em. thick, fleshy or fleshy-tough when fresh, more or less friable 
when dry, yellowish brown or darker, finely tomentose or fibril- 
lose-scaly, often becoming glabrous, azonate; margin thin and 
acute, often involute on drying; context white or light yellow- 
ish, soft and spongy, 2-6 mm. thick; tubes 1-5 mm. long, 
decurrent on the stipe, the mouths white or brownish on drying, 
circular to angular and irregular, averaging 2-3 to а mm.; stipe 
central, simple or rarely branching once or twice, yellowish or 
brownish, prolonged below into a long, black, rooting base, 
velvety or rough-squamulose above, 6-15 cm. long, 0.5 to 2 cm. 
thick; spores white, smooth, ovoid-elliptical, 6-8 x 12-15 y. 
Growing on the ground, sometimes around stumps, and prob- 
ably attached to buried wood. Common. 
This plant is always easily recognized by the black and radi- 
cating base of the stem. The type specimens of P. Morgani 
Peck were collected іп Ohio by Morgan. For illustrations see 
Hard, Mushrooms f. 329., Lloyd, Syn. Sec. Ovinus f. 508; 
Syn. Stip. Polyp. f. 465., and Ohio Myc. Bull. 11: f. 46.

Pileus stipitate, circular to irregular in outline, 4-10 cm. 
broad, 0.3-0.8 ст. thick, soft and fleshy when fresh, rigid but 
friable when dry, yellowish green or yellowish brown in color, 
the surface often cracked and areolate and the flesh showing 
yellowish in the cracks, slightly tomentose or glabrous, azonate, 
the margin thin and acute; context white or yellow, fleshy when 
fresh, soft and friable when dry, 1-4 mm. thick; tubes 1-5 mm. 
long, decurrent on the stipe, the mouths white or yellowish, 
sometimes reddish on drying, circular to angular, averaging 1-3 
to а mm.; stipe simple or branched, usually excentrie but some- 
times central, often irregular in form, whitish or yellowish in

globose, ог subglobose, 3—4.7 шіп diameter. 
Growing on the ground in deciduous woods. Frequent in 
July and August. 
А species easily recognized by the color of the pileus. Тһе 
plant is fairly well represented by Hard (Mushrooms f. 327), 
and by Lloyd (Syn. Sect. Ovinus f. 501). According to Lloyd 
P. cristatus Pers. of Europe is not different from our plant, 
Murrill lists it under the name of Grifola poripes Fries ex Murr,
