The type of the above described species is in the writer’s her- 
tinct from Hydnum fuligineo-violaceum Kalch., although Kalch- 
brenner’s Hydnum fidigineo-violaceum, though not with entire 
confidence. Since then specimens have been received from Abbate 
G. Bresadola which that distinguished mycologist collected in 
Trient and compared with Kalchbrenner’s type. These plants 
are manifestly very different from the American forms described 
above. At Upsala two specimens were observed collected in 
Hungary and contributed by Kalchbrenner himself. These plants 
appeared to have the characters of Bresadola’s specimens, but 
were smaller, approaching in size the American plants. They 
confirmed the diagnosis that the above described species is dis- 
tinct from Hydnum fidigineo-vioJaceum Kalch., although Kalch- 
brenner’s figure^ closely resembles the appearance of our plants.

There is probably no type of H. laevigatum Sw. in existence. 
At least I have not been able to locate any of Swartz’s specimens. 
In the European herbaria very little material was found referred 
to this species and none that could be regarded as having much 
weight in determining the authentic characters of the species. 
The American plants which we have referred to this species con- 
form well to the few European plants that we have seen and 
appear to have all the characters ascribed to the species. 
Hydnum bubalinum Pers. is represented in Persoon’s herbarium 
at Leyden by a single specimen sent by Chaillet. The plant ap- 
pears to be the same as our specimens of H. laevigatum Swartz.
