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 spectahilis 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.
