332 B.A.N.Z. ANTARCTIC RESEARCH EXPEDITION<br />
The structure of the primary thallus clearly distinguishes this species from any species of<br />
Cladonia with which I am familiar, otherwise it might be taken for an extremely yomg member<br />
of the C. fimbriata group.<br />

Type : Kerguelen, Christmas Harbour, J. D. Hooker (Voy. " Erebus & Terror ") , also the<br />
type of C. squanzosa v. nunu, in Taylor Herb. at Farlow Herbarium, Harvard University.<br />
C. fimbriata v. mimr was based on collection from St. Paul Island (Voy. "Novara"), not seen.<br />
Primary thallus of small, imbricate squamules, 2-3 mm. in diameter, about 250p thick, lobes<br />
narrow and short, mostly appressed, forming a compact crust in young colonies, finally almost<br />
disappearing as the old podetia proliferate, tilleul buff, or somewhat darker, whitish when dry;<br />
cortex about 15-18p thick, a mixture of thick-walled, periclinal and vertical hyphae, conglutinate<br />
but not fully gelified, suggesting a pseudoparenchyma, walls in the central portion slightly<br />
brownish; algal layer about 55p thick, cells spherical to slightly elongate, arranged in snb-<br />
vertical rows, up to 8p in diameter, protococcoid ; medulla of thick-walled, loosely woven, more or<br />
less periclinal hyphae, &5p in diameter, occasionally with an algal cell or small colony below<br />
the compact algal layer, and deposits of crystals.<br />
Podetia up to 1.2 cm. tall, arising from below the algal layer, cylindrical with a shallow<br />
cup, at first farinose sorediate, soredia developing in situ to minute isidiose verrucae and occa-<br />
sional minute squamules; the stalk about 2 mm. in diameter; the cup becomes abruptly dilated,<br />
up to 12 mm. in diameter, mostly smaller, margin smooth, slightly brownish with groups of<br />
spermogonia and sessile apothecial initials, finally becoming proliferous at the margin in a
