TROPOSPOEIUM, Hk. 



Sporodochium flattened, farinaceous. Hyphse elongated, lax, branch- 

 ing. Spores spiral, attached to the hyphse by slender, pedicel-like branch- 

 lets. Allied to Fusisporium, but with very different spores. 



Troposporium albtjm, Hk. 



Acervuli white, 1—2 mm., often confluent, thick, branching freely, 

 without septa, containing numerous granules and oil globules which are 

 set free by breaking ; spore— a long tube, granular, nucleolate, without 

 septa, 7 wide, coiled in a long spiral of 3—7 turns, flattened at the cross- 

 ings, forming an oblong mass, with crenate borders 40—45 x 12—22 P-. 



On dead stems of Corylus rostrata. December. 



THECLOSPORA, Hk. 



Spores surrounded by a cleft, hyaline border, borne on slender, 

 branching hyphse, compacted into a globular, woody mass. 



Theclospora bifida, Hk. 



H^aps scattered, globular, 1—2 mm. in diameter, loosely attached to 

 the surface, white, becoming yellow ; hyphse arising from irregular, yel- 

 lowish, elongated masses, rough, slender, bearing at intervals granular 

 spores, surrounded by a broad and firm hyaline or yellowish border, 

 marked with concentric striae, and cleft on opposite sides, the hypha 

 apparently passing through, 24—40 



On rotting leaves of Eucalyptus globulus, December. 



The place of this fungus in classification is very uncertain, and it is 

 only placed here because of its connection with the next. 



CLEISTOSOMA, Hk. 



Perithecia orbicular, membraneous. Asci borne on branching 

 threads, globose, evanescent. Sporidia hemispherical, echinulate. 



Cleistoso^ia purpureijm. Hk. 



Perithecia purple black, very delicate, soon dehiscent, developed 

 within the heaps of Cleistosoma purpureum, which it stains purple ; asci 

 globular, hyaline, 8— spored, 9—12 p- ; sporidia purple, hemispherical, 

 long echinulate around the disk margin, 3 — 4 ij-. 



BuRRiLL, T. J. "New Species of Uredinese ;" in Botanical Gazette, 

 Dec. 1884. 



The species described are from large collections of Illinois fungi 

 made mostly by Mr. A. B. Seymour for the State Laboratory of ^N'atural 

 History. Mr. Seymour is author of the last three species named in the 

 list ; Uromyces (Enotherse, Burrill, I, II, and III, on (E. linif olia ; 

 Uromyces Scirpi, Burrill, II and HI, on S. fluviatilis ; Uromyces gramin- 

 icola, Burrill, on Panicum virgatum and Elymus Virginicus ; Puccinia 

 tenuis, Burrill, I (^cidium tenue, Schw.) and III, on leaves of Eupato- 

 rium ageratoides ; Puccinia Seymerise, Burrill, III. on S. macrophylla ; 

 Melampsora Crotonis (Cooke), II and III, (Trichobasis Crotonis, Cooke) 

 on leaves of Croton capitatum, C. mononthogynus, and Crotonopsis line-
