Polyporus pineus, /;. sjj. 



Resupiuate, irregular from the inequalities of the matrix, rather 

 tender but separable from the matrix, the thin subiculum and margin 

 whitish, sometimes tinged with yellow; "pores rather large, angular, 

 unequal, two to three lines long, often oblique and lacerated, dingy 

 whitish, becoming blackish where bruised or wounded, the whole 

 plant becoming blackish or blackish-brown in drying. 



Wood and bark of pine. Selkirk. August. 



The species is apparently allied to P. (Miquus, but the pores can not 

 be described as very small, nor has our plant an " erect crested 

 margin." It has a distict subiculum on which the pores are formed 

 and by reason of which the jDlant is separable from the matrix. 



Merulius Ravenelii, Berk. 



Bark of prostrate trunks of sjDruce, Abies nigra. Adirondack moun- 

 tains. July to September. 



This fungus varies in hue from flesh color to dark smoky red or 

 brownish-red. The pores are at first shallow with obtuse folds or 

 dissei^iments, but with age these become thinner and the pores deeper 

 so that the plant might easily be taken for a Polyporus. Its pure 

 white margin contrasts conspicuously with its dark waxy hymeniiim. 

 The specimens labeled Merulius serpens in Ravenel's Exsiccati, Vol. 

 IV, 9, belong to this species. 



Merulius himantioides, Fr: 



Prostrate trunks of hemlock. Catskill mountains. September. 



The color of the hymenium resembles that of JI. lacnjmans, but the 

 subiculum is very different. The fungus is soft, tender and mem- 

 branous, and by confluence becomes widely effused. The subiculum 

 is sometimes studded with drops of a reddish color, and is composed 

 in part of branching strings of mycelium. • ,^ 



Hydnum fasciatum, n. sjx 



Pileus thin, coriaceous, nearly plane, umbilicate, blackish-brown, 



' adorned with three to seven narrow elevated scabrous, tawny-gray 



concentric zones; aculei short, decurrent, ferruginous-brown; stem 



short, slender, tough, tawny-gray or blackish; spores subglobose, 



rough, .00016 in. broad. 



Pileus 6 to 12 lines broad; stem 4 to 6 lines long. 



Naked ground in woods. Catskill mountains. September. 



The specimens were past maturity when collected, and the colors of 

 young plants may vary somewhat from those here given. The species
