather broad, subdistant, sometimes 

 rentricose, adnate or subsinuate and Blightly 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 h' to 1<> lines high, pileus '>) to 5 lines broad, stem scarcely 

 half a line thick. 



<r iss ground in pastu 3. Sandlake. July. 



This is one of our smallest species of Hygrophorus. Its nearest 



relative is II. <mr<in'' 3 B. & C, from which the viscid pileus 



and stem and less decurrent lamellae separate it. As the moisture 

 from the fresh plant the pileus becomes paler and assum< 



slight silky appearance, but often the thoroughly dried specimens
