hemlock, Abies Canadensis. Catskill mountains. Aug. This Poly- 

 porns is apparently related to P. destructor. It is often entirely 

 resupinate. The pileus is narrow, scarcely exceeding half an inch in 

 breadth, but it is frequently two or three inches long. It is generally 

 distinctly wavy or almost complicate after the manner of Stereum 

 complication. 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, n. sp. Suborbicular, narrowly reflexed 

 above, subvillose, whitish or , alutaceous; pores short, minute, 

 rotund, white, with thiu acute dissepiments. Bark of dead maple, 

 Acer spicatum. (Jatskill mountains. Aug. Related to P. semisupinus, 

 B. & (J. 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, G. & 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.

Tremella epiggea, 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, n. 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 .0002 in. 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, n. 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; sporeslarge, 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. puniceus which it closely resembles. When 

 viewed with a glass of high power the spores appear minutely rough.
