CIBOEIA. 277 



On fallen, decaying involucres of sweet chestnut. 



The spores, as in G. ochroleuca and other species, are often 

 furnished with delicate protoplasmic threads at the ends, and 

 these sometimes terminate in a minute, globose head. Allied 

 to G. firma, hut distinguished by the strongly curved spores, 

 and by the different habitat. 



Specimens examined in Cooke's Fung. Brit , ed. ii., n. 367 ; 

 Phil., Elv. Brit, n. 32, and Eehm, Ascom. n. 606. 



Ciboria subularis. Sacc, Syll., viii. n. 828. 



Ascophore stipitate, subglobose and closed, then becoming 

 saucer-shaped or nearlj- plain, thin, fragile, glabrous, margin 

 entire ; di:>c brown, depth of colour variable, externally paler, 

 '2-5 mm. across : stem slender, wavy, coloured like the pileus, 

 1-1 • 5 cm. long ; hypothecium brownish, and like the hyaline 

 •excipulum formed^ of intricately interlacing hyphae, cortex 

 parenchymatous, cells brown; asci narrowly cylindric- 

 clavate, apex slightlj- narrowed, 8-spored; spores obliquely 

 l-seriate, or partly 2-seriat6 near the top of the ascus, hyaline, 

 smooth, continuous, straight, sometimes 2-guttulate, narrowly 

 «Uiptic-oblong, 14—21 x 4r-5 /j.; paraphyses slender, very 

 slightly thickened at the tips.

Hymerwscypha subularis, Phil., Brit. Disc, p. 122. 



On falling, decaying fruits of Angelica, also on decaying 

 seeds of Selianthius, Bidens, &c.. 



Distinguished from G. ochroleuca by the smaller size of the 

 ascophore, very slender stem, continuous spores, and different 

 habitat. 



Specimen in Herb. Berk., Kew, accepted as typical.

 Ehem, Krypt.-Flora, Disc, p. 755 ; Sacc, Syll., viii. n. 822. 



Gregarious, stipitate, at first closed and pear-shaped, then 

 expanding until almost plane, thin, rather pliant ; disc pale 

 brown, externally paler, 3—10 mm. broad ; stem 1—4 cm. 

 long, up to I mm. thick, often wavy ; hypothecium brown, 

 and along with the hyaline excipiiluni, composed of stout, 

 intricately interwoven hyphae, cortical cells parenchyma- 

 tous, 14-20 /i, diameter; asci cylindrical, apex rounded, 

 ■S-spored, spores obliquely l-seriate, hyaline, continuous,
