162 SYNOPSIS OF THE FLORA OF COLORADO. 



PARMELIA CAPERATA, Ach. Infertile. (6.) 

 PARMELIA CONSPERSA, Ach. (7.) 

 PARMELIA OLIVACEA, Ach., var. EXASPERATA, Dw. (8.) 

 PARHELIA LANATA, Kyi. Mount La Plata, at 14,200 feet altitude, 

 August 3. Infertile. (9.)

PELTIGERA CANINA, Hoffni. (13.) 



SOLORINA BISPORA, Kyi. Syn. p. 331. White-House Mountain, at 

 13,800 feet altitude, August. Perhaps, as Kyi. observes, only a variety 

 of S. saccata, from which it differs in its more urceolate apothecia and 

 thekes containing only two spores, which in the specimens before me 

 measure .054 to .110 mm. long and .027 to .040 mm. wide. Kew to this 

 continent. (14.) 



COLLEMA PULPOSUM, Ach. Infertile. (15.) 



PLACODIUM CORALLOIDES, Tuck. A small, infertile fragment. (16.) 



PLACODIUM ELEGANS, DO. (17.) 



PLACODIUM CALLOPISMUM, Ach. (18.) 



PLACODIUM VITELLINUM, (Ehrh.,) Ach. (19.) 



PLACODIUM CERINUM, Ach., var., STILLICIDIORIUM, Ach. On mosses. 

 (20.) 



PLACODIUM BOLACINUM, Tuck.! White House Mountain, at an eleva- 

 tion of 13,000 feet, August, (21.) 



LECANORA STRAMINEA, Wahl. A small, infertile fragment. (22.) 



LECANORA MURALIS, (Schreb.,) Schser. (23.) 



LECANORA RUBINA, Ach. (24.) 



LECANORA ?. A very small and imperfect specimen, belonging 



to the section Squamaria and distinguished chiefly by its large spore^, 

 which are from 4 to 8 in the thekes, and measure from .019 to .027 mm. 

 long bv .007-.008 mm. \* ide. I cannot refer it to any described species. 

 (25.) 



LECANORA SUBFUSCA, Ach. (26.) 



LECANORA YARIA, Fr. (27.) 



LECANORA BRUNONIS, Tuck.? White House Mountain, at 13,000 feet 

 altitude, August. The very small fragment seems to belong here, but 

 the spores are at length 4-locular, .015 to .018 mm. long by .004 to .005 

 wide. (28.) 



LECANORA CINEREA, (L.) (29.) 



LECANORA CALCAREA, (L.,) Somf. White House Mountain at 13,000 

 feet altitude, August. The specimens are elegantly emgurate. This 

 form has before occurred, I believe, on this continent only in Greenland. 

 (30.) 



LECANORA CHLOROPHANA, (Wahl.,) Ach. The specimens mostly deal- 

 bate. (31.) 



LECANORA XANTHOPHANA, Kyi. (32.)
