DODGE-LICHENS AND LICHEN PARASITES 917
RAMALINA INFLATA Hook. f. & Taylor.
Ramalina injEata Hook. f. & Tayl. in Hook. f., F1. Antarctica, 1,194; 1845. Cryptogamia Antarct.,
82 ; 1845.
Cefraria injlata Hoolr. f. & Tayl., London Jour. Bot., 3, 646; 1844.
Ramalina calicanis v. infiatam Hook. f., Handb. N. Zeal. F'l., 564; 1867.
Type: Lord Auckland's group, J. D. Hooker (Voy. "Erebus & Terror") in Taylor Herb. at
Harvard TJniversity.
Thallns about 5 cm. tall in dense clusters, dichotomously branched, branches 3 mm. in
in diameter, - ultimate branche short, 1 mm. in diameter, tips obtuse, sparingly fistulose, perfora-
"B
tions relatively small, surface shining, drying wrinkled and lightly foveate, very pale yellow when
fresh, drying ochraceous buff, spotted with dark blood-red, hollonl; cortex a palisade of gelified,
conglutinate hyphae 5-6r in diameter, withab~~f&ct very small crystals, gel yellowish green in
thin sections, golden brown in thick ones; mecha~~ical tissue not developed; algae in colonies about
3OP in diameter, cells protococcoid, $-lop in diameter, scattered in a very loose medulla of very
thick-walled hyphae about 6r in diameter, lumen about lr, forming a layer about 10OP thick, K
f uscous.
Apothecia terminal on the branches, about 6 mm. i11 diameter, disc concave to nearly plane,
yellowish glaucous, margin not elevated, exnlple smooth; amphithecial cortex, algal layer and
medulla of the same structure as that of the thallus, with smaller and fewer colonies of algae
beneath the hypothecinm which is much more densely woven of slightly more slender hyphae in a
layer about 35p thick ; thecium 55p tall ; paraphyses slender, dichotomous above the asci, ending in
slightly enlarged, gelified tips covered with cry~tals or minute granules; asci cylindric clavate.
tips thickened, 40-45 X 10-12r; ascospores hyaline, 2-celled, ends subacute, not constricted at the
septa, straight or slightly cnrved, 10-11 X 5-6p. Sperinogonia not seen.
From the structnre of the cortex ancl the absence of mechanical tissue, this species seems to
belong in sect. ~,dmaziera Stzbgr. or perhaps segregated in Cenozosda Mass. rather than in sect.
Euramalina Stzbgr. subsect. Fistularia Vainio where it has usually been placed.
Besides the type specimen described above, a small specimen frcm Macquarie Island may
belong here. It is sterile and probably young. Tho luminn in the cortical cells are somewhat larger
and coarse, brownish hyphae, very loosely inter-woven with very large air spaces fill the central
'portion, at least in the small branch sectioned.

RAMALINA BANZARENSIS Dodge, sp. nov.
Type : Macquarie Island, Featherbed Flat, Sta. $la, B.A.N.Z.A.R.E. 531.
Thallus ad 3 cm. altitudine vel major, applanatus, plus minusve dichotome ramosus, ramis 2-3
mm. latitudine, subinflatis, fistulosis, fist~dis elongatis irregulariter dispositis, frequenter ad margines
sitis, albidis, brunneo-maculatis ; cortex verus deest ; stratum chondroideum ca. 40p crassitudine,
gelifactum, hyphis ramosis, longitudinalibus cum luminibus tennissimis; stratum algarum
in ramo secto deest; pars centralis hyphis pachydermaticis, brunneis, Mr. diametro, laxissime
contextis impleta; soralia elliptica, albida, suberosa, sorediis ex paucis cellulis algarum, 5-6p
diametro, plus minusve ab pressione mutua angulosis, ab paucis stratis hypharum leptodermaticarum
tenuissimarum hyalinarum circnmdatis. Apothecia spermogoniaque non visa.
Thallus at least 3 cm. tall [perhaps more as the material is very broken, although preserved
in formalin], flattened, more or less dichotomously branched, branches 23 mm. wide except at the
