substance of the cups is of a vinous purple color under the microscope. 

 On old logs and stumps, White xMts., N. H., Sept. 1884, Miss S. Minns. 



DiATRYPE MINIMA, E. & E.— Stroma cortical, formed of the scarcely 

 iiltered substance of the bark, elliptical, 1—2 mm. in diameter, limited 

 by a black circumscribing line which penetrates the wood beneath. Per- 

 iiheci.i 8— 12 in a stroma, lying in a single layer, globose (1-6—1-5 mm.) 

 membranaceous with black, rather thick walls and short, obtuse osiiola, 

 their apices papilliform, black and shining at first, then distinctly per- 

 forated with a rather broad opening. Asci cylindrical, 70—80 x 2i— 3 />- 

 Paraphyses obscure (or none ?) Sporidia uniseriate, lying end to end^ 

 oblong-elliptical, 2-nucIeate, yellowish, nearly hyaline, 5—7 x 2 /^-. The 

 black, scarcely projecting ostiola which dot the small tuberculiform 

 stroma are visible through short, longitudinal cracks or chinks in the 

 slightly elevated epidermis. On dead shoots and limbs of Magnolia 

 glauca, JSTewfield, N. J., April, 1885. First noticed in December, 1881. 

 Probably not uncommon but easily overlooked. 



Leptosph^ria IIarknessiana, E. & E.— Perithecia scattered or 

 gregarious, at first covered by the epidermis, at length bare and superfi- 

 cial or nearly so, hemispherical, black, smooth, i— i mm. in diameter. 

 Ostiolum short, cylindrical, with a large, circular opening. Asci cylin- 

 drical, 100 114 X 10 — 12 8-spored and surrounded with filiform para- 

 physes. Sporidia in a single series, lying end to end, elliptical, yellow- 

 brown, 3-septate and constricted at the septa, 18—22 x 7—9 obtusely 

 pointed above and regularly rounded below. The perithecia are much 

 like tliose of Sphceria subconica, C. & P., but the ostiolum is shorter. On 

 dead stems of ''Columbo" (FraseraV) Emery Co., Utah, S. J. Harkness, 

 no. 106. 



Sph^ria (Metasph^ria) cavernosa, E. & E.— Perithecia coriaceo. 

 carbonaceous, black, rather thin walled, i — I mm. in diam., sometimes 

 2—3 united, at first covered by the fibres of the bark, the upper half at 

 length projectir.g and nearly bare. Ostiolum sub tuberculiform, obtuse, 

 broad. Asci clavate-cylindrical, 80 — 115 x 12 — 15 with filiform para- 

 physes. Sporidia uniseriate or partly bi-seriate above, rather acutely 

 elliptical, endochrome 3-times divided, hyaline, 18—22 x 7—9 The 

 upper part of the perithecium at length falls away, leaving the black, 

 cup-shape d, hemispherical base bedded in the bark. Closely allied to 8. 

 leiostega, EIL, which is scarcely distinct from S. corticola, Fckl. It differs 

 however in its denuded perithecia, longer and broader asci, and rather 

 longer sporidia. The sporidia of 8. leiostega are mostly 14—18 x 7—8 

 very few reaching 20 p- long, as stated in Torr. Bull. On bark of Taxo- 

 dium distichum, Darien, Ga., H. W. Bavenel, 703. 



Speleria (Winteria) coerulea, E. & E.— Perithecia scattered, 

 membranaceous, flattened, i— i mm. in diam., covered by the thin epider- 

 mis which is either soon partially ruptured or remains closely attached to 

 the surface of the perithecia which are plainly visible through it. Ostio- 

 lum broad, papilliform, obtuse, collapsing when dry so that the perithecia
