468 MR. G. MABSEE— REDESCRIPTIONS OF 
gone. An examination of fresher material will be necessary to 
settle this point. 
Cenanatum Corensot, Berk. in Hook. f. Fl. Nov. Zeal. ii. 
p. 201 (1855), and in Handb. N. Zeal. Flora, p. 629; Sacc. 
Syll. vii. n. 2329. 
Ascophores gregarious or scattered, covered at first by the 
epidermis of the host-plant, then erumpent, oblong at first, and 
with the opposite sides of the excipulum ineurved, then expanding 
and becoming orbicular and concave; substance thin, soft; 
2-3 mm. across; disc pale watery-grey, often with a tinge of 
pink, externally and the margin glabrous, dark brown; hypo- 
thecium and excipulum hyaline, delicately parenchymatous, 
passing into large, dark brown cells at the cortex ; asci cylindric- 
clavate, apex slightly narrowed, and not tinged blue with 
iodine; spores 8, irregularly 2-seriate, continuous, hyaline, 
smooth, elliptical, often slightly inequilateral, 7x4 p; para- 
physes slender. 
On dead leaves of Phormium tenax. New Zealand (Colenso, 
n. 4828). 
The species is not a Cenangium, as considered by Berkeley ; 
the soft, watery substance, glabrous exterior, and not being 
fasciculate or cespitose in habit, are against this idea. On the 
other hand, the fungus is a typical Pseudopeziza, and should in 
future stand as P. Colensoi. 
The elongated form of the fungus when young is caused by 
growing between the parallel rigid vascular bundles of the host- 
plant; when it first bursts through the epidermis, it opens by a 
long, narrow slit, as in Hysterium, but gradually expands and 
becomes circular and widely open. 
ParELLARIA PROXIMA, Berk. $ Broome, in Ann. $ Mag. Nat. 
Hist. ser. III, vol. vii. (1861) p. 450, tab. 16. fig. 18; Massee, 
Fungus-Flora, vol. iv. p. 101. (Pl. XVIII. figs. 18, 14.) 
Gregarious, sessile, and semi-immersed in the matrix ; plane, 
then slightly convex; black, often with a tinge of olive 
or brown when moist; 1-3 mm. across; hypothecium dense, 
brownish, composed of indistinct, more or less parallel, dingy 
olive hyphz; asci clavate, gradually narrowing from the apex 
into a slender pedicel, apex rounded, wall thin, not at all tinged 
blue with iodine, about 140x144; spores 8, obliquely 1-seriate
