zoned, edge white, generally very irregular, attached to sticks, dirt, etc; 
when young slightly silky, later smooth, shining. With age the pores 
are filled up and become dark and sterile in patches, covered here and 
there by a new white hymenium; smell-like that of Boletus edulis\ text¬ 
ure of soft leather; pores at first .2 to .3 mm. broad. 
T. mollis (Sommerf.) Fr. Resupinate, submembranaceous, pallid 
wood-color, then fuscous, margin at length revolute, dark and pubescent 
underneath; pores ample, unequal and torn. On maple, birch, etc. 
T. screens Fr. Dry, closely adnate-resupinate, erumpent, tuberculi- 
form, orbicular, then confluent, white, border determinate, pubescent; 
pores roundish or angular, unequal, obtuse. At length paler. 
T. sepium Berk. Effused at base, reflexed, often laterally confluent, 
finely tomentose, repeatedly zoned, pale wood-colored, coriaceous ; sub¬ 
stance white; hymenium pallid; pores slightly sinuated, about in. 
across. Widely distributed. 
T. serialis Fr. Towy-corky, effuso-reflexed, seriately extended, narrow, 
confluent, wrinkled and pitted with soft appressed hairs, white at first, 
then brown or brownish red; margin obtuse; pores obtuse, minute, un¬ 
equal, white. Commonly resupinate. On spruce. 
T. versa tills Berk. Long effused, margin broadly reflexed, whitish, 
extremely thin, flexible, clothed with coarse down, silky towards the 
margin, which is acute and pale bay; pores nearly of the color of the 
margin, deep, regular at first, then variously sinuated; dissepiments 
toothed, elongated, longest towards the base. Louisiana. 
Distinctly pileate, but in some cases effused at base (C, D, and E). 
C. Pileus covered with hairs. 
T. hydnoides (Swartz) Fr. Flat, zoneless, dark bay or brown, covered 
with rigid branching dark hairs; within ferruginous; pores minute, 
rounded, equal, obtuse, ferruginous. Very common in warm regions. 
Often becoming nearly bald with age; variable in color, size, and 
thickness. 
T. Feathermamii Rav. is said to be a form of the last, very dark, cori¬ 
aceous, with thick hairs. 
T. Trogii Berk. Fuscous, subolivaceous; pileus convex, at first 
smoothish, unequal, then covered with rigid hairs 3 lines long, and 
somewhat zonate, margin acute, substance white ; pores somewhat angu¬ 
lar, toothed. Dead poplar. Eur. 
T. Pechii Kalchbr. Sub-decurrent, brownish ferruginous, becoming 
pale, hairy, zoneless, margin acute; substance wood-color, pores rather 
large, rounded angular, nearly concolorous, or becoming brown. Hairs 
longer, pores larger and darker than in the American form of T. Trogii. 
Distinguished by the seal brown hairs. West. Said to be T. funalis 
(Fr.) Ell. & Ev. ' 
T. Lindheimeri B. & C. A southern species, pale tawny, plane, covered 
with soft matted strigose hairs, with thin margin and pores at length 
dingy umber, of medium size, slightly angular, dissepiments thin, often 
elongated into teeth, is now referred to Polystictus (Cooke). 
D. Pileus or substance brown, brownish , or tawny. 
T. trabea (Pers) Bres. = T. protracta Fr. = Daedalea pallido-fulva 
Berk. = Lenzites vialis Peck. A very widely distributed species, so vari¬ 
able that forms have been referred to three genera. Pileus brown, some¬ 
times rather pallid, usually reddish or tawny, rough or uneven, somewhat 
pubescent, sometimes zoned; usually rather narrow and often much 
extended laterally. Hymenium pallid, or somewhat flesh-color or cine¬ 
reous, or brownish like the substance of the pileus. T. protracta has 
pores of medium size, round, rather distant, hymenium tawny, according 
to Fries. For the other forms see under D. pallido-fulva and L. vialis.
