of this very singular plant. When large it exactly resembles a piece of 
beeve’s liver. In the figures cited above the under surface appears of 
very different colours, which Bulliard attributes to the presence or 
absence of pink coloured roses which close up the mouths of the tubes, 
but are detached before the seeds are poured out. This may in part 
account for the change, but it may be observed that the tubes themselves 
are also of different colours, viz. green, and brown red. Bull. 464, 497, 
Bolt. 79, Mich. 60, andSchaeff. 117, 118. The figure of Micheliis excel¬ 
lent, and the structure of the tubes did not escape his penetrating eye, as 
appears by the dissected figures at the bottom. He remarks that the 
pileus is rusty red, the flesh blood red, the tubes dirty dull yellow, bor¬ 
dered at the mouth. Mich. p. 119. This plant attains its growth in a few 
days, and is of short duration. Bull. Lobes elliptical, generally issuing 
from a short stem. In infancy it is viscid, pulpy and exuding on being 
pricked a bloody water: colour deep red. When mature the upper side 
becomes rough and hairy, and turns blackish red or deep chocolate. The 
underside does not assume the form of pores till a late period. It appears 
at first cream coloured, and is studded very beautifully with pearl-coloured 
pimples, interspersed with some of blood red. 
The pores and tubes are extremely minute, resembling needles crowded 
together, nor are the apertures of the tubes discernible without being 
magnified. They are scarcely half an inch deep. The flesh of the plant 
then appears dry and stringy. Mr. Stackhouse.

Fixed by the pileus, the tubes uppermost. 
Pileus the colour and consistence of a cow’s hide, but softer, upon which 
are fixed the tubes, not united and contiguous, but separate. Tubes, the 
central ones the longest, some near half an inch long. It grows in patches 
of various sizes, and no determinate shape. Colour white, to buff, 
browner with age, and black in decay.
