DODGE-<strong><strong>LICHEN</strong>S</strong> <strong>AND</strong> <strong>LICHEN</strong> <strong>PARASITES</strong><br />
CATII,LARIA INCONSPICUA Dodge & Baker<br />
Catillaria ,inconspicuu Dodge & Baker, Ann. Mo. Bot. Gard., 25, 548; 1938.<br />
Type : Marie Byrd Land, Edsel Ford Range, Chester Mts., P. Siple & S. Corey 9711-1.<br />
Non-assimilative portions of the thallus finely black, very inconspicuous, of coarse<br />
dark hyphae forming the cortex, medulla of more slender hyaline hyphae, loosely to compactly<br />
woven. Assimilative portions scant over areas of 1 sq. cm., greyish; cortex prominent, of small<br />
fasiigiate cells, little darkened; algal layer 55-60r. thick, cells single or in small cplonies, more<br />
or less vertically arranged ; medulla of :lender loose hyphae, branching in the sub-cortical regioii;<br />
basal layer not sharply differentiated, often confluent with the non-assimilative portions.<br />
'<br />
Apothecia up to 1.35 mm. in diameter, sessile on the assimilative areoles, pulvinate, irregular,<br />
black, scattered ; parathecium scarcely distinct ; hypothecium 20-25r. thick, hyaline, of slender<br />
periclinal hyphae, very compact; thecium 80-9OP tall ; paraphyses about lp in diameter, heads<br />
4.5r., slightly darkened, sheath rather conspicuous, branched or unbranched, slightly flexuous,<br />
epithecium about lop thick, K purple; asci 56-67 X 15-19p clavate, 8-spored; ascospores<br />
15-19 X 4-5-7p, uniseptate, long ellipsoid, rarely reiiiform or navicular, not constricted at the<br />
septum.<br />

Biatorina sect. Thalloidinta Jatta, Syll. Lich. Ital., 369; 1900.<br />
Type : Based on L. vesiclilaris Ach., L. candidahh., L. n~ammillaris Duf. and L. cmglonterata<br />
Ach., all but the last still treated as belonging here by Zahlbruckner, the last placed in I'otinia<br />
sect. Eutoninia.<br />
Thallus cartilaginous squamulose in a bullate or winkled crust, effigurate, with amorphous<br />
cortex or a palisade of thick-walled septate vertical hyphae; algae protococcoid. Apothecia<br />
sessile, with coloured or dark parathecium formed of radiating hyphae imbedded in a gel ; paraphgses<br />
simple or imbedded in a gel, often capitate; hypothecium hyaline; asci small, subventricose,<br />
tips obtuse, 8-spored; ascospores long ellipsoid to fusiform, 2-locular, hgaline, septum often not<br />
very clear.<br />
Our species is closest to the segregate Fritzea Stein ap. Cohn, Kryptog. 0. Schlesiens, 2, 2,<br />
114; 1879, based on Psora luntprophora Icorb. (Thalloidima lampropi~orz~m Miill.-Arg.) in the<br />
apothecia being innate in the thallus when young, then emerging and becoming almost<br />
immarginate at maturity. I have not seen sufficient to form an opinion on the validity of Fritzea.<br />
Zahlbrwkner, while citing the generic name as a synonym of Tminis sect. Thalloidinra, leaves the<br />
single species so far referred to Fritzea in Lecidea sect. Psora.<br />
THAL~IDIMA KERQUFLENSIS Dodge, sp. nov.<br />
Type : Kerguelen, Greenland Harbour, B.A.N.Z.A.R.E. B177-39.<br />
Thallus crustosus, effiguratus, marginibus crassis lobatis, albidus glauoo-g;iseus, centro rimosoareolatus;<br />
cortex 55r. crassitudine, hyphis pachydermatic;.~, subverticalibus, dense contextus dein<br />
gelifactus et subamorphus; algae protoooccoideae, coloniis rotundatis, cellulis 7-SP diametro,
