Russula pectinata, Fr. 



Grassy or mossy ground in thiii woods or groves. Menands and 

 Cemetery, Albany county. July. 



Marasmius fcBtidus, Fr. 



On fallen twigs, leaves, etc. Manor. September. In our j^lant 

 the pileus is rufescent. The stem also is rufescent above, brown 

 below. The species is easily known by its strong odor. 



Marasmius albiceps, n. sp. 



[Plate 2. Pigs. 15 to 18.] 



Pileus membranous, either convex or campanulate, glabrous, white; 

 lamellae broad, distant, adnate or arcuate-dec urrent, white; stem 

 corneous, setiform, glabrous, black, paler at the apex, attached to the 

 matrix by radiating brown hairs or fibres; spores obovate or subel- 

 liptical, .00025 to 0008 in. long, about halt as broad, usually contain- 

 ing a shining nucleus. 



Pileus about 2 lines broad; stem 8 to 15 lines long. 



Among fallen leaves in mixed woods. Manor. September. In 

 shape the pileus often approaches that of Omphalia fibula. In the 

 larger specimens the lamellse are strongly decurrent as in that species. 



Polyporus caesarius, Fr. 



The specimens which I have referred to this species have a striking 

 resemblance to faded specimens of Polyporus sulphureus, but in addi- 

 tion to the paler pileus the pores are white and more unequal. The 

 spores, also, are smaller than those of P. sulphureus, though I can not 

 tell if thjy agree with the spores of the European P. cwsarius, for I 

 have been able to find no description which gives their dimensions. 

 Our specimens were found at the base of an oak stump, near Manor. 

 September. 



Polyporus hispidus, Fr. 



Oak trunk. Quogue. September. But a single, rather old speci- 

 men was found. It is evi leutly a rare species with us, though said 

 to be more plentiful farther south. 



Poria late-marginata, D. & M. 

 Prostrate trunk of wild red cherry, PrwriMS Pennsylvanica. South 

 Ballston. 



Poria aurea, n. sp. 



Effused, forming patches several inches in extent, 2 to 3 lines thick, 

 separable from the matrix, golden yellow; subiculum thin, sub-gelatin-
