142 FUNGUS-FLOKA. 



Ombrophila clavis. Cke., Grev., viii. p. 84; Phil., 

 Brit. Disc., p. 324, pi. x. fig. 62 ; Sacc., Syll., viii. n. 2531 ; 

 Kehm, Disc., p. 478. (figs. 13, 14, p. 156.) 



Crowded, gregarious, or scattered, somewhat gelatinous, 

 "but rather firm when moist, very variable in form, obconic 

 or pileate and distinctly stipitate, disc plane or convex, stem 

 slender or stout, from |-1 cm. across, entirely pallid or with 

 a more or less decided purple or lilac tinge ; excipulum com- 

 posed of rather loosely interwoven hyphae ; asci cylindrical, 

 8-spored ; spores] obliquely 1-seriate, hyaline, smooth, ellip- 

 tical, ends in some cases obtuse, at others narrowed and 

 almost fusiform, 10-16 x 4-5 /x ; paraphyses septate, slightly 

 thickened at the tips ; hypothecium formed of thin, densely 

 interwoven hyphae. 



Peziza clavus, A. & S., Comp., p. 306, t. xi. f. 5. 



On twigs, leaves, &c., in wet places. 



Specimens determined by Berkeley examined, also Kab.- 

 Wint., Fung. Eur., n. 3771. 



Very variable in form and size, stem sometimes almost 

 absent, sometimes short and stout, and in rarer cases 1-2 cm. 

 long, and very slender; ascophores sometimes irregularly 

 nodulose, at others symmetrical and almost plane, and alto- 

 gether resembling a flat-headed nail. Distinguished from 

 small specimens of Hclotium, &c., by being gelatinous when 

 moist, and by the structure of the excipulum. 



Ombrophila helotioides. Phil., Grcv., vol. xvi. p. 94 ; 

 Sacc., Syll., viii. n. 2544. 



Stipitate, solitary or caespitose, capitulate, pallid, glabrous, 

 subgelatinous ; disc convex, margin thin, undulating ; stem 

 cylindrical, a little flexuous ; asci cyliiidraceo-clavate; 

 spores 8, narrowly fusiform, straight, or slightly bent, 5- 

 guttulate, 20-26 X 2-3 -5 /A; paraphyses filiform, hardly 

 thickened at the apices. 



On dead stems of Equisetum in water. Autumn. 



Cup 12 lines broad, the whole plant 2-4 lines high, stem 

 \ line thick. It differs from 0. clavus in the spores (Phillips). 



Unknown to me. 



Ombropliila rudis. Phil., Brit. Ditc., p. 322; Sacc., 

 Syll., viii. n. 2537.
