5. P. Scliwemitzii, F r . ; pileus thick, spongy, then corky,
strigoso-tomcntose, rough, bright-brown; stem thick, very
short or obsolete, ferruginous; pores large, often torn and
irregular, sulphur-green.—Sv. Bot. t. 720.
Amongst the roots of pines. Very rare. Dorsetshire,
C. E. B. The first specimens found, M'hich exactly agree
with P. Schweinitzii, var. dimidiatus, were referred, because
of the total absence of a stem, to P. Herbergii, Rostk.
6. P. rufesoens, F r .; flesh-coloured; pileus spongy, then
corky, soft, unequal, hairy; stem short, irregular; pores large,
sinuated and torn, white, tinged with flesh-colour.—Sow. 190.
On tlie ground, about stumps. Not uncommon. Sometimes
very beautiful. Stem often lateral, and in densely imbricated
specimens sometimes obsolete.
7. P. perennis, F r .; cinnamon, then bright-brown; pileus
coriaceous, then plano-infundibuliform, velvety, at length
smooth, zoned; stem firm, thickened below, velvety; pores
minute, angular, acute, at first veiled with a white substance,
then naked and torn.—Sow. t. 192; Huss. i. t. 51.
On the ground and on stumps, mostly iu subalpine countries.
Not uncommon.
2. Stem lateral.
8. P. squamosus, Fr.; pileus fleshy, but tough, flahelliform,
expanded, pallid, variegated with broad, adpressed, spot-like,
centrifugal scales; stem excentric and lateral, blunt, reticulated
above, black at the base; pores thin, irregular, at length
broad, angular, and torn, pallid.—Grev. t. 207. Huss. i. t. 33.
On trunks of trees, especially Ash. Extremely common.
9. P. Eostkovii, F r . ; pileus fleshy, but tough, dimidiate,
somewhat infundibuliform, smooth, even, dingy; stem long,
excentric, reticulated, abruptly black, thickened at the base;
pores decurrent, broad, pentagonal, acute, toothed, white, then
dirty-yellowish.—Rostk. t. 17.
On old stumps. Rare. Apethorpe, Northamptonshire.
Much thinner than the last.
10. P. pieipes, F r . ; pileus fleshy, but coriaceous, rigid,
tough, even, smooth, depressed behind and in the centre; stem
excentric and lateral, equal, firm, at first velvety, then naked,
dotted black up to the round, small, tender, white, then red-
dish-grey tubes.—Grev. t. 202.
On trunks of trees. Not uncommon. Pileus ochraceous
or rufous.
11. P. varins, F r . ; pileus fleshy, but tough, thin, soon
woody, smooth, somewhat virgate, irregular, depressed behind
or in the centre; stem excentric and lateral, even, smooth,
becoming gradually cinereous downwards; pores dccurrent,
minute, short, round, unequal, whitish, then watery-cinnamon.—
Bolt. t. 168.
On trunks of trees. Not uncommon.
12. P. elegans, F r . ; pileus equally fleshy, soon hard and
woody, flattened out, even, smooth, self-coloured; stem excentric
or lateral, even, smooth, pallid, from the first abruptly
black at the base, rooting; pores plane, minute, nearly round,
whitish-yellow, becoming pallid.—Bolt. t. 83.
On trunks of trees. Not uncommon. The limits of these
three species are, however, very difficult to seize. P. num-
mularius, whose pileus scarcely exceeds an inch in diameter,
and is occasionally almost velvety when young, though quite
smooth when old, has, perhaps, quite as great pretensions to
be separated as a species.
13. P. quercinus, F r . ; pileus soft, corky, tongue-shaped,
very thick, convexo-plane, even, at first flocculoso-granulated,
tan-coloured, becoming pallid, narrowed behind into a thick.
