 gular in shape, hemispherical, depressed, or curved and elongated 



1 to 3 mm. long, 1 mm. broad ; sporangium-wall shell-like, brittle, 

 clear greyish-brown ; columella strongly developed, following the 

 shape of the plasmodiocarp, bright red-brown ; capillitium of 

 slender violet threads, with scattered knot-like thickenings; 

 spores dark violet, spinulose, 11 to 14 /* diam. 



Ilah. On dead wood. — Oppeln, Silesia.

 globose, or half-ring shaped, 1 to 2 mm. long, 1 mm. broad, 

 crowded ; the outer sporangium-wall ochre-brown, opaque, break- 

 ing up irregularly, the inner delicate, colourless; columella 

 wanting; capillitium well-developed, of smooth violet threads 



2 to 3 /* diam., branching and combined into a dense net ; spores 

 dark violet, faintly warted, 9 to 1 1 /a diam.
