The 



sterile elements scanty. Total length of stalk and spore 210 

 260 /x; average length of spore to tip 120 /x; body of spore 60X 18- 

 24 /x, the termination 3.5-4 m broad. Spur from spore-tip about 

 20X4 M, that from the stalk somewhat longer. 



On the legs of Drosophila sp., no. 2178, Sarawak, Borneo. 



This very distinct form was found among material for which 

 I am greatly indebted to the kindness of Mr. J. C. Moulton, and 

 has been seen on a single specimen only of its host. It is clearly 

 distinguished by the relatively broad and evenly curved outline 

 of the body of its spores, their characteristic markings, relatively 

 slender termination, and by the peculiar spurlike processes, which 

 may arise from the latter, as well as distally from the sporophore, 

 or may be wholly absent. 



Muiaria repens, nov. sp. — Plate XVII, figs. 6-9 



Repent on the wings or growing in tufts on other parts of the 

 host; brown, concolorous. Repent form producing rather closely 

 septate, somewhat tortuous hyphae, tending to run in straight 

 lines, sparingly branched, bearing solitary spores here and there, 

 or small groups of spores along the anterior wing margins or along 

 the larger veins. The spores in both types rather short and stout; 

 the two middle tiers not transversely divided; the cells above and 

 below them similar, or hardly distinguishable, and showing several 

 longitudinal septa; the stalks somewhat shorter than the spore, 

 as a rule, and usually bearing a subterminal spurlike process. 

 Sterile elements not distinguished. Spores 60-70X15/^ those 

 on the wings somewhat smaller. Total length including stalk 



70-100 jU. 



On the wings and abdomen of Clasiopa sp., no. 2283, Kamerun, West 

 Africa (Schwab). 



This species is unlike those previously described from the fact 

 that the four tiers of small cells, usually present in the middle of 

 the spore body, are replaced by two tiers of relatively Ian r cells, 

 which are often so similar to the cells immediately above and
