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, 2—4 mm. 

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

 externally and the margin clothe(J with short, brown, rigid 

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

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

 cells large ; asoi 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 jj.; paraphyses septate, the broadly 

 clavated tips filled with red granules.

On damp ground in shady places. 



Distinguished by the short marginal hairs and the broadly 

 elliptical spores.

 Phil., Brit. Disc, p. 220 ; Sacc, Syl., viii. n. 726. 



Gregarious or somewhat caespitose, hemispherical and 

 -closed when young, then expanded and often wavy, bright

 septate, pointed, brown hairs, 150-300 x 7-10 ft,; cortex 

 parenchymatous ; 4-8 mm. across ; asci cylindrical, apex 

 obtuse, 8-spored ; spores obliquely 1-seriate, continuous, 

 hyaline, ornamented with delicate raised anastomosing ribs, 

 enclosing very minute polygonal pits, 18-21 x 12-14 /x; 

 paraphyses septate, tips thickened and containing yellow 

 granules.
