CIBORIA. 277 



On fallen, decaying involucres of sweet chestnut. 



The spores, as in C. 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 C. fa-ma, but distinguished by the strongly curved spores, 

 and bv the different habitat. 



Specimens examined in (Jooke'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, subglobo.se and closed, then becoming 

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

 entire ; disc brown, depth of colour variable, externally paler, 

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

 11 5 cm. long ; hypothecium brownish, and like the h}*aline 

 excipulum formed j of intricately interlacing hyphae, cortex 

 parenchymatous, cells brown; asci narrowly cylindric- 

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

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

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

 elliptic-oblong, 1421 x 4-5 /x,; paraphyses slender, very 

 slightly thickened at the tips.

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



On falling, decaying fruits of Angelica, also on decaying 

 seeds of Helianthius, Bidens, &c., 



Distinguished from C. ochroleuca by the smaller size of the 

 ascophore, very slender stem, continuous spores, and different 

 habitat. 



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

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 | mm. thick, often wavy ; hypothecium brown, 

 and along with the hyaline excipulum, composed of stout, 

 intricately interwoven hyphae, cortical cells parenchyma- 

 tous, 14-20 fj. diameter; asci cylindrical, apex rounded, 

 8-spored, spores obliquely 1 -seriate, hyaline, continuous,
