Lentinus cochleatus Fr. 
SHELL LENTINUS 
Pileus thin, tough, flaccid, irregular, often lobed on the margin, 
plane, centrally depressed or infundibuliform, glabrous, rufescent 
or brownish flesh color when moist, paler when dry; lamellae rather 
broad, close, decurrent, serrate on the edge, whitish tinged with 
flesh color; stem central, eccentric or lateral, usually crowded and 
united in a tuft, solid, glabrous, sulcate, colored like or paler than 
the pileus; spores minute, subglobose, .ocoo16—.0002 of an inch in 
diameter. 
Pileus .5~2 inches broad; stem 1.5—3 inches long, 2-4 lines thick. 
On and about old stumps or growing from decaying wood 
buried in the ground. Adirondack region. July and August.

and its grooved stem. The plants sometimes emit an agreeable

N. Y. State Mus. Rept 28, p.51, pl.1, fig.15-190 
Pileus fleshy but thin, tough, glabrous, deeply umbilicate, hy- 
grophanous, brownish tan color when moist, paler when dry; 
lamellae close, adnate or decurrent, serrate on the edge, whitish; 
stem short, slender, glabrous, nearly even, tough, stuffed or hollow, 
central or eccentric, coiored like the pileus. 
Pileus 6-12 lines broad; stem 8-12 lines long, I-1.5 lines thick. 
Ground and decaying ariod: Gregarious. Hamilton and Essex 
counties. July and August. 
This small species resembles Lentinus cochleatus Fr. 
in texture and color, but it is a much smaller plant, gregarious in 
its mode of growth and without furrows on the stem. It is 
closely related to Lentinus omphalodes Fr. from which 
it has been separated on account of its hollow stem without elon- 
gated furrows or lacunae and its darker color. 
Lentinus ursinus Fr. 
BEAR LENTINUS 
Pileus fleshy, tough, sessile, dimidiate, often imbricated, even 
or sometimes costate corrugate on the margin, at first whitish and 
glabrous then reddish brown and hairy or tomentose toward the
