260 BKITISH DISCOMYCETES. 



P. sulphureo-ccesia Schum., " Saell.," p. 432. Helotium 

 albo-luteum Karst., " Myco. Fenn.," p. 160. Lacknea 

 variecolor Gill., " Champ./' p. 83, c. i. 



On rotten wood. 



Cups 250 to 300^ broad. 



Gregarious, thickset, not adnate, waxy, rather firm, 

 scarcely 1 line broad, regular ; margin entire, denticulated, 

 closed when dry, granuliform, persistent, so slightly 

 tinged with yellow that it can scarcely be called straw- 

 coloured (Fries). 



Inserted on the authority of Sowerby's P. hydnoides, 

 quoted by Fries as this species. Having examined the 

 original specimen of Sowerby, I was unable to detect any 

 asci or sporidia. The dimensions of the sporidia are 

 from Karsten.
