about reached that conclusion, but in conversation with Professor Peck he tells 

 me he thinks we have two species one a thin plant (which he calls carneus) the 

 other a thick, ungulated plant with a crust (which he calls roseus) and that he 

 readily distinguishes them in the field. I place great value and reliance on field 

 observations, and atn glad that Professor Peck has called my attention to this. I 

 had specimens from Professor Burt some years ago, and he at that time made a 

 distinction between them. 



A cover marked "early specimens" contains a number of correc- 

 tions made by Professor Peck of his early determinations. As these 

 names are part of the literature of American mycology and the cor- 

 rections have not been published P append a list, with all of which 

 I agree.

Trametes piceinus is the same as Trauietes abietis of Europe, and is, as 

 generally held, a thin, conchoid form of Trauietes pini. It is well worthy of a 

 separate name, however. 



Trametes abietis of Professor Peck's determination is in my opinion a 

 trametoid form of Lenzites saepiaria, but Professor Peck does not agree with 

 me in this instance. There is no record of this specimen being fragrant. It 

 has a notation, " = Trametes odorata, fide Burt in Schweinitz's Herb," which is 

 true, but the plant has no resemblance to Trametes odorata of Europe. 



The plant determined as " Merulius Ravenelii, B. & C." is the same plant I 

 have collected and frequently received from Europe, known there now on Bresa- 

 dola's authority as " Poria taxicola, Pers. Poria rhodella, Fr. desc.! (not Icon. 

 T. 189 f. 2). " 6 



I found in Professor Peck's collection a rare plant which was hitherto 

 known in the United States only from a couple of collections in the Rocky 

 Mountains, and called by Ellis, Polyporus alboluteus. 7 Professor Peck found 

 it but once on spruce in the Adirondacks and recorded it ( 4oth Rep. ) as Lenzites 

 sepiaria var. dentifera. His specimens are a subresupinate, irpecoid form and 

 are the only collection known east of the Mississippi. 



I learned a great deal during the two weeks I spent with Professor 

 Peck, and am grateful for the information acquired and the courtesies 

 extended to me. 



CHANGE OF SEX. A young lady in the East has recently discovered that 

 Lactarius should be feminine, Lactaria, instead of masculine as mycologists for 

 a hundred years have supposed. She probably thinks it is feminine because it 

 gives milk. 



6 As Bresadola puts an exclamation mark after Poria rhodella, I think it would have been 

 better to have adopted that name. It appears to me there should be two doubtful marks put 

 after Poria taxicola. One, because it has little resemblance to Persoon's figure. The other, 

 because 1'ersoon described it as " immarginatum " and the most prominent character is its 

 broad, white margin. I would use a name after which I felt like placing an exclamation 

 mark rather than a doubtful one however "prior" the latter may be.
