SYNOPSIS OF THE FLORA OF COLORADO. 163 



STEEEOCAULON CONDENSATUM, Laur. ? Infertile. (37.) 



CLADONIA PYXIDATA, Fr. (38.) 



CLADONIA FURCATA, Flk., var. RACEMOSA, ib. (39.) 



CLADONIA VERMICULARIS, Ach. Head-waters of Platte Kiver, at 

 10,000 feet altitude. Spermogones and spermatia similar to those de- 

 scribed by Xylander, have occurred to nie in White House Mountain 

 specimens of this plant. (40.) 



LECIDEA CONTIGUA, Fr. White House Mountain, at 13,000 feet alti- 

 tude, August. (41.) 



LECIDEA CONTIGUA. Fr. ?, with smaller apothecia. Mount La Plata, at 

 14,000 feet altitude. (41a.) 



LECIDEA CONFLUENS, Schaer. White House Mountain, at 13,000 feet 

 altitude. (42.) 



LECIDEA ENTEROLEUCA, Fr. On twigs; the thallus lutescent. (43.) 



LECIDEA ATRO-BRUNNEA, (B.C.,) Schaer. Mount La Plata, at 14,000 

 feet altitude. (44.) 



LECIDEA LUGUBRIS, (Sornf.,) Nyl. White House Mountain, at 13,000 

 feet altitude. (45.) 



LECIDEA LAPICIDEA, Ach. A single small specimen. (46.) 



BUELLIA ALBO-ATRA, (Hoffm.,) Nyl. White House Mountain, at 

 13,000 feet altitude. (47.) 



BUELLIA GEOGRAPHIC A, -(L.,) Th. Fr. (48.) 



STAUROTHELE UMBRINA, (Wahl.,) Tuck. A few traces of this lichen 

 occurred on fragments of rocks with other lichens. (49.) 



YERRUC ARIA PYRENOPHORA, Nyl. f A single small specimen. Spores 

 2-locular, .027-.32 mm. long by .012-.14 wide. White House Mountain, 

 at 13,000 feet altitude. (50.) 



YERRUC ARIA ? Thallus hardly any. Apothecia sessile, globose, 



with a depressed artiole; perithecia black, entire 5 paraphyses indistinct. 

 Eeaction with iodine various, red. Spores 2-val., 4-pluri-locular, irregu- 

 larly muriforni, colorless or slightly fusescent, .027-.36 mm. long by 

 .015-.18 wide. The very small quantity of this which occurred is hardly 

 sufficient for its determination. It is perhaps new. (51.) 



YERRUCARIA ? Parasitic on a sterile thallus, which is perhaps 

 that of Buellia epigcea. Apothecia minute, emergent; paraphyses dis- 

 tinct capillary, not colored by iodine. Spores 4-several, acutely ellip- 

 soid, constricted in the middle, 4-locular, submuriforin, colored, .029-.38 

 mm. long by .008-.12 mm. wide. (52.) 



ENDOCOCCUS ERRATICUS, (Mass.,) Nyl. Parasitic on Placodium ele- 

 gans. The internal characteristics appear to agree with this species. 

 Paraphyses deficient. Eeaction with iodine various, red. Thekes ven- 

 tricose, polysporous. Spores 2-locular, colored, .008-.11 mm. long, by 

 .004-.5 mm. wide. Kew to this continent. (53.)
