BURT THELEPHORACEAE OF NORTH AMERICA. XII 97 



buliform and sometimes wholly flabelliform, but occasionally 

 a gathering shows both infundibuliform and flabelliform speci- 

 mens. The soft texture of the pilei like filter-paper or like 

 wash leather the large, cylindric, non-incrusted cystidia, and 

 large elongated spores are a good combination of characters for 

 the recognition of S. aurantiacum independently of the yellow 

 color. Lloyd gives Thelephora spectabilis and Stereum xanthel- 

 lum as synonyms of S. aurantiacum, and this seems quite prob- 

 able according to the original descriptions of these species, but 

 he does not state that he has studied the authentic specimens; 

 I have not been able to examine them. 



Unless there is more than one edition of Gaudichaud's ' Voy. 

 Urania Bot.,' there is an error, as noted by Lloyd, in the citation 

 by Fries in 'Epicrisis,' followed by later authors, of a figure of 

 T. aurantiaca by Persoon. Dr. Farlow kindly searched for me 

 for such a figure in his copy but without success.
