NEW INDO-MALAYAN LABOULBENIALES. 49 



from a very stout to a somewhat slender form. The antheridia are 

 sometimes produced in considerable numbers, especially when the 

 perithecium has been destroyed or has failed to develop. In such 

 cases they arise in tufts, and are usually paired at the ends of branch- 

 lets as in M. ornatus, and as in this instance, are relatively long, with- 

 out a clearly defined neck-portion. 



Misgomyces Clivinae nov. sp. 



Long and slender, nearly hyaline, or faintly tinged Avith brownish 

 yellow. Receptacle consisting of about ten superposed cells, the basal 

 considerably elongated, the next two or three above it squarish, the 

 remainder more elongate, all filled with coarse evenly granular proto- 

 plasm. The axis of the perithecium coincident with that of the 

 receptacle, the primary appendage-portion erect, mostly free, consist- 

 ing of two or three superposed cells somewhat elongated, the basal one 

 connected with the perithecium by a small cell which is closely united 

 to it, the terminal one bearing several evanescent branchlets. Peri- 

 thecium straight, symmetrical, slightly inflated, the tip tapering to the- 

 blunt symmetrical apex. Pei'ithecia 112X42//. Total length to- 

 tip of perithecium .580 /u. Greatest width of receptacle 32 ji. Pri- 

 mary appendage portion 70 X 12 ju. 



On the margin of the elytra of Clicina sp., No. 1415, Java (RouyerJ. 



Six specimens of this species have been examined of which three, 

 only, are matured. In all of these, the branches of the main append- 

 age have disappeared. The species is, hoAvever, very clearly dis- 

 tinguished by its long and slender habit, and could not be confused 

 with any known form. 



Rhachomyces orientalis nov. sp. 



Receptacle determinate, consisting of four superposed cells, followed 

 by two cells more or less obliquely associated side by side; the basal 

 cell narrow, rather short, distally broader and suffused with blackish 

 brown: the second, subbasal, more deeply suffused, broader than 

 long, subtriangular, distally pointed or obliquely separated from the 

 third cell, and bearing a single simple straight appressed short usually 

 four-celled primary appendage; the basal cell of which is broader, 

 deeply suffused and distinguished above by a broad V>lack slightly
