Thallus of bullate, subverruculose squamules, fissured or lobulate, thick, reddish 
brown, discrete or forming a continuous crust, KHO—, Ca(ClO).—; apothecia single 
or rarely two in a squamule, immersed, the apex blackening, punctiform, depressed- 
umbilicate; perithecium globose, pale; paraphyses indistinct; hymenium with iodine 
vinous red; asci ventricose, cuneate at the base, 80 # long by 20 # thick; spores in 8’s, 
simple, hyaline, globose or subglobose, 10 to 12 » in diameter. 
On granite. Type locality, Palm Springs, at the base of the San Jacinto Moun- 
tains, at 150 meters altitude. 
Type deposited with Dr. A. Zahlbruckner; duplicate in herb. Hasse. 
4. Dermatocarpon miniatum (L.) Mann. 
Thallus foliaceous, monophyllous or submonophyllous, beneath centrally attached; 
fronds 2 to 3.5 cm. wide, roundish, lobed, the margin entire or crenate, pale mouse- 
colored above, smoothish, leathery brown to dark brown beneath, brittle when dry; 
apothecia immersed, minutely umbilicate; asci oblong, 80 # long, 12 » thick, the 
membrane thickened, especially at the top, leaving the cavity attenuate above; 
membrane not stained by iodine, but its contents yellow; sporesin 8’s, oblong-ellipsoid, 
14 to 20 » long, 4 to 7 # thick; hymenial gelatine blue with iodine. 
On rocks; not very common but widely distributed in our district. Yosemite Val- 
ley; Tehachapi Mountains; San Gabriel Mountains; Palm Springs. North America, 
northern Africa, and Europe. 
4a. Dermatocarpon miniatum complicatum (Swartz) T. Fries. 
Thallus foliaceous but the fronds smaller, polyphyllous and imbricated, ascending, 
somewhat cespitose; asci subcylindric, the upper part of the membrane thickened as 
in the last species, very gelatinous; hymenial gelatine with iodine violet blue, the 
asci cavities yellow, the membrane not stained; spores in 8’s, ellipsoid-ovoid, 12 to 
16 « long, 6 to 8 # thick; spermatia short, straight, apparently slightly thickened at 
the ends, 5 to 6 # long, about 1 # thick. 
On rocks; of the same distribution as the species. San Bernardino Mountains, 
Parish. 
5. Dermatocarpon intestiniforme (Koerb.). 
Endocar pon intestiniforme Koerb. Par. Lich. 42. 1860. 
Thallus polyphyllous, caespitose, creamy gray in color or sometimes with a faint 
bluish dash, the borders of the squame directed downward, forming bullose cavities 
of the coarsely areolate central part, the areoles roundish, subangular or frequently 
angular-wavy, each squamule or bulla containing mostly several apothecia; periph- 
eral squame foliaceous, expanding and imbricate; apothecia at first immersed, later 
becoming prominent, the extruding perithecium dull black with a minute ostiole, 
the immersed part soft, globular to flattened-globular, of a pale flesh color; thecium 
colorless; paraphyses gelatinous, indistinct; asci cylindric or bottle-shaped; spores 8, 
bluntly ellipsoid, colorless, faintly granular, 12 to 18 long, 6 to 9 »# thick; hymenial 
gelatine staining blue with iodine, soon changing to orange brown; KHO giving no 
reaction. 
On rocks and earth in crevices of rocks. North Fork of Matilija Canyon, Ventura 
County; Eden Hot Springs and Palm Springs, Riverside County, to the Grand Can- 
yon in Arizona. 
ENDOCARPON Hedw. 
Thallus foliaceous-squamose, both surfaces or only the upper with a pseudoparen- 
chymatous cortex; perithecium immersed or protruding with the apex simple, erect; 
thecium with oblong or rounded hymenial gonidia; proper exciple dark; paraphyses 
gelatinous; asci saccate or ventricose, 1 to 6-spored; spores oblong or ellipsoid, muri- 
form-multilocular, at first colorless, soon light yellowish brown to brown; spermatia,
