tat, consistency, pubescence, color, etc. It is known in Ohio 
only from a collection made at Cincinnati (now in the Lloyd 
Museum) by Mr. Wm. Holden. For illustrations see Lloyd,

55. P. circinatus Fries, Monogr. Hymen. Suec. 2:268. 1863. 
Pileus stipitate or substipitate, circular to spathulate or 
flabelliform, convex to depressed, 3-9 em. broad, 0.3-1 cm. 
thick, rather soft when fresh, firm when dry, yellowish to 
umber-brown, tomentose to velvety, azonate ог subzonate, 
margin rather thin, acute; context yellowish to cinnamon- 
brown, duplex, soft and spongy above, firm next to the tubes, 
1-6 mm. thick; tubes 1.5-4 mm. long, the mouths whitish to 
cinnamon, subcircular to angular, averaging 2-4 to а mm.; 
stipe sometimes rudimentary, usually lateral or excentric, 
fulvous to dark brown, tomentose, soft, up to 5 cm. long, 
0.5-1.5 em. thick; spores (teste Lloyd) pale color, 3 x 5 в. 
In coniferous and deciduous woods. 
The species has not been reported from Ohio. It is distin- 
guished by the duplex character of the context and by the poor 
development of a stipe. It is a question whether it is distinct 
from P. tomentosus Fr. Certainly P. dualis Peck is the same 
plant. Lloyd regards American plants in which the context 
is always duplex as belonging under P. circinatus Fries, and 
European plants with a uniform context as P. tomentosus Fries. 
The plant is illustrated by Lloyd (Myc. Notes Polyp. Issue 
f. 198-99).

Stipitate. Stipe central, spongy, velutinous, dark cinnamon, 
4-6 em. high, 0.5-1.5 em. thick above, enlarged below to 1-3 
em.; pileus convex then depressed in the center, obconical 
at first with the margin obtuse, then spreading out with the 
margin acute, color lighter than that of the stipe, yellowish 
cinnamon, surface uneven, subcolliculose, not zonate, 4-6 cm. 
across; pores irregular, short (1 mm.), at first round with margins 
thick, finally irregular and subsinuous, 0.5-1 mm. across, 
margins acute; spores elliptical, ferruginous, 7-8 x 4-5 р.
