Thallus “pale ochroleucous,” thickly crustaceous, darkening with age. 
Apothecia numerous, crowded, the thecial structure composed of a stroma 
of several apothecia surrounded by a turgid, persistent thalline margin; 
disk dull black but densely pruinose and so concolorous with the thallus, 
from round to angular, variously difform; thallus at the circumference 
inclining to become lobular and limited by a dull black hypothalline line; 
epithecium subgranulose and but little darker than the thecium; this latter 
is o. 140// high, pale sordid yellow giving no reaction with iodine ; paraphyses 
interwoven, slender; hypothecium dark brown; asci clavate, thick walled; 
spores in eight’s, oblong ellipsoid with blunted ends, brown, 6 to 8 locular, 
the cells cylindric, length of spores 0.020 to 0.030// and 0.005 to 0.007 h thick. 
The gonidial layer is composed of Chroolepus , a algae, the cells are irregu- 
larly round or oblong, forming a branching structure. Thallus with KHO 
no reaction, with Ca (Cl O) 2 the cortex gives a reddish, the medullary layer 
no reaction. 
Type locality “San Diego, Dr. E. Palmer.’’ It occurs near Newport, 
Orange Co., on Lycium Californicum Nutt., and the writer recently found 
it on the same host at Point Loma near San Diego, possibly Dr. Palmer's 
locality. Like its relatives Roccella , Dendrographa and Dirina, it evinces 
a predilection for a maritime location (A. Zahlbruckner, Bulletin Torrey 
Bot. Club, 27, Dec. 1900, p. 642 and O. V. Darbishire, Monographic Rocel- 
lorum, 1898, 40).

Thallus thin, smooth, leaden, grey or dull ashy-grey, finely rimose, 
areolate,no reaction with KHO or Ca (Cl O) 2, with determinate outline and 
a pale hypothallus; apothecia one or sometimes two in an areole, slightly 
elevated, minutely crateriform, roundish or mostly irregular in shape, and by 
the fissured thalline marginappearing stellate ; disk black ; thecium colorless; 
paraphyses slender, branched and interwoven; asci cylindric-oblong, 0.120 
to 0.140// long, 0.032 to 0.036// thick; spores in eight’s, ellipsoid, pointed or 
acuminate at each end, 0.032 to 0.042// long and 0.014 to 0.022// thick, the 
endospore mostly smooth or scarcely wrinkled ; reaction of paraphyses with 
iodine yellow and only the asci blue.
