Stroma stipitate, discoid, upper surface reddish-grey, rather coarsely 
and sparsely mammillate from the projecting perithecia, 2-4 mm. 
diam. ; stem slender, of equal thickness throughout, 3-4 mm. long, 
more or less immersed in the substratum ; perithecia ovate, ostiola

-about 125 x 12 /^; spores 8, obliquely i-seriate, elliptical, subinaequi-
