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 p. 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 

 obtuse, smooth, hyaline, continuotis, 1113 X 67 //.; para- 

 physes septate, apex clavate, 6 p. thick, brown, straight or

The form called Peziza viridaria, var. obscurata, Eehm, 

 Ascom., n. 452, and characterised as follows, "darker, para- 

 physes clavate, septate, brown, slightly curved ; spores 

 1 1 x 6 fi. In Bavaria," is quite included in the range of 

 variation of the typical species, in which the colour varies 

 from very pale to dark brown. Intermediate between Peziza 

 and Humaria. 



PEZIZA. Dill, (emended.) 



Ascophore sessile, but sometimes narrowed to a short, stem- 

 like base, fleshy and brittle, closed at first, then expanding 

 until cup-shaped, saucer-shaped, or in some species quite 

 plane or even convex; disc even, nodulose, or veined; ex- 

 ternally warted, scurfy, or rarely almost glabrous ; cortical
