tinguish the present species. The spores are described by 

 Phillips as smooth and granular within, and this is the con- 

 dition in which they are generally found ; but in the per- 

 fectly mature condition they are certainly verruculose ; this 

 stage is clearly seen in Karstens' specimens in Fung. Fenn., 

 n. 144.

 p. 209 ; Sacc., Syll., viii. n. 702 ; Phil., Brit. Disc., p. 219. 



Usually scattered, sessile, hemispherical and closed at 

 first, then becoming nearly plane, somewhat fleshy, 24 mm. 

 across ; disc vermilion with a tinge of pink or flesh-colour, 

 externally and the margin clothed with short, brown, rigid 

 hairs, the marginal ones thick-walled, more or less ventricose, 

 acute, 1-2-septate, 60-90 x 8-9 /z ; cortex parenchymatous, 

 cells large ; asci cylindrical, apex obtuse, 8-spored ; spores 

 obliquely 1-seriate, hyaline, continuous, broadly elliptical, 

 ends very obtuse, for a long time smooth, finally minutely 

 warted, 18-21 x 14-15 yu,; paraphyses septate, the broadly 

 clavated tips filled with red granules.

Distinguished by the short marginal hairs and the broadly 

 elliptical spores.
