28 NORTH AMERICAN FLORA [VoLuME 9 
Pat. Tax. Hymén. 94. 1900. Described from collections made at Bethlehem, Pennsylvania, 
presumably by Schweinitz himself. Authentic specimens have not been found. ‘Those bear- 
ing this name may usually be referred to C. versicolor or C. hirsutulus, but the description 
calls for a plant near C. prolificans. 
Irpex epiphylla Schw. Trans. Am. Phil. Soc. II. 4: 164. 1832. Described from Beth- 
lehem, Pennsylvania. According to Berkeley and Curtis this species is not distinct from C. 
biformis. 
Polyporus arcticus Fries, Epicr. Myc. 479. 1838. Described from specimens collected 
by Wormskiold in Kamtschatka. Type not found, but evidently near C. nigromarginatus 
ot C. abtetinus. 
Polystictus nuceus Fries. Nov. Symb. 81. 1851. Described from plants collected on 
decayed trunks in Costa Rica, by Oersted. Type not found. Probably near C. sector. 
FPolystictus corrugis Fries, Nov. Symb. 82. 1851. Collected by Benzon in the West 
Indies. Type not found. Apparently not far from C. sector. 
Polystictus plumbosus Fries, Nov. Symb. 93. 1851. Described from Liebmann’s col- 
lections in Mexico. Type not found. Apparently related to C. sector. 
Polyporus Richardsonii Berk. & Curt. Jour. Acad. Phila. II. 3: 224. 1856. Described 
from Richardson’s collection in boreal North America. Apparently near C. pubescens. 
Polystictus placentaeformis Cooke, Grevillea 15: 24. 1886. Described from plants 
collected on dead poplar limbs at Carlton, British North America, in 1858. The small type 
specimens are quite well preserved at Kew. They resemble forms of C. xigromarginatus 
or C. pubescens, growing on the under side of a limb, but the pores are much too large for 
the former and the surface is too hirsute for the latter. 
24. CORIOLELLUS Murrill, Bull. Torrey Club 32: 481. 1905. 
Hymenophore small, dry, annual, epixylous, semi-resupinate; surface anoderm, usu- 
ally azonate: context white, thin, fibrous to corky; hymenium concolorous; tubes thin- 
walled, usually rather large and irregular, dentate, but not irpiciform: spores smooth, 
hyaline. 
Type species, Zrametes Sepiunt Berk. 
Pileus white or pale-isabelline. 
Surface finely tomentose to glabrous; context firm. 1. C. Sepium. 
Surface conspicuously villose to strigose; context very soft and spongy. 2. C. cuneatus. 
Pileus cinereous-fuscous, glabrous. 3. C. Sequotae. 
Pileus fulvous to latericeous, finely tomentose to finely strigose. 4. C. serialis. 
1. Coriolellus Sepium (Berk.) Murrill, Bull. Torrey Club 32: 481. 1905. 
Trametes Sepium Berk. Lond. Jour. Bot. 6: 322. 1847. 
Pileus small, dimidiate, sessile, laterally connate, narrowly attached when young, 
becoming decurrent and often effused, 0.5-1 X 1-3.5  0.2-0.5 cm.; surface white or pale 
wood-colored, finely tomentose to glabrous, subzonate, smooth or broadly radiately fur- 
rowed; margin thin or tumid, entire to undulate: context white, 1-2 mm. thick, soft- 
corky ; tubes white, 2-3 mm. long, mouths angular, uneven, irregular, sometimes slightly 
sinuous, 1-2 to a mm., edges thin, undulate to dentate, white: spores oblong, smooth, 
hyaline, 125; hyphae hyaline, 3-5 pv. 
TYPE LOCALITY: On dry fence-railsin Ohio. 
HapitaT: Structural timber and other dead wood, especially that of deciduous trees. 
DISTRIBUTION: Temperate North America. 
Exsiccatr: Thiim. Myc. Univ. 2306; Ellis, N. Am. Fungi7Z; Rav. Fungi Am. 216; Rav. 
Fungi Car. 1: 22. 
2. Coriolellus cuneatus Murrill, sp. nov. 
Pileus thin, soft, flexible, cuneate to dimidiate, imbricate, often effused, 0.5-1.5X< 
1.5-3 X 0.2-0.4 cm.; surface conspicuously villose, strigose behind, azonate or subzonate, 
white to isabelline; margin thin, tomentose: context white to pale-yellowish, soft and 
fibrose-spongy, 1-3 mm. thick ; tubes short, white to discolored, variable, 1 mm. or less in 
length, mouths angular to irregular, 1-3 toa mm., edges thin, soft, dentate-lacerate, split-
