Cribraria 199 



generally, is that C. microcarpa represents a form somewhat like 

 C. tenella, but smaller in size, on long stalks, without a cup, more 

 or less rounded, thickened nodes, and ochraceous in color with 

 ochraceous spores. Schrader's description seems to bear this out.

Dictydium splendens Schrad. Nov. Gen. PI. 14. 1797. 



Plasmodium lead-colored (Lister). Sporangia scattered, glo- 

 bose, flattened beneath, stalked, erect or inclined, 0.3 to 0.6 mm. 

 diam., pale yellow, or brown after the spores are discharged; 

 sporangial wall consisting in the lower part of nine or more free 

 ribs with little trace of a persistent cup, the ribs continued into a 

 loose net with rather small meshes except between the ribs, and 

 with small, flattened nodes which may be poorly developed; 

 plasmodic granules minute and inconspicuous. Stalk slender, 

 brown, three to five times the height of the sporangium. Spores 

 yellow in mass, much paler by transmitted light, nearly smooth, 

 5-7 ju diam. 



Type locality: Germany. 



Habitat: On dead coniferous wood. 



Distribution: *Iowa, Maine, New Hampshire, New York, 

 *Nova Scotia, *Ontario, Pennsylvania, Tennessee, *Washington, 

 *West Indies, *Wyoming.

This species is rare. We have found it on four occasions, and 

 each time on very rotten wood in wet places. The developments 

 are small, and appear in the field like poor phases of C. intricata 

 var. dictydioides , because of the pale color and frequent collapse 

 of the net due to the large spaces between the ribs in the lower part 

 of the sporangium. The ribs constitute the important character. 

 Occasionally, the nodes of the net approach those of C. aurantiaca, 

 C. intricata, or C. tenella.

Plasmodium? Sporangia crowded on a membranous hypo- 

 thallus, stalked, subglobose, contracted at the base, brick-orange 

 to red, 0.8 to 1.5 mm. diam.; sporangial wall forming a weak, 

 shallow cup with dark ribs merging above into the net, the nodes
