16. SCHIZOPHYLLUM, Fr.
Gills coriaceous, split longitudinally, with the two divisions
rcvolute, or spreading.
1. S. commune, Fr.; pileus adnate behind, simple, and
lobed; gills grey, then brownish-purple, the divided surface
villous, the edge revolute.—Sow. t. 183.
On dead wood, mostly such as has been imported. I have
seen this beautiful plant in profusion on foreign wood, hut I
have never gathered truly British specimens, which are extremely
rare.
17. LENZITES, Fr.
Corky or coriaceous. Gills firm, often anastomosing, and
forming spurious pores. Edge entire.
1. L. betulina, F r .; pileus between corky and coriaceous,
firm, somewhat zoned, tomentose, turning pale; margin of
the same colour; gills straight, somewhat branched, anastomosing,
pallid. (Plate 15, fig. 3.)
On stumps, old rails, etc. Very common. Varying greatly
in colour, in the degree of hardness, and in the anastomosing
of the gills. Often quite resupinate, and then very deceptive.
2. L. ftaeeida, Fr.; pileus thin, coriaceous, flaccid, unequal,
zoned, hairy, turning pale ; margin of the same colour; gills
broad, crowded, unequal, and branched, white, then pallid.—
Bull. t. 394; Bolt. t. 158.
On stumps. Not uncommon. Bunning by almost imperceptible
gradations into the last.
3. L. sepiaria, F r .; pileus hard, coriaceous, zoned, stri-
goso-tomentose, rough, bright brown; margin and the thick-
ish branched anastomosing gills tawny.—Sow. t. 418.
On fir-wood, mostly imported. Occurring sometimes in
great quantities on fir-poles, on railway platforms, etc.
4. L. abietina, F r .; pileus thin, coriaceous, effuso-reflexed,
nmher, clothed with umber-coloured down, at length smooth
and whitish; gills simple, decurrent, unequal, brownish, with
a glaucous bloom.—Bull. t. 442. / . 3.
On deals. Glasgow, Klotzsch. Very distinct from the
last. Not at all tawny.
Order 2. POLYPOBKI.
Hymenium lining the cavity of tubes or pores, which arq
sometimes broken up into teeth or concentric plates.
18. BOLETUS, Fr.
Hymenophorum quite distinct from the hymenium. Trama
obsolete. Hymenium lining the cavity of tubes separable
from one another and from the hymenophorum,
1. Spores ochraceous.
* Pileus covered with a viscid pellicle ; stem solid, neither
reticulated nor hulhous.
1. B. luteus, L. ; pileus gibbous, then pulvinate, smeared
with a brown evanescent gluten; stem dirty-yellow, equal,
firm, dirty-white, rough with dots ahove the hroad, memhranaceous,
whitish-hrown ring ; tubes adnate, minqte, simple,
yellow.—Schceff. t. 114; Kromb. t. 33.
In fir-woods. Fries says that this has been found once
only in Great Britain, but it is our commonest species.
3. B. elegans, Schum.; pileus convexo-plane, viscid, golden-
