MOLLISIA 205 



Peziza alhella With. (Arrang. Brit. PI. 4: 350. 1796) has been 

 cited by various authors including Fries as a synonym. As 

 pointed out by Phillips (Rev. Myc. 12: 140. 1890) this was an 

 error, apparently referring to Peziza albida. This species is 

 described as having apothecia .25-. 75 of an inch in diameter 

 while the species listed under this name, PezizeUa albella, is only 

 1 mm. in diameter or less.
