The following species are represented by specimens in good condi- 

 tion, and I presume, therefore, there will be no "law" made to prevent 

 our using the names. I have arranged them alphabetically under the 

 generic names usually employed in modern books, viz: Polyporus, 

 Polystictus, Fomes, Trametes and Poria. Persoon, as is well known, 

 did not use these names (except Poria and Polyporus) but he antici- 

 pated them all except Trametes, and Fries, who brought them into 

 use, merely followed the lines laid down by Persoon.

Polyporus Pes Caprae. (From Persoon's herbarium. 



POLYPORUS. 



adustus Specimen poor but evident. 



aureolus This is amorphus as now known. Arnorphus was a Friesian 

 species, but Persoon proposed to change it to aureolus, as he stated (truly) it is 

 no more amorphous than any other Polyporus. Fries would not accept the 

 change. While he had no hesitation in changing Persoon's names if they did 

 not suit him (example, Radulum molare), the rule did not work both ways. 

 "Rules" rarely do. As Fries commanded the situation, the plant has become 

 known as " Polyporus amorphus ". 



betulinus (Box 58) as well-known. 



citrinus as Persoon called the well-known sulphureus. Box No. 379, labeled 

 "cristatus? giganteus?" by Leveille, is this plant. 



confluens Not the usual form but a specimen from Chaillet, which he calls 

 "var. pachypus". I believe it to be a form of confluens, though I have seen only 

 this specimen. It is surely not a synonym for politus, as stated by Fries. 



cuticularis It appears to me that what Persoon called "triqueter" is now 

 known as cuticularis. It is a common plant in France and must have been 

 known to Persoon, who described it, I think, as triqueter. There is no specimen 

 in his herbarium. Persoon included cuticularis in his work solely on Bulliard's
