tuberculate or angular, subglobose to ovoid, 4-5 /a wide ; hyphae 
hyaline, smooth, somewhat thin-walled, collapsing when dried, 
recovering quickly in KOH, running longitudinally in compact 
portion and forming an intricate tangle in spongy portion, easily 
separable in KOH, slender, uniform, septate with simple clamp- 
connections, segments extremely long, 3.5-4 /a wide, branching

On ground in woods, in autumn. 
The type specimens were collected at North Elba, N. Y., by 
C. H. Peck, state botanist of New York, after whom the species 
is named. The specimens are in the writer’s herbarium and a 
portion oi the same collection is in the New York state herbarium 
at Albany. The species is not known outside of the original col- 
lection.

The type specimen of the species is to be found at Upsala 
marked in Fries’s handwriting “ Hydnum geogenium Fries. Up- 
saliae.” With it are specimens collected by Lindblad at Upsala 
in 1857, also specimens sent by P. A. Karsten from IMustiala in 
1866. All of these agree in their characters and are identical 
with specimens collected by C. PI. Peck in New York.® There 
appears to be no doubt that the species belongs in the genus Hyd- 
“ It seems probable that this combination has already been made by Karsten 
but we have not been able to locate it. 
’The name is cited by Fries, but we cannot find that the species has ever 
been described.
