CoLOHADO Fungi, (new species.) — By Ciias. H. Peck. — The species of fuugi here 

 described wei'c collected iu Colorado by Mr. T. S. Brandegee, and forwarded to me for 

 examination by 3fr. E. »S'. Bftit, of Bethlcliem, Pennsylvania. 



SpHiEROPSis Raui, Pk. — Si)ols indefinite, brown; porithecia numerons, gregarious, 

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

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



Living leaves of Arteniinia ncopulorirm. Gray. 



Lecythea sPEcrosA, Pk. — Spots snborbicular, one to two lines in diameter, yellow ; 

 sori few, crowded, prominent, liy])()i)iiy]l()us. oiange-colored ; abortive spores elongated, 

 curved, obtuse, nearly cylindrical; spores sublogose or ellii)tical, .001-0012 inch long, 

 rough, the endochrome bright orange. 



Living leaves of Riibus delia'osm, 'J'orr. 



Tliis is probably the early or Uredo form of some si)ecies of Phragmidium which 

 sliouid be sought later in tlie season. It is distinguished from its allies by the deep 

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



..I'EoiDiUM Bkandecsei, Pk. — Peridia amphigenous, scattered or aggregated, some- 

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

 diameter. 



Living stems and leaves of Asclepiaii verUcillata, L. 



The peridia resemble those of ^E. Thalictri, but the spores and habit of the plant 

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

 and changes the aspect of the host i)lant. 



^ciDiUM HEMisPHyERicuM, Pk. — Peridia prominent, scattered or crowded, hemis- 

 pherical, opening by a small aperture; spores orange, subglobose or elliiitical, .0008-.001 

 inch long, the epispore lliick, hyaline. 



Living stems and leaves of Mulrjcdiwn pulrhcUtim, Nutt. 



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

 lower surface of which is often occui)ied by them. 



^EciDiUM PUKOSUM, 7^/,-.— Spots uoHC; cups crowded, deep-seated, broad, wide- 

 mouthed, occuiiying 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 Vlru/ Americann, Muhl. 



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

 peridia, from JS". idbum, Clinton, which also inhabits Vicia, Ameririom. 



^ciDiDM abundans, Pk. — Spots yellow, numerous, small, sub-orbicular, sometimes 

 confluent; peridia few, hypophyllous, sub-circinating, pustulate; si)ores subglobose, 

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

 ditt'erent spots. 



Living leaves of Syinpltoricaiyus oreopTtilitH. 



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

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

 mature. 



^EciDiUM BiOEi-OVi/E, P/t.— Spots tliickencd, ycllow ; peridia pustulate, hemispher- 

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

 inch in diameter. 



Living stems and leaves of Bifjeloviu D'Hiijlasii, Cray. 



The peridia reseml)le tliose of ^E. heiniHpharicum, but the species is at once distin- 

 guished by the yellow sjiots and larger spores. 



Urojiyces iiyaijncs, /'//. — Spots non(;; sori numerous, hypophyllous, at first cov- 

 ered by the hyaline nienibranous epidermis, at length exposed, ell'used, nearly or c[uite
