80 Forty-fifth Report on the State Museum. 



The pileus is at first covered with a fawn-colored or tawny- 

 brown tomentum which soon breaks up and forms scales. The 

 flesh is white and the lamellae are at first whitish, soon flesh- 

 colored, then brown. The spores are brown, elliptical, .0002 to 

 .00025 in. long, .00016 broad. 



Hypholoma subaquilum Banning. 



Decaying wood. Adirondack mountains. August and 

 September. 



This species is closely allied to H. appendiculatum, but may be 

 separated by its darker color, and especially by the darker color 

 of its lamellae. 



Russula roseipes Bres. 



Under hemlock trees. Menands. August. It might easily be 

 taken for a small form of R. alutacea, from which its more 

 strongly striate-tuberculate margin distinguishes it. It is edible. 



Daedalea quercina Fr. 



Dead stumps and trunks of oak. Selkirk, Albany county. 



August. 



Septoria podophyllina Ph. 



Living and languishing leaves of mandrake, Podophyllum 

 peltatum. Freeville. July. 



Glceosporium nervisequum Sacc. 



Living leaves of sycamore, Platanus occidentalis. McLean, 

 Tompkins county. July. 



This fungus attacks the foliage and young branches early in 

 the season and is often quite injurious to the tree. It manifests 

 its presence either by discolored spots which follow the principal 

 veins of the leaf, or by producing broad and irregular brown 

 patches in the leaf. When the attack is severe it kills the entire 

 leaf or even the branch and all its leaves. Indeed, it is said 

 sometimes to be fatal to the tree. 



Glceosporium populinum n. sp. 



Spots small, 1 to 2 lines broad, nearly orbicular, reddish-brown, 

 often paler in the center and then appearing to be surrounded by 

 a broad darker margin, paler on the lower surface ; heaps of 

 spores hypophyllous, either single jind central or several more or
