2. M. tremellosus Schrad. ex Fries, Syst. Myc. 1: 327. 
1821. 
М. tremellosus Schrad. Spic. Fl. Ger. 139. 1794. 
Sessile, effused-reflexed, or entirely resupinate; pileus dimid- 
iate, 0-5 x 3-8 x 0.1-0.3 cm., fleshy or gelatinous-waxy, white 
or whitish, tomentose, azonate, margin thin and acute; context 
whitish, soft, 1-2 mm. thick; tubes very short, formed by anas- 
tomosing ridges or veins, averaging 1-2 to а mm., whitish or 
somewhat flesh-colored, in resupinate forms with a wide, thin, 
sterile border. 
On old logs in woods. Common. 
Quite often the plant is entirely resupinate and probably 
always so in young stages. Тһе form of the hymenium is 
exceptionally well shown in Atkinson, Mushrooms f. 191-92. 
Besides the above species, M. lacrymans Jacq. ex Fries has 
been included in practically every list of fungi reported from 
the states east of the Mississippi River, but its frequency of 
occurrence is probably in inverse ratio to the number of times 
reported. At any rate it is to be considered as a rare fungus 
in this country. I have never met with specimens in Ohio that 
I could so refer. 
IRPEX Fries, Elench. Fung. 1: 142. 1828. 
Hymenium inferior, dentate-lacerate from the first. Teeth 
concrete with the pileus, firm, subcoriaceous, acute, reticulately 
disposed or arranged in rows, in sessile forms connected at the 
base and gill-like, or favoloid in resupinate forms.  Basidia 
4-spored. Woody, subsessile or resupinate fungi allied to 
Lenzites апа Dedalea. (Adapted from Fries, Hymen. Eur. 619.) 
This genus is sometimes included in the Hydnacee but in at 
least one of the three species here described the hymenium is not 
toothed from the first, but is decidedly poroid and shows very 
close relationships to certain species of the thin pileate members 
of the genus Polyporus, e. g., P. biformis, P. prolificans etc., in 
which the hymenium soon becomes broken up into teeth. For 
this reason and because the plants are very common in our 
woods the three following species are described and most of the 
collections usually obtained will be found to answer to one of 
these descriptions.
