POLYPORACEzE 
IOI 
P. squamosus ( squama , a scale—from the scaly pileus), 
“ Dryad’s Saddle.” Plate XXXIII. 6. 
P. fan-shaped, developing from a snbglobose, blackish 
knob, 6-12 in. or more across, pale yellow, with large 
adpressed dark scales. F. thick, white, firm. Pov. minute 
at first, becoming angular, torn and decurrent, yellowish 
white. 5 . excentric or lateral, short, thick, corky, black at 
the base. “ This species sometimes attains to an enormous 
size. My esteemed friend, Dr. Hooker, relates an instance, 
given him by Mr. Hopkirk, of one which measured 7 ft. 5 in. 
in circumference, and weighed, after having been cut four 
days, 34 lbs. avoirdupois. It was only four weeks in attain¬ 
ing the above size, gaining thus an acquisition of weight of 
above 1 lb. 3 oz. in the day ” (Greville). Common on stumps 
and trunks, especially elm and ash. Smell disagreeable, not 
appearing in win. 
P. elegans (from its elegant shape). Plate XXXII. 1. 
P. 2-4 in., often angular, pliant at first, soon hard, smooth, 
shining, pale yellow, or dull orange. T. minute, yellowish 
white, often decurrent to the black part of the stem. 
S. J-i| in., slender, excentric or lateral, smooth, pallid above, 
abruptly black below, rooting. Frequent in sum. and aut. on 
stumps and trunks, especially birch. The var. nummularius 
is smaller (P. less than 1 in.), with a regular even margin. 
P. varius, occurring chiefly on ash, and P. picipes (disc chestnut 
colour) for the most part on willow, are closely allied species, 
difficult at times to separate from the above. 
P. umbellatus (the many stems and pileoli form an umbel), 
“ Umbellate Polypore.” Plate XXXII. 4. 
A rare species, which is delineated as an example of the 
complexity of the sporophore in some members of the family. 
Numerous umbrella-shaped dingy pilei (£-2 in. diam.), with 
elongated whitish stems (upon which the minute white pores 
are decurrent), spring from a common, thick, root-like base, 
forming a dense tuft 4-9 in. across, which might easily at
