— 4i !J, the upper end rounded and obtuse, the lower end subacute. The 

 hairs which remain as a fringe around the margin of tlie tuberculiform 

 hymenium are without septa, unihilate or crisped and about in diam- 

 eter. This varies considerably from the usual type of Patellaria. 



Yentukia GAULTiiEHi.i:. E. & E. — On living leaves of GauJtheria 

 procunihens, Newheld, X. J.. July. On orbicular, dark brown, i mm. 

 spots whicli are most'y of a lighter color (gray) in the center. Perithecia 

 scattered, orbicular (75 ."■), membranaceous and rather coarsely cellular, 

 witn a few. black, continuous, straight, spreading, 3-5 x 3 ,"- bristles above. 

 Asci ovate-oblong, 80— 8o x8— 11 broader and slightly curved below, 

 sessile, without paraphyses. Sporidia biseriate, subhyaline (with a green- 

 ish yellow tint), ovate-oblong, 3—4 nucleate, 1-septate and slightly con- 

 stricted at the septum, 11—14 x 3 p-. 



Phyllosticta Gaultheri^, E. & E.— On living leaves of Gaul- 

 theria '.irocinnbois. Xewtield, X. J., July, 1885. Spots amphigenous, scat- 

 tered, dark reddish-purple, small (1— 2"mm.), with a still darker purplish 

 border. Perithecia amphigenous, sublenticular, black, coarsely cellular, 

 slightly prominent, covered by the cuticle, 100—115 /J-. Spores elliptical, 

 hyaline, granular, 5 — 7 x 4 — 5 Z^-. 



Ch.etomella (?) PERFORATA, E. & E. — Perithecia superficial, sub- 

 giobose (i — i mm.) with a small, circular opening above, sparingly 

 clothed with straight, black, continuous, bristle-like hairs about equal in 

 length to the diameter of the perithecia, more thickly set around the ori- 

 fice, paler and more or less substellate-tuf ted below ; spores very variable, 

 from short oblong to oblong-elliptical, 10 p- long and uniseptate to 30 p 

 long and 3-septate, about 4 ,'J- wide, constricted at the septa and having 

 in the mass a rosy hue. Differs from the type of CTmtomella in its per- 

 forated perithecium and septate spores. On Cirsiiim discolor, Charles 

 City, Iowa, Sept., '82, Prof. J. C. Arthur, and on Cirsimn altissimum, and 

 Artemisia Ludoviciana, Ames, Iowa, Prof. C. E. Bessey. 



STILBU3I ACTCULOSTJM, E. & E.— On decaying leaves of Orontium 

 aquatAcum, Xewfield, N. J., July 22d, 1885. Acicular, white, stem some- 

 what swollen towards the base, and about 40 p thick, gradually taper- 

 ing above to 12 or 15 p thick, f — 1 mm. high, composed of hyaline, com- 

 pacted fibers, of which the free ends of some project like bristles along 

 the sides of the stem. Head obovate, about 75 p high and 60—75 fJ- 

 thick, spores oblong-elliptical, hyaline, 5 — 6 x H /^-, borne in a dense stra- 

 tum at the ends of the hyphse. 



Stilbum corynoides, E. & E.— On Hypoxylon tinctor, Berk, Louis- 

 iana, A. B. Langlais. 29, com. Prof. F. L. Scribner. Stem slender, flex- 

 ible, black but covered with a glaucous bloom, of fibrous texture, finely 

 divided above and spreading' into the close, spherical, fiesh-colored head 

 (i — i mm.) which is formed of the conglutinated, oblong-oval or elliptical 

 4—5 x 2i [J- spores. The fungus does not grow directly from the Hypoxy- 

 lon but springs from under the margin of bark and lichens surrounding it. 



STILBU3I ECHiNATUM, E. & E. — Parasitic on Arcyria cinerea, Adiron- 

 dack Mts., X. Y., Aug. 1884 and 1885. Coll. by Dr. Geo. A. Kex. Pro- 

 jecting horizontally (for the most part) from decaying heads of the 

 Arcyria and thus causing them to appear echinate. White throughout ; 

 stem 300—350 x 30—40 p, straight ; head globose, 100—115 P diameter. 

 Snores globose, minute (i />-). 8. tommtosum, Schrad., is a much coarser 

 plant with oblong spores 4—5 x li

Perithecia immersed, membranaceous, ostiolate ; stjdospores cylin- 

 drical, large, septate, stipitate. Genus dedicated to Dr. W. A, Keller- 

 man, its discoverer.
