Srar—e Musrum or Narurat Husrory. 51, 
Helminthosporium septemseptatum, Px. 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. @ #, Wiving or languishing 
leaves of Indian corn. Sandlake and Albany. July and Sept. 
Helminthosporium arbusculoides, 2. 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 populifolia. 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 Jong 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. & #. Decaying leaves and fungi. Helder- 
berg mountains. Noy. The margin is sometimes nearly uniformly 
colored with the rest of the stratum. 
Rhinotrichum subalutaceum, ». sp. Flocci elongated, branched, 
creeping, intricate, septate, forming brownish-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, ~. sp. Cups 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, 
.0006 in. to .0007 in. broad, paraphyses numerous, thickened above, 
brown, closely compacted and adhering toeach 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.
