imberbis, Europe, Bulliard. This was dug up by Quelet and stated to be same 

 as Polyporus salignus. If it is true and we can not say that it is not, Bulliard could 

 not do much boasting of the accuracy of his figure t/445, f. 2, which has more re- 

 semblance a lichen than to Polyporus salignus. 



impolitus, Central America, Fries. Xo type exists. 



inamoenus, India, Montagne = Polyporus' gilvus, the thick, indurated form. 

 We use it as a convenient designation for this form but do not consider it as dis- 

 tinct, even as a form. 



inconspicuus, South America, Miquel. Unknown to me. Alleged to be same 

 as zonalis. 



induratus, Africa, Berkeley. Type destroyed. 



inflatus, United States, Ellis = Polyporus volvatus. 



inonotus, Europe, Karsten = Polyporus rheades teste Bresadola. No specimen 

 seen by me. 



intercalaris, Brazil, Berkeley. Type is the merest rubbish. Endorsed now 

 as being Polystictus versatilis, but I would as soon believe it is a new species. 

 It is nothing. 



investiens, Europe, Desmazieres. He sent a specimen under this name to Per- 

 soon who endorsed it as "Bol. abietinus, De Cand. not Dicks, and Pers." It is 

 Polyporus amorphus but shows that Persoon knew the plant before Fries named it. 



Irpex, Europe, Schulzer. Changed by Fries to Polyporus Schulzeri and only 

 known from drawing in Fries' collection and if I am not mistaken that was 

 from Kalchbrenner. It is supposed now to be the same as obtusus of the United 

 States. 



isabellinus, United States, Schweinitz = unknown. Xo specimen exists. 



isidioides, Africa, Berkeley = Polyporus scruposus, form of Polyporus gilvus. 



Jamaicensis, Jamaica, Murrill. Based on one collection which I should 

 refer to thick form ot Polyporus cuticularis. 



Jelinekii, Tahiti, Reichards = Polyporus zonalis teste Bresadola. Type at 

 Wien not seen by me. 



Karstenii, Europe, Saccardo, change of Polyporus simulans q. v. 



Keithii, England, Berkeley. Type a little piece about size of a finger nail. 

 It is one of the two species that turn red in drying, viz., either Polyporus fragilis 

 or small frustule of Polyporus mollis. 



Kerensis, Africa, Passerini. Specimens unknown to me. Description reads 

 like Polyporus ochroleucus which occurs in Africa. 



Kymathodes, Europe, Rostkovius, t. 24 seems from the picture to be Polyporus 

 amorphus. Fries maintained it as a species distinguished from amorphus by its 

 gray pores, and gave a picture. Such a plant is not known now. 



Laburnum, Europe, Opiz. Xomen nudum. 



labyrinthicus, United States, Fries, name change of Sistotrema spongiosum 

 of Schweinitz. Xo type exists either at Philadelphia, Upsala or Kew but there 

 is no doubt in my mind that it is the curious plant now known as Polyporus obtusus. 

 It may have been Polyporus delectans. Fries and Berkeley both had specimens 

 and both commented on this unusual species, but neither preserved specimens. 



Lawrencii, Tasmania, Berkeley = Polyporus gilvus. 



laxus, Europe, Orth. Unknown to me. Reads like it might be Polyporus 

 obtusus. 



leptopilus, Java, Levillie. Xo type found at Leiden. Cfr. Letter 36. 



leucocreas, Australia, Cooke = Polyporus Eucalyptorum. Cooke described it 

 as having flesh "suberose firm and tough" (sic). In his specimens the flesh is re- 

 markable for its very soft, crumbly and fragile nature, more pronounced than in 

 any other species known to me. 



Leveillei, Africa, Patouillard = Polyporus ochroleucus, old, effete. 



libocedrus, United States, Von Schfenk. This is the same as Polyporus amarus 

 and a prior name. Xo type exists and we have used the latter (and later) name 

 for reasons stated on page 330. 



ligneus, Central America, Murrill as Trametes. This appears the same plant 

 to me on comparison as Polyporus nivosellus and both I believe to be thick specimen 

 of Polyporus Calkinsii. 



Lindheimeri, Texas, Berkeley = Polyporus adustus "known only from the 

 type locality." 



Ludovicianus, United States, Patouillard = Polyporus cuticularis.
