then glabrous, produced behind, sessile or resupinate, sordid luteous. 
Lamellz decurrent, close, branched, crisped, luteous. Spores sordid, 
somewhat oblong, .0050.0035 mm. ; 
Growing on a rotten log in a piece of woods near Fairmount, Cincin- 
nati; the specimens grew in the same place from early spring till late 
in autumn. Pileus 1-2 in, broad and about the same length, more or 
less lobed about the margin. Although not fitting the description 
perfectly, yet it comes so near that there does not seem enough 
difference to make a new species. 
Genus VI.—Hyeropnorvs, Fr. 
Hymenophore contiguous with the stipe, and descending unchanged 
into the trama. lLamelle with the edge acute; the hymenium chang- 
ing into a waxy mass. Spores white. Fungi terrestrial.

1. H. Laur#, n. sp.—Pileus fleshy, convex and umbonate, then 
expanded and depressed, more or less irregular, glutinous, white 
clouded with a reddish or brownish tinge especially on the disk. 
Stipe solid, more or less curved or crooked, tapering downward, yellow- 
ish-white; the apex scabrous with scaly points. Lamelle unequally

0083 .0055 mm. (See Plate IX.) 
Growing in rich soil among the leaves in hilly woods. Pileus 2-4 in. 
broad, stipe 2-4 in. long and $ an inch thick. This is a much laiger 
plant than H. eburneus, has a wash of red or brown upon the disk, and 
is covered with a thick gluten. It is more like H. cossus, but has no 
odor. 
2. H. EBuRNEUS, Bull.—Pure white. Pileus fleshy, convex then 
plane, even, viscid, the margin soon naked. Stipe stuffed then hollow, 
unequal, viscid, scabrous at the upex with scaly points. Lamelle de- 
current, distant, straight, firm. Spores .0056x.0043 mm. 
In woods, common. Pileus 2-3 in. broad, shining when dry; stipe 
at length hollow, various in stature, flexuous in elongated specimens.
