158 REVISION OF THE NORTH AMERICAN HYDNACEAE 
notes. The distribution recorded above is based on plants posi- 
tively identified by the aid of reliable field notes. The following 
collections are also referred here, but not with certainty : Connec- 
ticut, Underwood ; New Jersey, Ellis; Alabama, Underwood. 
7. HypNELLUM ZONATUM (Batsch) Karst. Medd. Soc. Faun. 
et Fl. Fenn. 5: 27. 1879 
Hydnum zonatum Batsch, Elench. Fung. 111. 1783. 
Calodon zonatus Karsten, Ryssl. Finl. och den Skand. Half 
Hattsv. 2: 108. 1882. 
Phaeodon zonatus Schroeter, Krypt. Fl. von Schles. 3: 458. 1888. 
Plants terrestrial, mesopodous, gregarious, often confluent, 
small, cinnamon-brown with light margin; pileus subconvex to 
plane umbilicate or subinfundibuliform, irregular, thin, less than 1 
mm. thick, 1.5-3 cm. wide ; surface radiately fibrillose-striate, sub- 
pubescent, distinctly zonate with shades of brown, darker in the 
center, pink to nearly white toward the margin when fresh but 
turning more or less uniform brown when dried ; substance darker 
and more compact than surface layer, azonate, thin ; margin thin, 
acute, sterile; stem slender, subcylindrical, slightly bulbous at 
base with scarcely evident spongy tomentum, solid, pubescent, 
cinnamon-brown, 1-1.5 cm. long, 2-3 mm. wide; teeth slender, 
terete, acute, not decurrent, dark brown, less than 1.25 mm. long, 
shortening towards margin and stem ; spores subglobose, coarsely 
tuberculate, 3—4 м wide.

As these plants conform remarkably to Batsch’s figures and 
appear to correspond in all respects with his descriptions, I believe 
them to be the true М. zonatum of Batsch. They are not, how- 
ever, the plants more commonly referred to that species (f. И. con- 
crescens). The species is readily distinguished from other species 
even in the dried state. It is most closely related to H. сот 
crescens from which it can be distinguished by its small size, thin 
pileus, slender stem, and lack of tomentum. The date given is 
only for the Alabama plant.
