Helminthosporium septemseptatum, Ph. Cut surface of maple 

 stump. Helderberg mountains. Nov. The young spores are color- 

 less, adhere firmly to the tips of the flocci and are either simple or one 

 to three-septate. When mature they are colored, easily separated from 

 the flocci and six or seven-septate. The species is allied to H.fusis- 

 porum, but in that the spores are described as narrower than the flocci, 

 in our plant they are broader than the flocci. 



Helminthosporium inconspicuum, C. & E. Living or languishing 

 leaves of Indian corn. Sand lake and Albany. July and Sept. 



Helminthosporium arbusculoides, n. sp. Flocci rather slender, long, 

 simple, subflexuous, often decumbent at the base, multiseptate, opaque, 

 black,- forming extensive blackish patches ; spores terminal, oblong or 

 narrowly elliptical, colored, triseptate, .00065 in. to .00085 in. long, 

 about .0003 in. broad, the terminal cells sometimes paler. Bark of 

 living white birch, Betula populi folia. West Albany. Oct. The 

 species is apparently allied to H. arbuscula, from which it is distin- 

 quished especially by its septate flocci. The articulations are numer- 

 ous, being once or twice as long as broad, but owing to the opaque 

 character of the flocci the septa are not always distinctly seen. The 

 decumbent flocci present a very straggling appearance. They form ex- 

 tensive patches which sometimes entirely surround the trunks of small 

 trees, especially near the base. 



Zygodesmus bicolor, C. & E. Decaying leaves and fungi. Helder- 

 berg mountains. Nov. The margin is sometimes nearly uniformly 

 colored with the rest of the stratum. 



Khinotrichum subalutaceum, n. sp. Flocci elongated, branched, 

 creeping, intricate, septate, forming brovvnish-alutaceous tomentose 

 patches, fertile branches commonly short, narrowed and minutely 

 roughened with spicules at the apex; spores globose, colored, minutely 

 roughened or echinulate, .0003 in. to .0004 in. in diameter. Decaying 

 wood. Helderberg mountains. Nov. The fertile branches are 

 generally short and without septa. They are usually abruptly narrowed 

 at the apex and there rough with minute spicules on which the globose 

 spores are borne. 



Zasmidium cellare, Pers. Decaying wood in damp shaded places. 

 Ithaca. Prentiss. The specimens are without fruit but apparently 

 belong here. 



Peziza (Humaria) hydrophila, n. sp. Oups scattered, sessile, 

 expanded, nearly plane or even convex, reddish-brown when moist, 

 black when dry. two to four lines broad; asci cylindrical; spores 

 uniseriate, elliptical, generally binucleate, ,0009 in. to .001 in. long, 

 .0000 in.' to .0007 in. broad, paraphyses numerous, thickened above, 

 brown, closely compacted and adhering to each other. Decaying wood 

 lying in water. Adirondack mountains. July. Externally this 

 fungus has the general appearance of some species of Bulgaria, but its 

 softer fleshy substance requires its reference to the genus Peziza. The 

 numerous colored coalescing paraphyses constitute a distinctive feature. 



Peziza atrata, Fr. Dead stems of herbs. Albany. May. 



Peziza fnsarioides. Berk. Dead stems of nettles. Albany. June. 



Peziza aurelia, Pers. Decaying wood. Ithaca. Prentiss.
