pileus. The mature lamellae appear velvety when viewed by the 
aid of a lens. This is due to the abundance of the prominent spores 
that cover their surfaces. 
Hygrophorus immutabilis n. ap. 
Pileus thin, conical or convex and umbonate, often striate when 
dry, greenish brown or yellowish brown, not changing color in 
■drying; lamellae subdistant, whitish or yellowish; stem slender, 
glabrous, hollow, yellow; spores elliptic, .0004 to .0005 in. long, 
.00024 to .00028 broad. J 
Pileus 8 to 12 lines broad; stem 1 to 2 in. long, 1.5 to 2 lines 
thick. 
Dryish sandy or heathy places. Raybrook, Essex county. 
August. 
This plant is manifestly closely allied to Hygrophorus conicus, and 
might easily be considered a mere variety of it. It differs, however, 
in being less regularly and acutely conical, in having no orange, 
scarlet or red hues, in its paler or whitish lamellae and specially in 
its unchangeable color. Specimens of H. conicus collected at the 
same time and place and subjected to the same method of drying 
turned black, as usual, but these retained their colors. 
Clavaria fellea n. sp . 
Clubs about 1 inch high, ochraceous yellow, sparsely and sub- 
dichotomously branched; stem terete, solid; branches crowded, 
nearly parallel, the tips obtuse, concolorous; spores globose, .00024 
in. broad; mycelium white. 
Under oak trees. Gansevoort. July. Related to C. muscoides. 
The flavor is bitter and slightly farinaceous. 
Boletus nebulosus n. s 79. 
Pileus convex, dry, snuff brown or smoky brown, flesh white, 
unchangeable; tubes convex, depressed around the stem, pallid or 
brownish, becoming purplish brown where wounded, the mouths 
small, rotund; stem enlarged toward the base, solid, scurfy, colored 
like the pileus; spores .0005 to .0006 in. long, .00024 broad.
