cylindrical, or oblong-clavate, -003'— -0045' long, about -00032' 

 broad ; spores filiform, variously curved, sometimes multinucleate, 



• 0016' — 003' long. 



Dead stems and branches of mountain holly, Nemopanthes 

 Canadensis. Grafton, Rensselaer county. July. 



The tufts are erumpent and quite prominent. They vary much 

 in size, but are generally one to two lines broad. The receptacles 

 are so closely crowded that the disk is often angular from mutual 

 pressure. The species is similar in its appearance to Tympanis 

 alnea. 

 Oenangium betulixum, n. sp. 



Receptacles casspitose or subseriate, erumpent through short 

 transverse chinks in the bark, at first sphseriiform, then open, 

 black, the disk nearly plane, slightly margined, often irregular 

 from mutual pressure, -007' — 014' broad; asci oblong or sub- 

 clavate, -0016' long, about -0004' broad ; spores crowded, oblong, 

 obtuse, slightly colored, triseptate, -0004' — 0005' long, about 



• 00016' broad. 



Dead bark of white birch, Betula popuUfolia. Center. May. 



This species differs from C. seriatum, which also occurs on 

 birch, in its small size, smaller tufts, which usually contain five 

 to ten plants, and in its septate spores. 



TrIBLIDIUM CLAV2ESPORUM, U. Sp* 



Receptacles, when moist, suborbicular, plane or slightly convex, 

 margined, -03' — 04' broad, black, when dry more or less con- 

 tracted, hysteriiform, with thick labiae; asci clavate or cylindrical, 

 •0035' — 0045' long ; spares oblong-clavate, crowded or biseriate, 

 colored, four-septate, -0009' — 0011' long, -0003' — 0004' broad. 



Decorticated wood of willows, Salix nigra. Albany. July. 

 Ascomtces deformans, Berk. 



Living leaves of peach trees. Sandlake. 

 Gymnascella, gen. nov. 



Perithecia wanting ; asci numerous, subglobose, produced upon 

 or among slender, branching filaments. 



Externally this fungus has the aspect of species of Sporotrichum, 

 but the spores are produced in asci. 

 Gtmnascella auraxtiaca, n. sp. 



Filaments slender, branched, intricate, colored, forming minute 

 subconfluent bright-orange or scarlet-colored tufts; asci numerous, 

 subglobose, produced among the filaments, -0004' — 0006' long ; 

 spores orbicular, -00016'— -0002' broad, crowded in the ascus, 

 colorless, generally uninucleate.
