,Ilargil~, disc zoo11 plane, cinnamon rufous at first, then chestnut brown; amphitheci~~m 25OP<br />
tllick, extending over the disc; cortex 354Op thiclt; algal layer as in the thallus; parathecium<br />
35-;5.ip thick, of slender periclinal hyphae extending part way under the hypothecium and merging<br />
with the medullary and algal tissues; hypothecium about 7Sp thick, thinning to aho~~t 35p<br />
Iletlr the margin, of slender, densely woven hyphae; thecium 150-170p tall; paraphyses simple,<br />

Crozet Archipelago: Possessioil Island, American Bay, 13.A.N.Z.-4.R.E. B2O-3, 1320-5.<br />

Heard Islaiicl : Atlas Cove and Corinthian Bay, B.A.N.Z.A.RrE. B140-11, B140-12.<br />
A very small, young thallus amoiig mosses may belong here. It has the geiieral aiiatomy of<br />
l'on~mrk., but the cortex is less developed and is covered by the gelified remains of a tomentnm.<br />
The algae fill nearly the whole thickness of the thallus.<br />

COCCOCARPIA Pers.<br />
Coccoccn.piu Pers. ap. Gaudichaud, in Freycinet., Voy. "Uranie" Bot., 206; 1826.<br />
Type : Coccocarpia ntolybduea Pers. ap. Gaudich.<br />
Thallus squamose to foliose with dark or light colonred rhizinae, corticate on both surfaces;<br />
upper cortex pseudoparenchymatous from thin-walled, large periclinal hyphae, without tomen-<br />
tum; algal layer of coiled chains of Scytonenza in thin sheaths; mednlla of thin-walled, somewhat<br />
conglutinate hyphae not sharply differentiated from the lower cortex of more or less septate,<br />
periclinal hyphae. Apothecia superficial, sessile or somewhat constricted below; amphithecium<br />
absent; parathecinm corticate of large-celled pseudoparenchyma, wit'h large septate periclinal<br />
hyphae within; medulla lacking; hypothecium light or dark; asci 8-spored; ascospores hyaline,<br />
unicellular, spherical to ellipsoidal-fusiform, thin-wallecl. Spermogonia in warts on the'thallus,<br />
spermatiophores frequently septate; spermatia straight, elongate-cylindric.<br />

100-16OP crassit~~diiie, filarnentibus scytonematum et hyphis verticalibus septatis 4p cliametro,<br />
cellulis 8-10p longitudine; medulla compacta, funiculis hypharum dense intertexta; cortex inferior<br />
7-lor. crassitudine hyphis periclinalibus septatis.<br />
Thallus foliose, up to 2 cm. in diameter, cent re more or less areolate, cracks principally radial,<br />
marginal lobes cuneate incised, grayish olive, surface dull, without soredia or isidia; hypothallus<br />
