Colorado Fungi, (new kpe< ies.)- -By ('has. II Peck. — The species of fungi here 

 described were collected in Colorado by Mr. T S. Bramtegee, and forwarded to me for 

 examination by Mr. A'. 8. Rau, of Bethlehem, Pennsylvania. 



Spir.Kuoi'sis Raui, /'/,-.— Spots indefinite, brown; perithecia numerous, gregarious, 

 minute, phomatoid, sub-membranaceous, black, .006-.007 inch in diameter; spores obo- 

 vate or oblong, colorless, .00065 -.00075 incli long. 



Living leaves of Artemisia scopvlorum, Gray. 



Leoythka speciosa, Pk. —Spot.- suborbicular, one to two lines in diameter, yellow ; 

 sori lew, crowded, prominent, liypophyllous orange-colored; abortive spores elongated, 

 curved, obtuse, nearly cylindrical; spores sublogosc or elliptical, .001-0012 inch long, 

 rough, the endochrome brighl orange. 



Living leaves of Buhus deliciosus, Ton-. 



This is probably the early or Uredo form of some species of Phragmidium which 

 should besought later in the season, it is distinguished from its allies by the deep 

 orange color of the sori, and the narrow elongated abortive spores. 



^Eciditjm Brandegei, Pk. — Peridia amphigenous, scattered or aggregated, some- 

 times seriately placed, elongated ; spores subglobosc, orange colored, .0008-.001 inch in 

 diameter. 



Living stems and leaves of Asclepias verlicillata, L. 



The peridia resemble those of ./</. Thalictri, hut the spores and habit of the plant 

 are quite different. It occupies the stem and leaves in patches of considerable extent 

 and changes the aspect of the hosl plant. 



xEcioium HEMisPHiERicuM, Pk. — Peridia prominent, scattered or crowded, hemis- 

 pherical, opening by a small aperture ; -pores orange, subglobose or elliptical, .OOOS-.OOI 

 inch long, the epispore thick, hyaline. 



Living stems and leaves of Mulgedium pnlchellum, Nutt. 



The peridia are generally more scattered on the stem than on the leaves, the whole 

 lower surface of which is often occupied by them. 



^Ecidium porostjm, Pk. — Spots none; cups crowded, deep-seated, broad, wide- 

 mouthed, occupying the whole lower surface of the leaf to which they give a porous 

 appearance; spores orange-colored, sub-angular, .0008-.001 inch in length. 



Living leaves of Vfcin Americana, Muhl. 



This species is quite distinct, both in its spores and in the size and character of the 

 peridia, from M. album, Clinton, which also inhabits Vicia Americana. 



zEcidium: ABUNDANS, Pk. — Spots yellow, numerous, small, sub-orbicular, sometimes 

 confluent; peridia few, liypophyllous, sub-circinating, pustulate; spores sub-globose, 

 orange, .001 inch in diameter; spermogonia on both sides of the leaf on the same or on 

 different spots. 



Living leaves of Symphoricarpus oreophilus. 



The leaves of the host plant are beautifully mottled by the spots. The peridia in 

 the specimens seen are nearly all closed, from which it is probable that they are scarcely 

 mature. 



vEcidium Bigei.oyi.e, Pk. — Spots thickened, yellow ; peridia pustulate, hemispher- 

 ical, opening by a small aperture; spores sub-globose, bright yellow or orange, .001-.0013 

 inch in diameter. 



Living steins and leaves of Bigelovia Douglasii, Gray. 



The peridia resemble those of vA\ hemispharricum, but the species is at once distin- 

 guished by the yellow spots and larger spores. 



Uromvcks iivai.ixks, Pk. — Spots none; sori numerous, liypophyllous, at first cov- 

 ered by the hyaline membranous epidermis, at length exposed, effused, nearly or quite
