Haematomma Pacifica Hasse sp. nov. 
Thallus white, effuse, finely granular, KHO+yellow, Ca (Cl. 0)2-; apo" 
thecia sessile, i to 1.5 mm. wide; disk reddish brown and blood red, flat to 
lightly convex, the proper margin concolorous; epithecium subcontinuous, 
red-brown to orange, this colored layer is from 50/^ to 52/4 high ; thecium 
yellowish, ioojli to 112// high (including the colored epithecium); paraphyses 
strict, slender, some are clavate above and faint orange; asci clavate, the 
membrane thin, extending up into the epithecium; spores in 8s; acicular- 
fusiform, 36// to 56// long, 3.5/4 to 4/4 thick, straight or slightly curved, 5 
locular, arranged longitudinally parallel in the ascus, about the upper half 
of the spore, containing the septa, is of the given thickness, the rest is acicu- 
lar attenuated; hypothecium about 100/4- high, yellow, of darker hue than 
the epithecium; the white, thin thalline margin contains a few gonidia; asci 
clavate, reaching the epithecium, thin walled; iodine stains the hym. gel. 
deep indigo blue, KHO gives a handsome purple violet stain. Sperma- 
gones not seen. 
On back of Pseudosuga mac 7 'ocar'pa Mayr. Santa Cruz mountains (A. 
C. Herre), and on the same substrata in the San Gabriel mountains, Los 
Angeles County, at from 800 to 1500 m. alt. This lichen has been called 
“ off hand ” by me (a reprehensible proceeding) Lecanora elatina Ach., and 
distributed erroneously as such. It differs from the eastern L. elatina in its 
finer granular thallus, darker blood-red disk, the spores and the marked 
reaction.

ing slower than the disk; apothecia sessile, crowded, small, 0.25 to i 25mm.

margin paler, thin, entire and finally obsolete; disk and margins with 
KHO+crimson; epithecium granulose, pale yellow; thecium colorless, 56/4 to

comparatively stout, some with globular, pale yellow heads, others are barely 
thickened at the colorless tips ; hypothecium colorless ; asci clavate ; spores 
in 8 s, oblong ellipsoid, 11/4 to 15/4 long, 3/4 to 5/4 thick; bilocular and 
polari-bilocular, the loculi approximate, isthmus faint or doubtful; thecium
