then corky or coriaceous, regular, irregular, lobed or
dimidiate. Stem short, irregular. Pores irregular, changing
colour. Spoores white. Mostly terrestrial, lasting through
the winter in a dead state, not perennial. 1523, 1524
d. Subcoriaceoe. Pileus at first indurated, arid ; when full grown
corky or coriaceous, tomentose, velvety. Stem definite,

Growing on wood.
a. Lenta. Pileus fleshy-pliant, zoneless. Stem excentric,
blackish at the base. Tubes short. Substance somewhat
fibrous, pallid. 15-27—1534
b. Suberosolignosa. Pileus thick, hard zoneless. Stem stout,

AT • Merismatæ. IVith many branching stems proceeding from a
common trunk, each as a rule bearing a pileus or pileolus
The largest of fungi are found in this group.
a. Carnosa. Tufts central, stipitate, springing from a common,
more or less concrete base. Pileus fleshy firm floccoso-
fibrous, zoneless, not coriaceo-indurate. Tubes separating
from the pileus. Spores white. Partly terrestrial. Autum-
nal. Edible. 1536—1539
b. Lenta. From the tough pileus. Tufts lateral, substipitate
in many imbricate layers. Pileus fleshy-pliant, then sub-
coriaceous, fragile when old, more or less zoned, fibrous
within. Stems more or less connate, or growing from a
common tuberous base. Growing at the base of trunks.
Spores white. Autumnal, not lasting till the following
spring. Not edible. 1540—1542
e. Caseosa. Tufts sessile on the stems of trees, commonly
dimidiate, but in horizontal positions, central and expanded
on all sides. Springing from a tubercular base into
numerous pileoh. Pileus cheesy, at first soft and juicy
* en and, without a pellicle, zoneless. Tubes separating!
Growing in spring and summer, soon decaying. Acid.
1543—1546
d. Suberosa. Tufts somewhat sessile, lateral or central. Pilei
or Pileoli corky or coriaceous, persistent, tough, free at
the base, not effused. Substance floccose, somewhat soft,
suitable for tinder. Tubes adnate. On trunks close to
the ground. Not edible. 1547, 1548
A podæ. Pileus sessile, adnate by a thickened, dilated base,
dimidiate or entire, attached behind, commonly by an
umbo ; more rarely attenuate and sessile. On wood.
Polymorphous. 1549— 1575
a. Anoderniea. Pileus somewhat fleshy, without a cuticle, the
surface broken into flocci or fibres, zoneless, the substance
transversely zoned within and more or less fibrous. Annual,
not reviving.
Pileus cheesy, at first watery-soft, fragile, flocculose, not bristly-
hispid ; when fully grown, soft to hard, but soon putrefying,
not lasting through the winter. Tubes white.
Pores round, entire, obtuse, without small teeth. Not
becoming hard. 1549—1553
Pores elongate, flexuous, acute and torn. 1554—1559
Pileus tough, fleshy-pliant, soft, elastic, villoso-tomentose.
Tubes somewhat adnate, coloured. Lasting till the following
spring.
Substance coloured. 1560—1562
Substance white or slightly brownish. 1563—1568
At first moist, spongy, when dry firm, elastic, usually bristlyhisped,
internally fibrous. Autumnal, annual. The finest
examples growing on living trunks. Must not be confounded
with the section Stupposa of Polystictus, where the
members are dry and rigid.
Substance coloured. 1569, 1570
Substance and spores white. 1571, 1572
b. Placodermea. Pileus clothed with a continuous crust, zoneless
or concentrically sulcate. Persistent.

Mesopodæ.
a. Carnosa.
1517a. P. flavovirens Berk. & Rav. (from the yellowish-green colour
of the pileus ; flavus, light yellow, vireo, to be green) a.
P. soft, pulvinate or depressed, irregularly lobed, subtomentose,
dull yellowish-green, yellowish-olive or olive. St. slightly
attenuate downwards, pallid, paler than P., or shaded white
and yellowish. T. slightly to very decurrent, short, irregular.
