104 MR. G. MASSEE—REDESCRIPTIONS OF 
surface owing toa thin layer of the veil of the fungus adhering 
to it ; the inner membrane consists of the veil proper, and stands 
erect or curves inwards over the border of the disc. No trace of 
gonidia present. 
PLATYGRAPHA stTICTOIDES, Leighton, Lichens of Ceylon, in 
Trans. Linn. Soc. xxvii. (1870) p. 180, pl. 37. £. 387. (Pl. 5. 
figs. 1-4.) 
Ascophores gregarious, scattered or more frequently arranged 
in irregular little groups, immersed in the matrix, at first covered 
by a snow-white veil, which eventually ruptures and forms an 
irregularly torn persistent margin; cireular, elongated, or more 
or less wavy, *5-2 mm. across; dise dark grey (when dry); asci 
cylindrical, apex rounded and not at all blue with iodine, base 
slenderly stipitate, 90-100 x 8,4; spores 8, obliquely 1-seriate, 
elliptic-oblong, ends obtuse, smooth, 3-septate, septa thick, at 
first hyaline then tinged brown, the contents tinged green, 
12-14 x 6; paraphyses very slender, delicately septate, some- 
times with a short branch near the apex which is not thickened.

Cryptodiscus subreticulatus, Sace. Syll. viii. n. 2764. 
On bark. Ceylon; tropical forests south of the island 
(Thwaittes, nn. 628 & 630). 
Leighton considered the present species to be a lichen, but 
there are no gonidia, and iodine does not produce a trace of blue 
coloration on the asci or other hymeaial elements. Leighton’s 
type has been examined in the Leighton Lichen herbarrum 
which is located at Kew. The groups of apothecia are sometimes 
arranged in an irregularly reticulate manner, hence Berkeley's 
specific name. 
PLATYGRAPHA MaaytiFica, Berk. § Broome, in Journ. Linn 
Soc., Bot. xiv. (1875) p. 110, pl. 5. £.26. (PI. 5. figs. 7-9.) 
Scattered or gregarious, immersed in the matrix, and eventu- 
ally surrounded by an irregular, rigid, raised margin, formed by 
the torn and upraised epidermis of the host plant; dise at first 
covered with a thin veil, becoming naked, plane, deep orange 
colour, 15-8 mm. across, circular in outline; hypothecium 
yellowish-brown ; asci very large, clavate, apex slightly narrowed 
aud having the wall thickened, not blue with iodine, narrowed
