NEW INDO-MALAYAN LABOULBENIALES. 13 



whole forming a dense terminal group, the members usually much 

 more elongate than those which arise lower down: the two subbasal 

 and the lateral cells also giving rise to numerous secondary appendages, 

 subtended by small lateral basal cells, either closely associated to form 

 a continuous margin, or variable and irregularly distributed singly or 

 in groups; the lumen of these cells small, the walls very thick, the 

 single cells or groups slightly prominent beyond the margin, each 

 separated from the appendage by a large cup-like brownish l^lack 

 suffusion at the constricted septum: the appendages variably elon- 

 gated, unicellular, cylindrical, or irregularly somewhat inflated, or 

 often slightly tapering. Antheridia apparently few in numl)er, 

 becoming more or less free and irregularly developed. Perithecium 

 concolorous, one half free, and convex on the inner side; wholly free 

 and straight, or slightly concave externally, usually projecting out- 

 ward at a slight angle to the axis; relatively small in well developed 

 individuals; the walls thick; the tip not distinguished, truncate 

 conical or bluntly rounded. Perithecia 75-80 X 35-38 /i. Spores 

 46 X 4.5 M- Receptacle 150-625 X 46-85 fj.. Lateral appendages 

 30-80 X 5 m; terminal up to 300 X 8 /x. 



In various positions on Heterophaga jmncfulata Motsch. (det. 

 Champion); No. 2108 Peradeniya, Ceylon. 



As will be seen from the above description, this species is clearly 

 distinguished by the unusual character of its perithecium, the greatly 

 elongated cells of which separate often very numerous appendiculate 

 cells seriately arranged along their margins. The occasional occur- 

 rence of septation in these long cells appears to be a secondary phe- 

 nomenon. The antheridia have not been very satisfactorily made 

 out, but, as in some other instances, appear to become more or less 

 free in irregular groups. Although far more highly developed this 

 species remotely resembles Rickia Lispini in the character of the 

 cell-series which form the receptacle. 



Rickia Coptengalis nov. sp. 



Rather long and broad with blackish brown and yellowish brown 

 suffusions; the receptacle of about the same width throughout, except 

 where it becomes narrowed at the base; the basal cell narrower than 

 the somewhat rounded foot, hyaline and contrasting with the two 

 suffused, paired, and nearly triangular cells above it, between which its 

 bluntly rounded distal end is intruded. Above this pair of cells the
