Bankeri, United States, McGinty. Based on a specimen in Schwcinitz' her- 

 barium which Banker, our celebrated Hydnum expert, had published as being 

 Hydnum strigosum (sic), and discovered it to be a "new genus" of Hydnaceae (sic). 

 It has more relation to a honeycomb than it has to a Hydnum. In appreciation 

 of such scientific work. Prof. McGinty named it Polyporus Bankeri. The plant 

 is Polyporus hispidus with large split pores. 



Biretum, Australia, Kalchbrenner. No specimen found by me in any museum. 

 From the description it is more probably Polyporus fruticum which grows in Aus- 

 tralia, and would about impress Kalchbrenner in this way. 



Brenningii, South America, Hennings = Polyporus osseus teste Bresadola in a 

 letter. The type at Berlin would be well named "osseus" for it is "hard as a bone." 



breviporus, Australia, Cooke = a thin specimen of Polyporus gilvus. 



Brisbanensis, Australia, Berkeley mss. = Polyporus ochroleucus. 



Broomei, Rabenhorst, Europe. Exsiccatae Xo. 2004 type = Polyporus undatus. 



brunneus, United States, Schweinitz = Polyporus radiatus (cfr Letter 50). I 

 doubt if the little frustule at Kew, however, is the same. 



Burtii, United States, Peck. No type exists. Murrill guesses that it is Poly- 

 porus adustus, which seems from description to be a good guess. 



caeruleus, Europe, Fries' Hymen, p. 549. Based on an old picture ninety 

 years ago (Fl. Dan. t. 1963) and I think it still rests on it, and nothing else. Poly- 

 porus caesius, is the only "blue" sessile Polyporus any one knows in Europe, or 

 elsewhere as far as I know. 



caesiellus, Borneo, Cesati. Unknown. Guessed by Saccardo to be related 

 to Polystictus versicolor. Not if its pores are "ferrugineus". Probably Polyporus 

 gilvus or something similar. 



caesio-coloratus, Europe, Britzelmayr. No one but Britzelmayr ever found 

 any species in Europe like Polyporus caesius except Polyporus caesius. 



caesio-flavus, South America, Patouillard. Unknown to me. Except as to 

 spores like Polyporus cretaceus in Section 81. In the process of compiling it in 

 Saccardo, the spores increased threefold in size, from 3-4 x 1-1 % to 10-10>2 x 3-4. 



caesiosimulans, United States, Atkinson. Unknown to me. I have thought 

 that it is possibly based on Polyporus semisupinus of this pamphlet though the 

 spores do not at all accord. If it is a species, it is surely a rare one in the United 

 States. Morgan records that semisupinus (or nivosus as he calls it) turns green in 

 spots when bruised, and I have noted same thing. This is a character of Atkinson's 

 species. 



callimorphus, Africa, Leveille. Type at Paris is Polyporus licnoides. Recent 

 determination from Philippines I think not the same. 



candidus, South America, Spegazzini, = Polyporus conchoides which when 

 fresh is "candidus". It becomes "carneus" in drying. 



Caprae, Europe, Britzelmayr = nothing known about it. 



carneo-fulvus, South America, Berkeley = Polyporus gilvus. I use the name 

 to designate form with slight reddish cast. 



carnosus, Europe, Patouillard. Unknown to me and I think only known 

 from a single collection. The description suggests subscssile lucidus. 



carpineus, Europe, Sowerby. t. 231 = a yellowish form of Polyporus adustus. 



cartilagineus, Celyon, Berkeley = Polyporus durus. Type at Kew. Cooke 

 compiles this in Australian Handbook as having "substance white". It is as black 

 as his hat. 



caseicarnis, South America, Spegazzini. Unknown. Seems from description 

 very similar to Polyporus Eucalyptorum. 



caseosus, Brazil, Patouillard. White. Flesh crumbly. Section 81 probably,, 

 but unknown to me. 



castanophilus, United States, Atkinson = Polyporus croceus. So referred 

 by Murrill who had no specimen as far as I found at New York. Long who is quite 

 familiar with Polyporus croceus says Atkinson's plant which he has seen is the same. 

 I have seen no specimen but I do not question it, as the description accords, and 

 Atkinson seems to discover everything that is bright enough color to draw his atten- 

 tion, to be a "new species". 



cerebrinus, England, Berkeley. Type a single specimen, surely nothing normaL 

 Endorsed now as being a myriadoporus form of Polyporus amorphus but it is hardly 

 worth guessing at the origin of such abnormal things.
