sidered Hydnum strigosum Sw. These were at once recognized 

 as being the same as Leaia piperata. A copy of Persoon's Icones 

 et Descriptiones Fungorum was examined during the past sum- 

 mer and it was evident that the two species were identical. In 

 the pubhcation of the writer's Contribution to a revision of the 

 North American Hydnaceae,* it seemed necessary to include 

 Hydnum strigosum Sw., although the species was not well under- 

 stood, since there had been found in the Schweinitz herbarium a 

 peculiar plant that had been referred to the above species, and 

 correctly, so far as could be determined. On the evidence of 

 the Schweinitz specimen and the supposedly correct interpretation 

 of Swartz's description, the species was placed in the genus Stec- 

 cherinum and inadequately described, as was intimated at the 

 time. It now seems doubtful if the Schweinitz specimen is the 

 true Hydnum strigosum Sw., but a reexamination of the plant 

 would be necessary to positively settle the question. Be that as 

 it may, it is now evident that the Swartzian species was wrongly 

 disposed of. 



With the settling of the question as to what constituted the 

 true H. strigosum. Sw., a new problem arose. The writer had 

 made his species Leaia piperata the type of a new genus. With 

 the determination of the identity of his plant with the Swartzian 

 species, it is evident that the latter becomes the type of the 

 genus. However, in 1879, P. A. Karsten had established the 

 genus Gloiodon on Hydnum strigosum Sw. and two other species. f 

 Ten years later he established the monotypic genus Sclerodon on 

 H. strigosum Sw., quoting his own genus Gloiodon as a synonym. J 

 In accordance with the principles here followed, § the genus must 

 be known as Gloiodon. 



The correct nomenclature of the two species here discussed, 

 with their synonomy, would, therefore, be as follows : 



Gloiodon strigosus (Sw.) P. Karst., Medd. Soc. Faun, et Fl. 

 Fenn. 5 : 28. 1879.
