HASSE—LICHEN FLORA OF SOUTHERN CALIFORNIA. 107 
6. Ramalina farinacea (L.) Ach. 
Erect or pendulous, light yellowish or grayish greenish, early dividing into narrow, 
linear, flattish, faintly longitudinally lacunose laciniw, gradually acuminate above, 
the margin beset with an almost continuous row of soredia; apothecia (rare) marginal, 
subpedicellate, not over 1.5 mm. wide, the tips not deflected above the apothecia; 
disk concolorous, concave; thalline margin finally obsolescent; spores oblong-ellipsoid, 
straight or lightly curved, 18 to 17 » long, 6 to 7 p thick. 
Frequent throughout on bushes, trees, and fences. Common in North America and 
Europe. 
7. Ramalina pollinaria Ach. 
Thallus tufted, erect, flaccid, pale greenish and pale greenish gray, about 2 cm. high, 
the lacinize compressed, longitudinally furrowed, glaucescent, narrowing and lacini- 
ately cleft into linear lobes above, the larger bursting into sorediate lobules; apothecia 
not found. 
On bushes and branchlets of trees in canyons of the Santa Monica Range. 
8. Ramalina yemensis (Ach.) Nyl. 
A sterile specimen collected by Mr. 8. B. Parish at Leche Creek, San Bernardino 
Mountains, has been determined as such by Doctor Stizenberger. It is 2 to 2.5 cm. 
high, tufted, flaccid, the laciniae compressed, minutely lacunose and longitudinally 
furrowed, dichotomously divided, the narrowed ends furcate; some of the lacinis 
with semiglobular black brown tubercles, composed of loose hyphe and brown granular 
matter; spermogones not seen. The plant is very similar to Hvernia prunastri. 
9. Ramalina crinita Tuck. 
Erect or subpendulous, generally densely tufted, compressed, linear-laciniate to 
oroadly linear, the laciniz deeply divided, both surfaces alike, shallow-furrowed, lon- 
zitudinally lacunose and occasionally fenestrate, the margins of the lacinie loosely 
beset with black, long, simple or forked fibrille, the cortex or medulla giving no 
reaction with KHO or Ca(ClO),; apothecia lateral and subterminal, in the latter 
vase the tip of the lacinia deflexed immediately above the apothecium, subpedicellate, 
3 to 8 mm. wide; disk concolorous, concave, then flat and undulate; thalline margin 
persistent, entire, at first concolorous, later darkening; epithecium continuous, sordid 
pale yellowish greenish; thecium colorless, 44 to 56 high; paraphyses coherent; 
asci clavate, 40 « long, 10 # thick; spores 8, straight and curved, 12 to 16 y long, 3.5 
io 4 yw thick; all hymenial structures blue with iodine. 
On shrubs, Lower California; on Euphorbia misera, near San Diego, Orcutt; on 
Lycium californicum, Point Loma, near San Diego. The lacinis are from 2 to 10 cm. 
in length. 
10. Ramalina menziesii Tuck. 
Thallus tufted, erect or pendulous, rigid, the laciniw linear, sparingly divided above, 
shallow-lacunose and furrowed lengthwise, attaining a length of from 3 to 6 and 8 cm., 
neither cortex nor medulla giving reaction with KHO or Ca(ClO).; apothecia sessile 
and pedicellate, marginal, from 2 to 7 mm. wide; disk pale ochroleucous, concave 
to flat, saddle-shaped and recurved; thalline margin erect, subentire, at last ob- 
tiolescent; epithecium faint yellow, granulose; thecium 52 » high, blue with iodine; 
paraphyses adglutinate, strict; hypothecium thin, colorless or faint yellowish; asci 
inflated-clavate; spores 8, 12 to 18 » long, 3.5 to 7 » thick, oblong, slightly curved, 
bilocular. 
Frequent on shrubs and branches of trees, ascending the mountains to about 800 
ineters. ; 
The typical plant has flat, compressed laciniz, reticulate with shallow ridges; but 
there occurs a form with glaucous thallus, without reticulation, but canaliculate, a 
iransition to canaliculata as it were.
