figure (t. 462) which is such a poor figure that Persoon never recognized it. 

 However, there is a specimen in his herbarium which I would refer to cuticularis, 

 labeled by Persoon " Boletus cuticularis, Bull.?" 



frondosus as well known. 



fumosus (Box 65) which has dark pores and would generally be referred to 

 adustus. Persoon records "Odor gratus". 



hispidus (Box 40) as well known. 



Juglandis well known now as squatnosus. 



laccatus (Box 350) as Persoon called the well-known lucidus. 



leucomelas a small specimen as now known, I think. 



levis There is no specimen of levis now although there evidently was at 

 one time, for the label is attached to a ferruginous Poria with a second label, 

 " medulla panis affinis ", the latter evidently the correct one. Levis was a pileate 

 species, "passim ad Salices", and its identity, even as a tradition, has been lost 

 entirely. 



Pes Caprae a nice specimen (Fig. 332) from Mougeot. Persoon described 

 it as "vert-jaunatre". 



radiatus Persoon evidently took radiatus from Fries' work. What is known 

 as radiatus to-day, Persoon called ''triqueter var. alneus ". There are, however, 

 two very poor specimens in the herbarium labeled "radiatus." Both are very 

 poor and doubtful, and I think neither is radiatus.

Polyporus Rheades. 'From Persoon's herbarium. 



RHEADES. (Fig. XXX.) Ce sont des specimens excessivement intres- 

 sants car 1'espece d'e Persoon fut entierement mal interpreted par Fries. Rheades 

 est la plante identique qui fut appelee vulpinus par Fries; c'est une espece rare 

 mais fortement marquee poussant sur le peuplier. Persoon ne rencontra jamais 

 la plante lui-meme, mais il en recut deux bons specimens de Tussac. Ils sont 

 en bon etat (dans la boite 4) sauf que les spies recouvrant le pileus sont usees. 

 Fries a classe le Rheades parmi less Spongiosi, section i laquelle il n'appartient
