Sph^eria (Seriate) maydis, d. sp. — On dead culms of Zea Mays. 

 Cincinnati, May 1, 1841. 



Masculis parvis, subellipticis, elevatis; peritheciis paucis, ostiolo, 

 unico, conico; sporidiis oblongiis, curvulis, uniseptatis. 



Habit that of S. arundinacea. Spots minute, often purple-brown, 

 punctiform or subelliptic, rarely linear, containing very few perithecia, 

 with a single broad conical ostiolum; sporidia oblong, slightly curved, 

 uniseptate. Very different from Sphceria Zeoe, Schwein., as appears from 

 an authentic specimen in Sir W. J. Hooker's Herbarium. 



Sph^eria (Byssised^e) rhodomphala, Berk. — On rotten wood. Cin- 

 cinnati, Dec. 9, 1841. 



Peritheciis demum confertis, minutis globosis umbilicatis, atris, 

 plus minus, prsesertim circa ostiolum, obsoletum, miniato-pruinatis, 

 sub Iente scabriusculis subiculio fusco insidentibus. — Berk, in Hook. 

 Lond. Journ., vol. iv., p. 313. 



Scattered, at length much crowded, either free or seated on a 

 matted brown subiculum; perithecia globose, at first powdered with 

 vermilion, which is more or less persistent in the center; ostiolum 

 simple, umbilicate; asci somewhat lanceolate, pedicellate; sporidia 

 lanceolate, constricted in the center with a single septum, and containing 

 one or sometimes two nuclei. A pretty species, but rather diffi- 

 cult to place, as the subiculum is sometimes entirel}* wanting, and the 

 perithecia are rather pulverulent than villous. It has almost equal 

 claims to take its place amongst Denudatce, Villosce, and Byssisedcu. 



Sph-eria (Subtect^:) argyrostigma, n. sp. — On dead leaves of Yucca 

 filamentosa. Cincinnati, Feb. 8, 1812. 



Epiphylla, ethypophylla, late dispersa; peritheciis minoribus cle- 

 presso-globosis, epidermis tectis astomio; maculis epidermalibus, 

 punctiformibus, nigris, centro, candidis; sporidiis cymbiformibus, 

 pallidis. Appearing like scattered Phoma, but it has distinct asci. 



Antennaria pixophila, Nees. — On sugar maple. Cincinnati, April 

 30, 1812.* 



OMISSION. 



Agaricus vaginatus, Bull. — Cincinnati. 



A distinct form, if not species, occurred in Banklick woods, Ohio, 

 at the root of a beech tree, growing in a bunch, with the gills attached 

 to the stem, but easil}* breaking away. The pileus was viscid, brownish 

 yellow; the stem also brownish and viscid, especially within. 



• I can not distinguish the specimens from Xees von Esenbeck's species.
