HASSE—LICHEN FLORA OF SOUTHERN CALIFORNIA. 53 
On various living barks, Santa Monica Range. New England States; tropical 
America, Cuba; Europe; Japan. 
10. Bacidia umbrina (Ach.) Branth & Rostr. 
Crust pale ash to sordid blackish olive green color, of coarse, flattened and irregular- 
shaped granules, when dry accumulated into warty, obscurely rimose elevations, 
when moistened the crust dark black green and the granules contiguous; apothecia 
subinnate to adnate, 0.25 to 1 mm. wide; disk black, plane with a thin, concolorous 
margin, later the disk becoming almost semiglobular, the margin vanishing; epithecium 
blackish brown; thecium 60 » high; almost colorless; paraphyses intricately inter- 
woven; hypothecium similar in color to the epithecium; asci inflated-clavate, the 
membrane thick; spores acicular, bowed and doubly arcuate, the ends blunt, one 
rounded, 16 to 28 nlong, 3.5 to 5 «x thick, mostly 4-locular, intertwined in the spore sack 
and thus giving the appearance of a multisporous ascus. 
On sandstone, Ballona Bluffs near Santa Monica; at Santa Barbara. Eastern 
United States; Europe. 
Our plant is the forma psotina (Fries) T. Fries with the heads of the paraphyses 
sordid olivaceous brown. 
11. Bacidia kingmani Hasse, Bryologist 14: 101. 1911. 
Thallus poorly represented by small congregated or scattered, sordid light olive 
green, imbricated squamules, or evanescent; squamules 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 persistent 
proper margin turgid, gray pruinose, generally strongly crenate-sinuose; epithecium 
subcontinuous, bluish black; thecium colorless, 88 » high; paraphyses coarse, scarcely 
thickened above, with light brown tips; hypothecium dark brown, thicker than the 
thecium; asci narrowly clavate, not reaching the epithecium, 8 to 10 » thick, often 
slightly curved, the septa indistinct; hymenial gelatine staining dark blue with 
iodine. 
On quartzose rock in the San Gabriel Range along the “New Trail” to Mount 
Wilson. Collected by Mr. C. C. Kingman. 
Type in the herbarium of the collector; duplicate in the author’s herbarium. 
TONINIA Mass. 
Thallus crustaceous-squamulose, rugose to caudate, lobate at the periphery; gonidia 
Pleurococcus; apothecia circular, sessile, biatorine or lecideine, without a lecanorine 
margin; paraphyses simple, discrete or coherent, thickened and often capitate at the 
tips; hypothecium pallid or dark; ascus membranes thin; spores in 8’s, elongated- 
ellipsoid to almost staff-shaped, parallel-bilocular to parallel- plurilocular, the loculi 
cylindric, the wall thin, without a halo; spermogones immersed, spermatia capillary 
or acicular, curved, rarely straightened.
