This species varies much in the extent to which the net of the 

 porangium-wall is developed. In the usual form the bands are dark 

 irown, -well-defined, hardly expanded at the nodes, often stouter 

 owards the base ; but in some gatherings the thickenings are faint 

 ,nd broad, and the wall of the sporangium is nearly uniform in texture, 

 a which case.it closely resembles the form /3. simplex of Lindhladia 

 Vuhulina.

 lodium?- Total height 2 mm. Sporangia ellipsoid, shortly 

 talked, crowded, erect, 1-7 mm. high, 1 mm. broad, crimson; cup 

 eaching to half the height of the sporangium, beset with minute 

 ark plasmodic granules arranged in isolated clusters towards 

 be base of the membranous wall, and in a reticulated pattern 

 pwards, the lines becoming thickened and continued into the net 

 t the somewhat perforated margin ; net of delicate, dark brown, 

 igid threads with a mesh about 1 mm. diam., without conspicuous 

 xpansions at the nodes. Stalk rugged, dark brown, 0-3 to 

 •5 mm. long, 0-2 mm. thick. Spores rufous, almost smooth,
