Humaria viridaria. Mass. 



At first globose and closed, then hemispherical, finally 

 almost plane, sessile, %-l^ cm. across, rather fleshy, greyish, 

 pale or dark brown ; excipulum parenchymatous, cells 

 irregular, 10-16 yu, diameter; externally almost smooth 

 upwards, furnished with hyaline septate hyphae near the 

 'base, that form a delicate, cottony stratum round the base 

 of the ascophore ; asci cylindrical, apex somewhat truncate, 

 8-spored; spores obliquely 1-seriate, broadly elliptical, ends 

 <obtuso, smooth, hyaline, continuous, 11-13 X 6-7 /a; para- 

 'physes septate, apex clavate, 6 /x thick, brown, straight or 

 ■curved.

 from very pale to dark brown. Intermediate between Peziza
