1 70 THE NORTH AMERICAN SLIME-MOULDS 



delicate, colorless, with many free ends, the nodules dark-colored, 

 numerous and somewhat prominent ; spore-mass pale purple ; 

 spores by transmitted light pale violaceous, smooth, 6-6.5 /* 



To be compared with the preceding. The small-meshed net 

 with well-defined, dark-colored nodules is distinctive, aside from 

 the fact of the much smaller sporangia. The stipe is also 

 different, more slender, smooth, and darker-colored. The 

 habitat of the two species appears to be the same. The present 

 species is much more common, ranges farther west, and is to 

 be looked for on the Pacific coast.

14. CRIBRARIA LANGUESCENS Rex. 



1891. Cribraria languescens Rex, Proc. Phil. Acad., p. 394. 



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

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

 rugulose ; calyculus about one-third the sporangium, reddish 

 brown, shining, 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 differentiated ; the spores when fresh dull red in 

 mass, paling with age ; by transmitted light colorless, 6 //., smooth. 



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

 slender stipes, terminating in exceedingly small spherical spo- 

 rangia. The colors are obscure, but the striations on the calycu- 

 lus are violet-tinted, and the reds perhaps predominate elsewhere. 

 "In its scattered and solitary growth, its tall, slender stipes, and 

 relaxed habit it resembles C. microcarpa, in its network it 

 approaches C. tcnella, and its spores have the color of the paler 

 forms of C. purpurea." So Dr. Rex, I.e. 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. pnrpnrea. 



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

 South Carolina.
