This species is well distinguished by its very slender form and 

 the great length of its spores and sporophores. In one or two of the 

 tufts it seems possible to distinguish the body of the spores, from 

 the middle segments of which they seem to have arisen, lying flat 

 against the substratum. 



Muiara Lonchaeana, nov. sp. — Plate XVII, figs, io-ii 



Scaly-punctate throughout, or almost hirsute. Sterile and 

 fertile elements relatively rather short and stout, densely crowded; 

 the sterile elements numerous. Basal cell of the spore usually 

 rather abruptly distinguished from the sporophore, which is often 

 shorter than the spore itself; the body of which is irregular, its 

 basal and distal cells variably inflated and constricted at the septa, 

 rarely divided longitudinally. Spores 100-140X15-18 \x, the stalk 



35-7oX8 m. 



On the abdomen, legs, and antennae of Lonchaea sp., no. 2298, Kamerun, 

 West Africa (Schwab). 



This species is characterized by its dense habit of growth, dark 

 color, conspicuously and coarsely scaly-punctate spores, which 

 are more irregular in outline than those of the other species, and 

 are borne on relatively short stalks. The sterile elements are more 

 than usually numerous and are roughened much like the spores. 

 In certain instances small groups have been observed which seem 

 certainly not to have sprung from entire spores, but rather from 

 small fragments. Two specimens of the host were found to be 



parasitized.
