growing on an apple tree log, referred to by Dr. B. O. Dodge in 

 his paper "Fungi producing Heart-rot of Apple Trees,"* were 

 collected at Pike pond, Rensselaer county, July 23, 1910. This 

 pond lies a few miles south of Averill Park and Sandlake villages. 

 Part of this collection is preserved in the State Herbarium at 

 Albany, where at least a portion of it bears the name Polyporus 

 Undenuoodii Murrill, which is of course an error in determination ! 

 The other portion of the Pike pond collection is in the Herbarium 

 of the Lloyd Museum at Cincinnati, Ohio. Referring to a 

 letter from Dr. C. G. Lloyd, December i, 1910, acknowledging 

 the receipt of the specimens sent with the name Polyporus 

 Underwoodii attached, he says: 



"I think Polyporus Underwoodii is correctly named, though in 

 my opinion it is only a synonym for admirahilis Pk. The stipe 

 (always short) is almost wanting, in which case it becomes 

 admirahilis. This is another instance of the variation of the 

 black markings of the stem, for in almost sessile specimens this 

 character is absent or obscure. I think the plant is very closely 

 allied to varius of Europe, in fact a specimen recently sent to 

 Bresadola was referred by him as a variety of varius Fr. It has 

 the same indurated context and same spores and is certainly 

 closely allied to varius. In this connection, I wish you would 

 please examine the type specimens of admirahilis and write me 

 if you find the spores are "globose." I think that must be an 

 error, for the plants of all these allied species, viz., varius, picipes, 

 elegans, alhiceps, melanopiis, etc., have very similar spores, 

 about 4 X 8-10 IX, and are cylindrical." 



I do not recall ever examining the spores of the type specimens 

 of Polyporus admirahilis from Maine. Dr. Lloyd records receipt 

 of my specimens in his printed letter, No. 30: 3. Jan. 191 1. 



In the vicinity of Vaughns (Hudson Falls), New York, speci- 

 mens of this showy pure white "calla lily "-like polypore has been 

 recorded on various trees during the past eleven years, viz.. 



Butternut {Juglans cinerea L.). On a partly fallen trunk, 

 leaning over Glenwood brook. The following dates: Sept. 5, 

 1904; Oct. 26, 1905; Aug. 18, 1910; Aug. 25, 191 1 (part of the
