and easily separable.—Fr. S. M. p.

Gregarious, often anastomosing, or two or three growing into each other
scentless, brittle, whitish, at length yellowish, or tinged with brown ; stem’
attenuated below, central or lateral, about an inch high ; pileus about 1 in.

Teeth formed at an early stage of

or like network, and connected to gether.

Hymenium inferior, at first toothed,
te e th variable, firm, somewhat coriaceous,
acute, entirely concrete with the pileus
p la c e /n rows, or netted and connected at thé
base into lamellæ, or porous folds. Ligua-
tile fungi, rather coriaceous, approaching
Lenzites and Dædalea, but the hymenium is
toothed from the first, the teeth not lacerated.—

Pilei 1 in. or more broad, very thin, somewhat resembling paper, capable
of being folded up or stretclied, concrete or infuudibuliform, from a stem-
like base, clothed with long, even, pilose scales, so closely pressed that the
whole surface appears slightly rugulose; spines distinct, chiefly seated on
the produced base, which is at length brownish, various in form, generally
disposed in rows.—Fries.

Pure wbite, coriaceo-membranaceous, separable from the

Cn dead branches of beecb.
Two inches long, effused, with the margin reflexed all round, and the
teeth exactly resembling those of many true species of Hydnum, but on
minute inspection they will be found to be seated upon flue folds, and dis-
posed in rows.—M .J B.

“ This spreads in irregular patches on the surface of decaying wood. The
pores for a small space round the margin are round and distinot, but towards
the centre greatly lengthened out, lying one upon another in an imbricated
manner. The colour is white at first, when old it changes to a
yellow brown, and at last to a dirty, fuscous hlaek.”—Bolton. (Fig. 73.)
