DODGE-LICHENS AND LICHEN PARASITES 87
prominent; parathecinm 100-110~ thick, carbol~aceous, not extending below the thecium; hypothecium
not clearly differentiated from the medulla and thccium except more deeply staining:
thecium about 75-9OP tall; paraphyses slender, not conspicuously branched, eseptate, iiot
thickened at the tip, ending in the bluish epithecial gel; asci [oblong cuneate, nearly as long as
I
the thecium, thin-walled, 8-spored] ; ascospores distichous, hyaline, ellipsoidal 10-14 X 7-9~.
[Spermogonia immersed, spherical, tip blaclr; wall fnligineous, dimidiate; spermatiophores
fasciculate, subulate cylindric, shorter than thc spermatia which are moderately curved or hamate,
18-24 X 1~1. Data in brackets I] supplied from the original clescription as our material is too

Type: Icerguelen, Observatory Bay, A. E. Eaton (Venus Transit Exp.).
Thallus fuliginous to black, sometimes stained ochraceous, rimose areolate, more or less determinate
with a very narrow black margin; ecorticate; algae protococcoid, occupying most of the
thallus, cells up to 7~ in diameter. Apothecia semi-immersed, 0-4-0-5 mm. in diameter; parathecium
carbonaceous, extending about one fourth the distance under the hypothecium, about
110~ thick, continued across under the hypothecium by a line of fuliginous cells, 5 5 thick ~ at the
centre and thinning to 2 0 thick ~ at the margin, extending about halfway up the hypothecium;
hypotliecium about 110~ thick at the centre, thinning to the margin, of essentially vertical hyphae,
branched and anastomosed; thecium 7 5 tall; ~ paraphgses about 1.5~ in diameter, fasciculately
branched, and brown above the asci, cutting off spherical cells at the tips, about 3p in diameter;
asci 8-spored, clavate, 40 X ZIP; ascospores monostichous or nearly so, hyaline, short ellipsoidal
(often appearing spherical in the ascus), 7-8 x 4-6~ while still in the ascus (8-10 X 7~ jide
Nylander).
B93, B17.7-15, and B177-26 appear to belong here from the microscopic characters of the
apothecia, but the thallus is variegated bluish-black and white, the latter staining yellow with
KOH, resembling a thin state of L. subassentiens without the marginal lobules.
