7. M. pallens Schweinitz, Am. Phil. Soc. Trans. N. S. 4: 
161. 1832. Not M. pallens Berkeley, Outl. Brit. Fung. 256. 1860. 
Type: in Herb. Sehweinitz and a portion in Curtis Herb. 
Fructifications resupinate, long and broadly effused, longi- 
tudinally confluent, grown out into reflexed pilei on all sides, 
whitish, minutely tomentose, subimbrieate, inflexed; hyme- 
nium of type has dried vinaceous-russet, irregularly retieu- 
late, poroid, with shallow pores about 2-3 to a mm.; in struc- 
ture 300—400 џ thick, with the folds extended out 200 » more, 
composed of interwoven, obliquely ascending, hyaline hyphae 
31-4 р in diameter, granule-inerusted towards Ше hymenium 
and intermixed there with fine granular matter, brownish, 
sometimes turning vinaceous by action of KHO solution on 
the sections and with brownish droplets in this region in the 
permanent preparations; spores hyaline, even, flattened on 
one side, 44-5424 и. See pl. 20, f. 6. 
Fructifications were stated by Schweinitz as effused for 
15 em. The resupinate fragment without natural margin in 
Curtis Herb. is 2 em. square, and the reflexed fragment has 
the reflexed portion 7 mm. broad. 
On fallen branches. Canada to Texas, and in California. 
The general aspect, geographic range, spore characters, 
and structure of M. pallens, with the exception of the brownish 
hymenial and subhymenial zone in preparations stained with 
eosin and the vinaceous color change with KHO solution, are 
so similar to M. confluens that it seems highly probable that 
the former is a vegetative phase of M. confluens. This can
