 Phialea ampla Ellis & Ev. Bull. Torrey Club 24: 135. 1897. 



Apothecia gregarious, stipitate, or subsessile, obconic, or 

 clavate at first, at length expanding, 3-4 mm. in diameter and 

 shallow cup-shaped, externally pale-yellow, farinose-pubescent, 

 or minutely striate, the margin involute; hymenium lemon- 

 yellow; asci clavate-cylindric, reaching a length of 110 /x and a 

 diameter of 6 n; spores 1-seriate, overlapping, narrow-ovoid, 

 3.5-4 X 11-12 m; paraphyses filiform. 



On decaying wood of Salix. 



Type locality: Mt. Paddo [Mt. Adams], Washington.

 been examined. While these are described as stipitate, mature 

 plants appear to be sessile.
