4, Heppia despreauxii (Mont.) Tuck. 
Thallus of pale olive green squamules, these small, orbicular, or attaining a width 
even of 6 to 7 mm., the larger deeply incised and lobed, attached by the entire lower 
surface to the substrate; apothecia innate, from one in the smaller to a dozen in the 
larger squame; disk depressed, flat, circular, dull brown when dry, brick red when 
moistened; thecium 130 to 140 » high, colorless or pallid yellow in places; epithecium 
subcontinuous, yellowish; paraphyses loosely coherent, the tips not colored nor 
thickened; hypothecium pale yellowish, almost colorless; asci saccate, about equal- 
ing the thecium; spores 8, large, oblong-ellipsoid, 16 to 22 » long, 8 to 10 y thick, the 
exospore thin; hymenial gelatine with iodine sordid blue, no change with KHO. 
On earth, widely dispersed; San Bernardino, Parish; Santa Monica Range. Through- 
out the United States; Europe. 
5. Heppia leptopholis Nyl.; Hasse, Lich. South. Calif. 10. 1898. 
Squamules mostly orbicular, coarsely pseudoparenchymatous throughout, 1 to 2mm. 
wide, concave or flat, yellowish olive green, above finely reticulated and fissured, 
the entire under surface attached to the substrate by loose hyphe; apothecia innate, 
not exceeding 0.5 mm. in width, disk at first little more than punctiform, red, finally 
larger, round, papillate, flush with the thallus, a complete absence of a proper margin or 
parathecium; epithecium continuous, yellowish orange, the coloration occupying about 
one-fifth of the thecium, this otherwise colorless, 180 to 184 » high; paraphyses loosely 
coherent, slender, the tips not colored nor thickened; hypothecium faintly yellowish 
tinged, almost colorless, of about the thickness of the thecium; asci nearly equaling 
the height of the paraphyses, upper half of the membrane thickened, the cavity grad- 
ually attenuate upward, wine bottle shaped; spores small, regularly globular, 5 to 6 # in 
diameter; with iodine the asci staining blue, especially above, the rest of the hymenial 
structure yellow, the epithecium dark orange. 
‘‘Affinis Heppiae psammophilae,’’ Nylander. 
On earth. Type locality, foothills of Santa Monica Range near the Soldiers’ Home. 
Also on Santa Catalina Island. 
Type deposited with Doctor Nylander; duplicates in the herbarium of the New 
York Botanical Garden, the U. 8. National Herbarium, and herb. Hasse. 
6. Heppia hassei Zahlbr. Beih. Bot. Centralbl. 13: 157. 1902. 
Squamules appressed, about 1 mm. in diameter, orbicular, lobate-crenate to irregu- 
larly round, mostly approximate, slightly ascending at the margin, homoémerous, 
pseudoparenchymatous-cellular, the Scytonema gonidia glomerulose-concatenate; 
apothecia solitary in squamules, immersed; disk red brown, flat, primarily punctiform, 
then dilated to about 1 mm. wide, papillate-roughened; thalline margin thin; hypo- 
thecium narrow, yellowish; exciple thin; thecium pale roseate, 120 to 127 phigh, with 
iodine vinous red; asci numerous, ventricose-saccate, 100 to 120 » long, 22 to 27 # thick, 
the membrane above calyptriform, thickened; epithecium reddish; paraphyses em- 
bedded in hymenial gelatine; spores numerous, oval, decolorate, simple, 5 to 7 » long, 
3.5 to 4 » thick, the epispore thin. 
Ongranite. Type locality, Palm Springs at the eastern base of the San Jacinto Range. 
Type deposited with Dr. A. Zahlbruckner and in herb. Hasse. 
1 Prof. B. Fink, Lichens of Minnesota, Contr. U.S. Nat. Herb. 14: 150. 1910, believes 
this species to be identical with Heppia despreauxii. However, aside from the general 
coarseness of the latter and its one squamule often containing several apothecia, the 
difference in the spores suffices to establish the authenticity of Nylander’s H. terrena,
