140 REVISION OF THE NORTH AMERICAN HYDNACEAE 
The type of this species is a plant of the Ellis collection at 
Ше New York Botanical Garden and marked * 3716 Hydnum 
fragile Fr. det. Cooke." Тһе above description was written 
partly from the dried plant and partly from notes of Ellis 
made on the fresh plants collected at Iona, N. J. Ellis first re- 
ferred these plants to “ 27. laevigatum Fr." but afterwards, perhaps 
by the influence of Cooke, referred them to Æ. fragile Fr. and 
under the latter name they were distributed in his N. Am. Fung. 
as No. 929. Тһе plant, however, appears to be a very distinct 
thing. It is the only fleshy species I know of with pale tubercu- 
late spores, and in some of its characters it appears to stand inter- 
mediate between the genus Hydnum and the genus Sarcodon. 
The tuberculate feature of the spores, the fibrous somewhat tough 
character of the flesh, together with the general habit of the plant 
point to its affinities with the latter genus. In the dried зрес!- 
mens the anastomosing ridges connecting the base of the teeth is a 
very marked and constant character and suggests the specific name. 
Only the one collection is known. The color and habit of 
the plant are likely to cause it to be overlooked.
