6 /«- to 12 /A in diam. ; the medullary layer is composed of hyphae 
loosely interwoven, especially at the axis, and 2 a«- to 3 thick. 
Apothecia, from 1 to 8 in a lobule head, are immersed, marked by a 
punctiform perforation of the cortex, sometimes slightly dilated to 
not exceeding 0.25 mm in width and depressed ; disk dull brown ; 
the flesh- colored, flattened-globular hymenium is beneath the gonidial 
layer. Thecium 140 m high, colorless ; paraphyses loose, coherent, 
slender ; hypothecium colorless or of a pallid yellowish tint ; asci 
quite numerous, upper part slightly attenuated, the membrane about 
3 thick throughout, 112 m long, 28 to 32 thick, the immature 
asci are shorter with solid thickened tops. Spores globular, 4, 5 m 
to 7 in diameter (the liberated spores giving the larger measurement), 
24 to 32 being contained in the ascus ; hymenial gelatine with iodine 
a pale indigo blue, changing to sordid pale greenish. KHO gives a 
bronze red color to the gonidial layer; spermatia not seen. The 
species differs from others with similar spore measurements in the 
shape of the thalline lobules. 
On quartz in Rubio Canon, San Gabriel Range, near Pasadena, the 
type locality. Collected by Mr. C. C. Kingman. The same species 
has since been found near Riverside by Mr. F. M. Reed. 
I take pleasure in naming this latest addition to the West- American 
Heppiae for Dr. A. Zahlbruckner. 
Type deposited with Dr. A, Zahlbruckner and type duplicate in 
herb. Hasse. 
Bacidia Kingmani spec. nov. 
Thallus poorly represented by small, congregated or scattered, 
sordid light olive-green, imbricated squamules, or evanescent, these 
when present about 0.5 mm wide, flat or conchiform ; hypothallus 
indistinct. Apothecia sessile or substipitate, 2 to 3.5 mm wide, disk 
dull black, flat to convex, often with a faint grayish bloom, the per- 
sistent proper margin turgid, gray pruinose, generally strongly crenate- 
sinuose. Epithecium subcontinuous, bluish-black; thecium colorless, 
88 high ; paraphyses coarse, scarcely thickened above and with 
light brown tips ; hypothecium dark brown, thicker than the thecium ; 
asci narrowly clavate, not reaching to the epithecium and 8 to 10 
thick ; spores colorless, blunt fusiform, 4-to 5-locular, 14 to 20 
long, 3.5 to 4 thick, often slightly curved, the septa indistinct; 
hymenial gelatine with iodine dark blue. 
On quartzose rock in the San Gabriel Range along the “New 
Trail “ to Mt, Wilson, collected by Mr. C. C. Kingman. 
The following species have been collected by Dr. J. N. Rose in 
Lower California : —
