the margin or marginate all around and pendant by a short 
stem attached to the upper side near the margin, drying very 
thin, somewhat translucent, buffy brown to fuscous, with upper 
surface more or less minutely velvety and somewhat veined; 
hymenium inferior, forming rather deep, angular pores about 
1-2 mm. in diameter and about half as deep in the dried her- 
barium specimens, with the more prominent walls somewhat 
radiating from the stem; basidia flexuous, transversely septate, 
30-45 x 4L$-5V$ w; spores hyaline, even, simple, curved, 9-12 
x 4-5l$ y 
Dried NET IT 2-4 em. in diameter and 4% mm. thick. 
On dead wood. West Indies and Mexico. December to 
April. 
This species is distinguished by having its hymenium in ir- 
regular folds and pits, as in Merulius tremellosus, to so marked a 
degree that dried specimens are likely to be regarded as a dark 
species of Merulius, from which the slender, transversely sep- 
tate basidia readily separate it. 
Specimens examined: 
Exsiccati: Smith, Central American Fungi, 142. 
Cuba: C. Wright (in Curtis Herb.). 
Jamaica: Balaklava, A. E. Wight, 306, 309, and 342 (in Farlow 
erb.). 
Mexico: Jalapa, C. L. Smith, in Smith, Cent. Am. Fungi, 142; 
Motzorongo, J. G. Smith (in Mo. Bot. Gard. Herb., 480); 
Orizaba, J. G. Smith (in Mo. Bot. Gard. Herb., 4066). 
There occurs throughout North America on prostrate, de- 
eaying trunks and limbs of Populus tremuloides a common an 
conspicuous species which I have determined during many years 
for my correspondents as Phlebia strigoso-zonata (Schw.), for I 
had compared my collection with the type of Merulius strigoso- 
zonatus Schw. in Herb. Schweinitz. The combination Phlebia 
strigoso-zonata, with the alternative Auricularia strigoso-zonata 
(Schw.) Lloyd under his pseudonym McGinty, was finally pub- 
lished by Lloyd, Myc. Writ. 4: Letter 46:6. 1913, and regarded 
as synonymous with a species of the Far East known as Auricu- 
laria rugosissima (Lév.) Bres., as well as by other names. 
Auricularia rugosissima is known to me by the specimen from
