212 FUNGUS-FLORA. 



"becoming paler and smaller upwards, and ending in parallel, 

 usually 1- septate, obtuse, pale hairs at the margin ; asci 

 cylindric-clavate, apex narrowed, base stout, 8-spored ; 

 .spores irregularly 2-seriate, hyaline, continuous, narrowly 

 elliptical, ends rather pointed, but sometimes inclined to be 

 obtuse at one end, 5-8 x 1' o fx ; paraphyses slender, hyaline, 

 very slightly thickened at the tips. 



Pyreiiojiezizadigitalina, Sacc, SylL, viii., n. 147 7. 



On dead stems of foxglove. 



Specimen examined in Phillips, Elv. Brit., n. 128 (called 

 Peziza atrata, var. digitalina). 



Phillips in his description of this species — Brit. Disc, 

 p. 190 — says it is externally squamulose, but I find his own 

 specimens to be perfectly glabrous. 



Var. Smyrnii. Phil. & Plow., Brit. Disc, p. 192. | 



Gregarious, sessile, hemispherical then expanded, fleshy, 

 glabrous, pale argillaceous ; margin minutely fimbriate ; 

 asci cylindraceo-clavate ; spores 8, fusiform or cylindraceo- 

 fusiform, 3-guttulate, 10-13 x 3 /x ; paraphyses filiform. 



On dead stems of Smyrnhtm. 



Differing very little from M. dilutella (Phil.). 



Not seen. 



Mollisia dilutella. rhil., Brit. Disc, p. 191, pi. vi. 

 fig. 34. 



Gregarious, sessile, globose and closed when young, then 

 expanding, but the disc remains persistently concave and the 

 whitish margin more or less incurved, glabrous and polished, 

 greyish- white, becoming pale amber and translucent when 

 dry, hypothecium formed of hyaline, anastomosing hyphae. 

 excipulum hyaline, delicately parenchymatous, cortical cells 

 irregularly polygonal, G-8 fx diameter, becoming smaller 

 upwards, and running out into almost hyaline, parallel hyphae 

 at the margin ; asci cylindric-clavate, apex narrowed, base 

 stout, 8-spored; spores irregularly 2-seriate, hyaline, con- 

 tinuous, often slightly curved, 8-11 x 2 /x, elliptical, ends 

 rather acute ; paraphyses slender, hyaline, slightly thickened 

 at the tip.
