DECADES OF FUNGI. 575 
Has. Penguite, attached to roots of Pleurandra riparia. 
Solitary or slightly cæspitose. 
Pileus fleshy, convex, at length occasionally cracked towards 
the margin, smooth red, five inches across. Stem nearly smooth, 
not reticulate, equal or slightly attenuated below, springing from 
a mass of earth traversed by mycelium, and surrounding the roots 
or base of the stems of Plewrandra riparia. Pores perfectly free, 
leaving a deep pit round the stem, compound irregular pale orange- 
yellow. Spores obovate, pointed below, of nearly the same size 
and shape as in B. chrysenteron. 
Allied to the above-mentioned species, but differing in several 
particulars, and very remarkable from its peculiar habit, in which, 
perhaps, B. su/fureus, Krombholz, alone agrees with it. In the 
larger solitary specimens, the character of the free tubes is not so 
strongly marked. 
197. Polyporus pelliculosus, n. s.; versiformis, demum fibroso- 
suberosus ; pileo badio-fusco strigoso ; margine albo; poris 
inæqualibus parvis, dissepimentis tenuibus lacerato-denticulatis. 
Has. On dead logs and roots of trees. Penguite. May, July. 
Extremely variable in form and size, 1-6 inches across, 
orbicular with the rudiments of a stem, dimidiate or spathulate. 
Pileus, when dry, hard, composed of radiating fibres, some of 
which go towards the pores, others to the surface, which is clothed 
with rough, hispid, fasciculate hairs of a deep brown, with the 
interstices paler, sometimes distinctly zoned; margin obtuse or 
acute, white when fresh ; substance white towards the pores, 
brownish towards the surface. Hymenium white; pores small 35 
of an inch across, irregular, unequal; dissepiments thin; edge 
toothed and lacerated. 
This is evidently very closely allied to P. Weinmannii, Fr., but 
the pileus has no rufous tinge, and it is very hard when dry. The 
pores, as in that species, probably become brown when touched, - 
as such an appearance is indicated in the specimens. The colour 
is nearly that of dry specimens of P. resinosus. I have about 
twenty specimens before me which exhibit great variety of form, 
but agree in their principal characters.
