2. Lecidea protabacina Nyl.; Hasse, Bull. South. Calif. Acad. 2: 60. 1903. 
Thallus crustaceous, of reddish brown, approximate (mostly) or scattered, turgid, 
strongly convex, smooth, shining squamules, rounded, or angular by pressure, occasion- 
ally fissured and lobulate, darkening at the border and beneath, KHO—, Ca(Cl1O).—; 
hypothallus black; apothecia sessile, single or several grouped, 0.5 to 2 mm. wide; 
disk black, smooth, glistening, slightly to strongly convex, the thin, smooth proper 
margin becoming gradually obscure; epithecium a thin, bluish black line; para- 
physes strict, closely coherent; thecium 44 to 48 high, almost colorless at the center 
of the disk, dark at the circumference, and indistinguishable from the thick, dark 
brown hypothecium; hymenial gelatine stained blue with iodine; asci narrowly 
clavate; spores in 8’s, oblong-ellipsoid, 11 to 12 # by 4 tod yz. 
A handsome lichen conspicuous by its chestnut brown patches from 3 to 6 cm. in 
diameter, on granite in the higher mountains. Type locality, Mount San Antonio, 
San Gabriel Range, at 3,300 meters; at the same elevation on Tauquitz Peak, San 
Jacinto Mountains; on San Bernardino Peak at 3,700 meters altitude. 
Type deposited with Doctor Nylander; duplicates in the U.S. National Herbarium 
and in herb. Hasse, 
3. Lecidea fuscatoatra Nyl. sp. nov. in litt. 
Thallus crustaceous, determinate, of approximate, brown squamules, slightly 
concave to undulate and becoming convex, round-angular or lobulate, the hypothallus 
indistinct; KHO—, Ca(ClO),—; apothecia subinnate or appressed, the disk dull 
black, flat to convex, round-angular or sinuate, the proper margin slightly lighter 
in color than the disk, thin, persistent, entire or crenulate and sinuate, subcarbo- 
naceous; epithecium continuous, bluish black or brown black; thecium colorless, 
90 to 92 » high; paraphyses strict, coherent, not all clavate at the blunt, bluish tips; 
hypothecium brown, as dark as the epithecium and thicker than the thecium; hyme- 
nial gelatine blue with iodine, the stain extending into the hypothecium; asci clavate; 
spores in 8’s, oblong linear ellipsoid, 8 to 12 long, 3 to 4 » thick. Neither KHO 
nor NO, produces change in the colors of the thecial structures. 
On granite rocks. Type locality, ‘‘Martin’s Camp, ” San Gabriel Range, at 1,600 
metersaltitude. Hasbeen collected in the Santa Cruz Mountains at 400 meters, //erre. 
Occurs at Camp Baldy, San Antonio Canyon, Los Angeles County, at 1,500 meters. 
Type deposited with Doctor Nylander in 1898; duplicates in the U. 8. National 
Herbarium and in herb. Hasse. 
4. Lecidea fumosa (Hoffm.) Ach. 
Thallus crustaceous, determinate, brown to blackish brown, squamulose; squamules 
small, flat, round, 0.5 to 0.75 mm. in diameter, scattered, to larger, approximate, 
and subimbricate, undulate and with a sinuate border; hypothallus distinct, black, 
giving to the naked eye an almost black surface to the lichen; apothecia appressed 
and sessile; disk black, flat, indistinctly pruinose or mostly naked, soon strongly 
convex, the thin black margin finally obscured; epithecium dark brown to bluish 
black, granulose, gradually paling downward; thecium colorless or pale bluish grayish, 
68 to 70 high, staining blue with iodine; paraphyses strict, closely coherent, brown 
black at the apices; hypothecium dark brown; asci broadly ellipsoid and saccate,
