HASSE—LICHEN FLORA OF SOUTHERN CALIFORNIA. 45 
On a dead stump of Platanus racemosa in the Santa Monica Mountains; on denuded 
oak wood in the Tehachapi Mountains, at 1,500 meters altitude. Eastern and southern 
United States and northern Europe. 
31. Lecidea turgidula Fries. 
Thallus thin, sordid white, effuse, of small globules forming a here and there obso- 
lete crust; apothecia sessile, scattered or grouped and conglomerate; disk blackish 
brown, turgid, convex, soon immarginate; epithecium not granulose, grayish, darker 
than the hypothecium; thecium and hypothecium also gray; paraphyses adglutinated 
(thecium about 40 » high, with iodine blue); asci clavate; spores in 8’s, ellipsoid, 10 
to 12 » long, 3 to 5 w thick. 
On bark of Pseudotsuga, Yosemite Valley. 
32. Lecidea coarctata (J. E. Smith) Nyl. 
Crust whitish to ash-colored, furfuraceous-squamulose, areolate or the squamules 
scattered, KHO—, Ca(ClO),—, our lichen differing in this want of reactions from the 
European form according to the authors cited; apothecia small, dispersed, innate or 
adnate, the disk papillate, flat to planoconvex, reddish brown to blackening, occa- 
sionally with a pulverulent, spurious thalline margin; epithecium yellowish, gran- 
ulose; thecium about 120 # high, colorless; asci inflated-clavate or oblong-cylindric; 
spores ovoid, 20 to 23 » long, 11 to 12 » thick. 
Frequent on earth or rocks. Throughout the United States; in Africa; tropical 
America and Europe. 
It differs somewhat in the thallus and of the resulting forms described by authors 
we have: Forma elachista (Ach.) T. Fries, the thallus consisting of thinly scattered 
areoles—on earth, Los Gatos, Herre; and forma obtegens T. Fries, with the thallus 
thick, spreading, granulate-pulverulent, the disk red brown—on earth, Santa Monica 
Range. 
33. Lecidea granulosa phyllizans Zahlbr. Beih. Bot. Centralbl. 18: 159. 1902. 
‘“Thallus in margine lobatus, lobis subcartilagincis, rotundatis, incisis vel inciso- 
crenatis, in centro plicato-verruculosus, cinerascenti-albidus, subpulverulentus, 
KHO lutescens, Ca(ClO), bene erythrinosus, nunquam leproso-fatiscens. Apothecia 
primum plana, disco livido- vel ochraceo-fuscescente, demum nigricantia et immar- 
ginata. Conceptacula pycnoconidiorum copiosa, ubique in superficie thalli sita, 
punctiformia, globoso nigra, madefacta fuscescentia, semiimmersa; perithecio dimi- 
diato; fulcris exobasidiis; basidiis anguste lageniformibus, dense congestis, subverti- 
cillatis vel verticillatis, pycnoconidiis bis vel ter longioribus; pycnoconidiis bacillari- 
bus, medio hinc inde parum angustioribus vel uno apice leviter latioribus, rectis vel 
subrectis, apicibus obtusis, 7-9 4 longis et 1.2-1.5 4 latis. 
“Ad terram inter muscos et Cladonias in declivibus occidentalibus montium San 
Gabriel, c. 1700 m. [Hasse no. 742].’’ 
34. Lecidea xanthococcoides Zahlbr. Bull. Torrey Club 27: 644. 1900. 
‘“Thallus tenuis, ruguloso-granulatus vel verrucosus, pallide cervino-fuscescens, 
KHO—, Ca(ClO),—, non corticatus, hyphis non amyloideis. Gonidia protococ- 
coidea, globosa, 10-18 » diam. Apothecia parva (0.2-0.3 mm. lata), sessilis, nigra, 
opaca, primum modice concava vel plana, margine tenui, integro subnitidoque cincta, 
demum convexa et immarginata. Excipulum et hypothecium fuscum. Hypothe- 
cium obscure fuscum, NO;—, KHO nubes fuscescentes effundens. Hymenium 
160-180 » altum. I coerulescens, dein obscure fulvescens. Paraphyses conglute- 
natae, tenues. Asci oblongo- vel ovoideo-cuneati, 8-spori. Sporae ovales vel oblongo- 
ovales, obtusae, simplices, hyalinae, 12-15 » longae et 5.5-6 » latae, episporio tenui. 
“Habita ad Lecideam xanthococcam accedit, sed structura interna apotheciorum ab 
ea longe distat. Lecidea hypomelaenae Ny]. affinis. 
“Ad truncos Coniferarum in montibus San Bernardino, circa 1,700 mt. s. m.”’
