Sporangia scattered, very minute, .25-35 mm., spherical, long- 

 stipitate, drooping; stipe 2.5-3 mm., slender, flexuous, subulate, rugu- 

 lose ; calyculus about one-third the sporangium, reddish brown, shin- 

 ing, minutely striate with granular lines, the margin more or less 

 regularly serrate; net reddish brown, the meshes triangular and the 

 threads simple, the nodes large, polygonal, flat, but well differen- 

 tiated ; the spores when fresh dull red in mass, paling with age ; by 

 transmitted light colorless, 6 /x, smooth. 



A very singular species, easily recognizable by its long, slender 

 stipes, terminating in exceedingly small spherical sporangia. The 

 colors are obscure, but the striations on the calyculus are violet- 

 tinted, and the reds perhaps predominate elsewhere. "In its scattered 

 and solitary growth, its tall, slender stipes, and relaxed habit it re- 

 sembles C. microcarpa, in its network it approaches C. tenella, and its 

 spores have the color of the paler form of C. purpurea." So Dr. Rex, 

 /. c. Western forms of the first-named species have much shorter 

 stipes; the network in the specimens before us is unlike that of C. 

 tenella, but resembles that of C. purpurea. 



Rare, on very rotten wood, in the forest. New York, Ohio, South 

 Carolina, Ontario. 



16. Cribraria cuprea Morgan. 



Plate XVII., Fig. 7. 



1893. Cribraria cuprea Morg., Jour. Cin. Soc, p. 16. 



Sporangium very small, .33 mm., oval or somewhat obvoid, copper- 

 colored, stipitate, nodding; stipe concolorous or darker below, subu- 

 late, curved at the apex, 2-4 times the sporangium; calyculus about 

 one-half the sporangium, finely ribbed and granulose within, the 

 margin nearly even ; the net rather rudimentary, the meshes large, 

 triangular or quadrilateral, the nodules also large, flat, concolorous, 

 the threads slender, transparent, with free ends few; spores in mass 

 copper-colored, by transmitted light colorless, smooth, 6-7 /*.
