172 FUNGUS-FLORA. 



excipulum and cells of cortex parenchymatous ; asci rather 

 large, cylindric-clavate, pedicel short, stout, 8-spored ; spores 

 grouped in an oblong cluster near the apex of the ascius, 

 enclosed in a common membrane within the ascus, elliptical 

 or elliptic-fusiform, hyaline, then passing through violet to 

 brown, epispore sometimes minutely cracked, 20-22 X 10-12 /x ; 

 paraphyses slender, septate, often branched from near the 

 base, slightly clavate at the tips, enveloped in yellow 

 mucus. 



Ascobolus Kerverni, Crouan, Ann. Sci. Nat., 1858, vol. x. 

 pi. 13b, figs. 7-10. 



On old cow and horse dung. 



Readily distinguished by the yellow colour of the 

 ascophore. 



Specimens examined from Cooke's Fung. Brit., ed. ii., 

 n. 399, and Renin's Ascom., n. 166. 



*# 



Ascophore minutely pilose. 



Saccobolus caesariatus. Renny, in Phil., Brit. Disc, 

 p. 297; Sacc, Syll., viii. n. 2186. 



Minute, hemispherical, white, clothed with colourless, sep- 

 tate, slender, flexuous hairs ; disc convex, papillate from the 

 exserted asci ; asci broadly clavate ; spores elliptic, purple, 

 smooth, enclosed in a common hyaline sac ; paraphyses 

 filiform, rather stout, simple or branched. 



This is an exceedingly beautiful species, very minute, 

 but, unfortunately, no dimensions are given, nor yet the 

 habitat. It resembles a pure white, sessile Lachnella, 

 (Phillips.) 



Unknown to me. 



CUBONIA. Sacc. 



Ascophore sessile, hemispherical, becoming obconic, disc 

 at length plane and studded with the projecting points of 

 the asci, externally smooth or pilose ; asci clavate, 8-spored ; 

 spores globose, hyaline ; paraphyses present.
