very thin threads connecting large, brown, irregularly stellate

On decayed pine-wood and on sphagnum. Britain (Cleve- 

 don, Bristol) ; Germany ; Sweden ; Finland ; United States. 



Gregarious, 2'5 3 mm. high. Distinguished amongst species 

 without a calyculus by the small sporangium and elongated 

 stem ; also by the elongated, flattened, radiating ribs at the 

 base of the network, thus approaching the type of structure 

 on which Rostafinski's genus Heterodictyon was founded. 



Cribraria splendens, Rost. 



Sporangia globose, stipitate, erect, yellowish, calyculus not 

 differentiated, membrane between the thickened portions for a long 

 time persistent ; nodes large, angular-, containing granules ; stem 

 elongated, slender, sometimes flexuous, purple-brown; spores 

 pale yellow, globose, smooth, 5 7 p. diameter.

On rotten pine-wood. Germany ; Finland ; Sweden ; Switzer- 

 land. 



Scattered, about 2 mm. high, stem about three times as long 

 as sporangium. Distinguished by the very persistent nature 

 of the membrane between the thickened portions.
