MurRRILL: POLYPORACEAE OF NortTH AMERICA 347 
6. Coltricia Memmingeri sp. nov. 
A large dark brown plant with rough shaggy surface and 
short thick stipe much dilated at the base. Pileus very irregular, 
circular to dimidiate, convex to plane or depressed, 10 x I cm.; 
surface fulvous to dark seal brown, ornamented with long imbri- 
cated scales of the same color, margin alutaceous, pubescent, 
sterile, subacute, undulate: cortex corky, fragile, azonate, 0.5-1 
cm. thick, thinner towards the margin, concolorous ; tubes adnate, 
I-4 mm. long, 1-3 to a mm., umbrinous, apparently blackening 
with age, mouths circular and whitish when young, becoming an- 
gular, irregular and concolorous or darker with age, dissepiments 
entire to dentate: spores ovoid, smooth, light ferruginous, usually 
2-guttulate, 4 x 7 4; hyphae golden-yellow; cystidia none ; stipe 
central or excentric, at times confluent, very short, thick, angular 
or flattened, dilated at the base to twice its thickness above, re- 
sembling the pileus in color, surface and substance, I-3 x 3-5 cm. 
The above description was made from specimens collected at 
Blowing Rock, North Carolina, by Mr. E. R. Memminger, Sep- 
tember 1, 1901, and sent to the Underwood herbarium. Accord- 
ing to the accompanying field notes, it is a rare species and one of 
peculiar habits, being found on steep clay banks with its short 
stipe broadly spreading at the base, reminding one of a sea-ane- 
mone, and its pileus irregular and deformed by the steepness of 
its habitat and soaked with moisture from the wet clay soil and the 
surface water that trickles past it. In some ways it suggests 
forms of P. Schweinitzit, but differs widely in the color of its tubes 
and spores as well as in its shaggy surface and peculiar stipe. In 
Many ways it forms a climax to the series which begins with 
C. cinnamomea and ends with C. odesa, the plants increasing in 
size, thickness, irregularity, variability and roughness as one 
Proceeds, 
I take pleasure in dedicating the species to its discoverer, Mr. 
Memminger. The type plants are now in the herbarium of the 
New York Botanical Garden.
