hemlock, Abies Canadensis. Catskill mountains. Aug. This Poly- 
porus is apparently related to P. destructor. It is often entirely 
resupinate. ‘The pileus is narrow, scarcely exceeding half an inch in 
bréadth, but it is frequently two or three inches long. It is generally 
distinctly wavy or almost complicate after the manner of Sterewm 
complicatum. The substance is soft when fresh but becomes hard in 
drying. The pores are much longer than the thickness of the pileus 
which is at first slightly fibrillose-tomentose. 
Polyporus semipileatus, 2. sp.  Suborbicular, narrowly reflexed 
above, subvillose, whitish or alutaceous; pores short, minute, 
rotund, white, with thin acute dissepiments. Bark of dead maple, 
Acer spicatum. Catskill mountains. Aug. Related to P. semisupinus, 
B.& C. The effused or resupinate part of the fungus is usually about 
one inch in diameter. ‘The pileus or reflexed part is scarcely half an 
inch broad. The pores are so minute that they are scarcely visible to 
the naked eye. Both this and the preceding species belong to the 
section Anodermei. 
Irpex viticola, C. @ P. n. sp. Resupinate, suborbicular or con- 
fluent in long patches, the margin usually definite and slightly reflexed, 
subcinereous ; teeth compressed, subincised, acute or obtuse, whitish 
or pallid. Dead grape vines. North Greenbush. July. 
Grandinia crustosa, Fr. Decaying wood and bark. Helderberg 
mountains. Novy. 
Pterula densissima, B. & C. Decaying wood. Helderberg moun- 
tains. Nov. 
Tremella epigea, B. @ Br. Catskill mountains. The habitat of this 
species is the ground, but our specimens were growing on the hymenium 
of and old Polyporus near the ground. 
Tremella subochracea, 7. sp. Small, two to four lines in diameter, 
forming interrupted or anastomosing lines or patches, gyrose-plicate, 
pale-ochraceous, becoming darker in drying ; spores oblong or oblong- 
pyriform, slightly curved at the small end, colorless, .0004 in. to. .0005 
in. long, .00016 in. to .0002in. broad. Decorticated wood of poplar, 
Populus monilifera. Albany. Sept. A peculiar feature of this 
species is its tendency to grow in lines which run together in a reticu- 
late manner. ‘The color is a dingy-yellow or subochraceous.

Arcyria macrospora, 7. sp. Sporangia short, oval or ovate-oblong, 
crowded, stipitate, the persistent basal part smooth or finely striate; 
stem short, reddish-brown or chestnut color; capillitium and mass of 
spores red, the filaments .0002 in. to .0003 in. thick, rough with 
numerous spines and spiny bands; spores large, globose, nearly smooth, 
.0004 in. to .0005 in. in diameter. Decaying wood. Ithaca. Prentiss. 
Copake. Oct. The large size of the spores in this fungus induces me 
to separate it from A. puwnicews which it closely resembles. When 
viewed with a glass of high power the spores appear minutely rough.
