BERKELEY'S TYPES OF FUNGI. 475 
below into a short stout stem-like base; hypothecium and ex- 
cipulum formed of slender interwoven hyphe; asci cylindrical, 
apex obtuse and not coloured blue by iodine, base short and 
narrowed ; spores 8, obliquely 1-seriate, elliptic-oblong, ends 
obtuse, usually 2-guttulate, hyaline, smooth, continuous, 11-12 
X7 u; paraphyses numerous, very slender, cylindrical, closely 
septate throughout their length.

Journ. Linn. Soc. (Bot.) vol. x. (1869) p. 369; Sace. Syll. viii. 
n. 909. 
On dead twigs and bark. Cuba (Wright, nn. 373 & 374). 
Remarkable in having the paraphyses closely septate through- 
out their length.

Gregarious ; sessile or shortly stipitate, closed at first, at length 
almost or quite plane, margin usually slightly incurved ; disc 
whitish, ochraceous, or yellow, externally pale and minutely 
furfuraceous, up to 1 mm. broad and about the same high; 
hypothecium and excipulum formed of hyaline interwoven hyphe 
which run parallel in the cortex and end in short slender parallel 
hyphe at the margin; asci cylindrical, apex obtuse, pedicel 
narrowed ; spores 8, irregularly 2-seriate or sometimes almost 
obliquely 1-seriate, hyaline, continuous, smooth, 3-4-guttulate, 
fusiform, ends rather pointed or the apex sometimes obtuse, 
18-22 x 6-7 u; paraphyses numerous, about 2 thick, hyaline, 
tips only slightly thickened. 
Hymenoscypha Luburni, Phillips, Brit. Disc. p. 135. 
On branches of laburaum (Cyfisus Laburnum). Menmuir, 
N.B. (Rev. M. Anderson). 
Usually on decorticated branches, the bark apparently thrown 
off by the fungus, as is the case with Corticium comedens. Im 
some iüstances, however, the fungus grows on the bark itself, 
which then remains on the branch. 
Superficially resembling Helotium salicellum, which, however, 
differs in the ultimately septate spores and in the margin of the 
ascophore not being furnished with a minute fringe of parallel 
hyphe.
