TYPE STUDIES IN THE HYDNACEAE^ 
III. THE GENUS SARCODON 
Howard J. Banker 
The name Sarcodon was first proposed by Quelet in Cooke and 
QueletjClav. Syn. Hym. Eur. 195. 1878, but as no binomials were 
formed the name was not established as a genus until later taken 
up by Karsten. Whether we follow Quelet or Karsten in our 
conception of the genus, the type species is Hydnum imbricatum L. 
Sarcodon reticulatus Banker, Mem. Torrey Club 12 : 139. 1906 
Hydnum fragile Fries, Nya Svamp. in Ofvers. af Kongl. Vetensk. 
Ak. Forhandl. 1851: 53. 1852; not H. fragile Persoon, Syn. 
Meth. Fung. 561. 1801. 
The type of this species is “ Copp 3716” deposited in the New 
York Botanical Garden herbarium. The specimen was collected 
in Iona, New Jersey, and is a part of the only collection of the 
species made in this country. Specimens of the plant sent to 
M. C. Cooke were referred by him to Hydnum fragile Fr. The 
Friesian name is untenable as it is preoccupied by H. fragile Pers. 
applied to a resupinate form. No type of H. fragile Fr. was 
found at Upsala, but European plants apparently identical with 
the American form are uniformly referred there to H. fragile Fr. 
At Kew specimens were found, collected in England, identical in 
every respect with the New Jersey plants even to the adherence 
of pine needles to the pileus indicating a similar habitat. At 
Upsala there was found a specimen collected at Mustiala, Fin- 
land, by P. A. Karsten, that had all the characters of our type 
except that it had a long somewhat fusiform stem, 2X8 cm., 
raising the pileus well up from the earth. This feature has not 
been observed in any other specimens.
