Specimens from America from low elevations have usually more 
numerous and delicate connecting threads, and more prominent nodes in 
the upper part of the net ; they approach forms of C. inMcata, while 
the European type is coarser and more nearly resembles bold forms 
of C. aurantiaca. A gathering made by Dr. Rex at an elevation of 
6,200 feet on Roan Mount, N. Carolina, exactly corresponds with 
Rostafinski's type in the Strassburg collection..

Sporangia solitary ; stalk 1-5 to 2-5 mm. high, furrowed, thick below, 
narrowed upward ; sporangia globose, brown, 0 8 to 1 mm, broad ; 
cup one- third the height of the sporangium, bright brown, with 
net-like granular thickenings on the inner side as in C. argillacea ; 
net dense with thickened nodes 3 to 4 angled, with concave sides, 
united with one another by thin connecting strands ; the upper edge 
of the cup toothed, the teeth running into long linear parallel ribs 
as in Dictydium, which are bound together by thin horizontal threads ; 
the ribs are 30 to 40 in a sporangium, and lose themselves at 
the summit in a Crib7-aria-like net with 3 to 6 angled concave -sided 
knots and ray-like connecting threads ; spores bright yellow, smooth, 
6 to 7 mm. diam.

6. C. aurantiaca Schrad., Nov. Gen. PL, p. 5 (1797). Plas- 
modium sap-green. Total height 1 to 2 mm. Sporangia globose, 
gregarious, stipitate, erect or nodding, 0"4 to 0*7 mm. diam., 
nut-brown ; cup one-third the height of the sporangium, 
irregiilarly and deeply toothed at the margin, beset with round 
plasmodic granules 0"5 to 1 [l diam., arranged in close Knes 
radiating from the base of the sporangium ; nodes of the net 
flattened, broad, or narrow, branching, angular, the angles 
continued into the delicate connecting threads, and often into 
a few free rays. Stalk subulate, dark brown, two to four times 
the height of the sporangium. Spores golden-yellow or ochraceous, 
smooth, 5 to 6 /A diam. — Rost., Mon., p. 233 ; Cooke, Myx. Brit.,
