POLYPORUS BOUCHEANUS. 



" Pileo carnoso-lento, piano inoequali Icevi dein sqidamoso, gilvo, 

 stipite excentrico curto toynentoso deorsum fuscente, poris tenuibus 

 demum alveolaribus oblongo hexagonls dentatis dilute aurantiacis, 

 Klotzsch in Linn., VIII, p. 316. Ad truncos Eetulce Cfr. Favolus, 

 cui adscripsit Klotzsch." 



Mr. J. B. Ellis in lit., March 9, 1888, says : "I have specimens of 

 Favolus from various parts of the U. S. and Canada, and they all 

 seem to me to be the same thing, and Cooke, Saccardo and -Winter, 

 to whom I have sent specimens, all call it Favolus Europaeus, Fr. I 

 suspect that F. Canadensis Klotzsch is the same thing, but I do not 

 absolutely know it to be so." On the other side Professor Charles 

 H. Peck writes me under date of Feb. 14, 1888 : "We have two or 

 three forms which have been referred by various persons sometimes to 

 F. EiiropcBiis or F. Canadensis, and sometimes to Polyporus Boucheanus. 

 One I think is F. Canadetisis Kl., as does also Morgan. Kalchbrenner 

 when living also took the same view." 



Mr. John Macoun, Botanist of Canadian Geological and Natural 

 History Survey, wrote me April 23, 1889, from Bunad Inlet, B. C: 

 "I collect two species of Favolus, one of them being F. Canadensis. 

 As far as I am aware none grow on this coast." After a number of 

 years of observation of the variety of forms which Favolus assumes as 

 it grows here, and after comparison of specimens from other localities 

 labelled Canadensis and Europaeus I am unable to find any good 

 characters to separate them. It is probable that the forms run 

 together. I believe that the tawny variety often becomes bleached 

 by exposure to the weather, and as a result we have a paler and glab- 

 rous form. Nor can I detect constant histological differences. The 

 species is considered to be the same as Merulius alveolarius published 

 by De CandoUe in Flore Francais (from 1805 to 181 5). Favolus 

 EuropcBus was published in Fr. Epicrisis, 1836-1838. Hence I have 

 restored the specific name alveolarius and call our specimens Favolus 

 alveolarius (D. C.j
