122 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
On the ground, in contact with and partly attached to decay- 
ing pine limbs partly buried in the soil. (Тһе above description 
is according to Ellis and Everhardt, Bull. Torr. Bot. Club. 24: 
125. 1897.) 
Distinguished from the next three species by the greater 
thickness of the pileus and stipe. From P. circinatus Fries, 
it is separated by the absence of a duplex context and by the 
slightly smaller pores. The plant is recorded by Morgan as 
P. Montagne Fries, but according to Lloyd the record is based 
on plants collected in Canada by Dearness. It is listed in Lea’s 
catalogue under the same name. 
57. P. focicola Berk. & Curt. Jour. Linn. Soc. Bot. ro: 
305. 1808. 
Pileus stipitate, circular in outline, convex-depressed to 
umbilieate, 2-4 cm. broad, 1-6 mm. thick, coriaceous when 
fresh, rigid when dry, grayish brown to cinnamon, finely tomen- 
tose, striate, zonate, margin thin and acute; context cinnamon- 
brown, fibrous, less than 0.5 mm. thick; tubes 1-6 mm. long, 
the mouths angular or irregular, cinnamon to rusty brown, 
averaging 1 mm. or more in diameter; stipe central, light to 
dark brown, minutely velvety, 1.5-3 em. long, 2-4 mm. thick 4 
spores (teste Lloyd) pale colored, smooth, elliptical, 5 x 10 y. 
On burned earth in woods. July to November. Rare. 
The species differs from P. perennis L. ex Fries only in the 
much larger pores. Тһе plants were reported by Lea as P. 
connatus Schw. and by Morgan as P. parvulus Klotzsch. Тһе 
plant is well illustrated by Lloyd (Myc. Notes Polyp. Issue 1: 
f. 208-4).

Pileus stipitate, cireular in outline, convex-depressed to 
umbilieate, 1.5-7 cm. broad, 1-3 mm. thick, coriaceous, rigid 
when dry, grayish brown to cinnamon or rust-colored but never 
silky, finely tomentose, zonate, margin thin and acute ; context 
cinnamon-brown, fibrous, less than 1 mm. thick; tubes 1-2.5 
mm. long, the mouths grayish to cinnamon, angular, averaging 
2-4 to a mm.; stipe central or subcentral, cylindrical, con- 
colorous with the pileus, velvety, 1.5-5 cm. long, 1-6 mm. 
thick; spores (teste Lloyd) pale colored, 4-5 x 8-10 ,.
