Hydnum scabripes n. sp. 



Pileus fleshy, firm, coavex, glabrous, pinkish-gray, the decurved 

 margin ex'.ending beyond the aculei, flesh white ; aculei whitish 

 or subcinereous, becoming ferruginous-brown, decurrent ; stem 

 stout, nearly equal, scabrous-dotted ; spores subglobose or irregu- 

 lar, somewhat nodulose, colored, .0003 in. broad. 



Pileus 4 to 5 in. broad ; stem 4 to 5 in. long, about 1 in. thick. 



Under hemlock trees, Tsuga Canadensis. Elizabeth town. 

 September. 



The prominent characters of this species are its peculiar color 

 and its scabrous or rough-dotted stem. 



Radulum molare Fr. 



Dead bark of elm, JJlmus Americana. Cooperstown Junction. 

 June. 



I have seen no description of this species which gives the spore 

 characters. In our specimens the spores are naviculoid-elliptical, 

 .0003 in. long, .00016 to .0002 broad. Sometimes the plant is 

 effuso-reflexed, in which case the upper surface of the pileus is 

 coarsely strigose or fibrous and somewhat resembles the pileus of 

 Merulius tremellosus. 



Pyrenochaeta collabens n. sp. 



Perithecia .014 to .018 in. broad, superficial, crowded or closely 

 gregarious, submembranous, subglobose, often collapsing when 

 old, the upper part sometimes falling away and leaving a cup- 

 shaped base, black, the setas few, black, mostly near the base of 

 the perithecia; spores narrowly elliptical, nearly colorless, .0003 

 to .00045 in. long, .00016 to .0002 broad. 



Bark and wood of apple tree. Alcove. October to January. 

 C. L. Shear. 



Vermicularia Hepaticae n. sp. 



Perithecia minute, .003 to .00 1 in. broad, epiphyllous, furnished 

 with black diverffing setae which sometimes have one or two 

 septa near the base; spores narrowly fusiform, slightly curved, 

 acute at each, end, .0007 to .0009 in. long, sometimes appearing 

 to be spuriously septate in the middle. 



Dead spots on leases of IFepatica acutiloha. 



Helderberg mountains. July. 



This fungus sometimes occurs in coni)>any with Protomyces 

 fuscus. It is so small that it is scarcely visible to the naked eye.
