42 Thirty- fir st Report on the State Museum. 



in the genus Lamproderma, for the same objection would hold there, and 

 besides that, another is found in the presence of lime granules in the stem. 

 Even when no distinct stem is present, a small whitish mass of granules can 

 generally be seen at the point of attachment. The capillitium appears to 

 originate at the base of the sporangium. The spores are larger, but less 

 rough than those of D. splendens. 



COMATRICHA iEQTJALIS Pk. 



Gregarious or loosely clustered, about three lines high, arising from a thin 

 hypothallus; sporangia cylindrical, obtuse, fugacious, wholly falling away; 

 capillitium brown or blackish-brown, forming an intricate net-work; stem 

 slender, smooth, black, penetrating the capillitium as a columella and extend- 

 ing nearly or quite to the apex, the free portion about equal in length to one- 

 half the altitude of the entire plant ; spores globose, smooth, violet-black, 

 .0003'-.00035' in diameter. 



Decaying wood. Catskill Mountains. Sept. 



In color this species is almost exactly like Stemonitis fusca, from which its 

 more lax habit, proportionally longer stem and different capillitium separate 

 it. The larger size, both of the plant itself, and of the spores, will separate 

 it from Comatricha typhina. The length of the stem and of the capillitium 

 are nearly equal, hence the specific name. 



Comatricha Friesiana Be By. 



Decaying wood. Adirondack Mountains. Aug. 

 This is a variety with the sporangia generally globose. 

 The variety oblonga was found on the Catskill Mountains. 



Comatricha pulchella Bab. 



Decaying stems of herbs. Adirondack Mountains. Aug. 



Lamproderma violaceum Ft. 



Dead stems of herbs. Catskill Mountains. Sept. 



Our specimens have a brownish capillitium and spores .0003 '-.00035' in 

 diameter, but they are probably a mere variety of the species. 



Trichia scabra R. 



Decaying wood. Griffins. Sept. 



Trichia inconspicua R. 



Bark of buttonwood, Platanus occidentalis. Bethlehem. 



Arcyria pomiformis Roth. 



Decaying wood and bark. Mechanicville. Oct. 



Lycogala flavofuscum Ehr. 



Decaying wood and stumps. Griffins and Bethlehem. Sept. and Oct. 



Oligonema brevifila Pk. 



Bright ochery -yellow throughout ; sporangia crowded, forming clusters or 

 effused patches, shining, variable in shape ; threads few, very short, cylindri- 

 cal or subfusiform, not septate ; spores globose, rough, .00045' in diameter. 



Mosses. Oneida. Warne. 



This species differs from O. flavida (Perichcena flavida Pk.) in its darker 

 color and shorter, more strongly marked threads.
