2. Leaia stratosa (Berk.) 
Hydnum stratosum Berkeley, Lond. Jour. Bot. 4: 307. 1845. 
Plant wholly resupinate on the under side of logs, frequently 
stratose from successive growths, spreading 2-10 cm. ; subiculum 
thin, 1-2 mm., consisting of fine repeatedly branched processes 
not anastomosing, with free subterete ends at the margin, clothed 
above, that is, between the branches and the substratum, with a 
varying thickness of a woolly umber tomentum ; substance of the 
subiculum tough, fibrous, brownish; margin irregular, lobed, fim- 
briate from the projecting ends of the branches, subfertile ; teeth 
slender, terete, tapering, acute, subflexuose, pendent from the 
branches concolorous and similar in substance, at length hoary 
from the spores, 1-2.5 mm. long, 0.2-0.3 mm. wide; spores 
globose to subovoid, white or hyaline, one or more guttulate, 
minutely рарШове, 4-7 и wide.

The type plant collected by T. G. Lea in Ohio is in the Kew 
Herbarium, England. Through the kindness of Dr. L. M. Under- 
wood comparison of our plants with the type was effected, and 
there can be no doubt as to their identity. The above description 
is drawn up from the dried specimens. We have not seen the 
fresh plant and the taste is not known. 
The plant is remarkable not only for its unique character, but 
also for the fact that in a period of over fifty years only one col- 
lector besides its discoverer has ever found it, although it would 
seem to have considerable range of distribution. So keen an ob- 
server and diligent a collector in the type region as A. P. Morgan 
became very sceptical concerning it, remarking : “There is no 
record of its ever having been found again, and Mr. Berkeley does 
not enumerate it in the notices of North American Fungi. І have 
never met with anything that would answer to it in any way. 
It is evident that the plant is rare, as is also Ив congener, here 
published for the first time. |
