NEW INDO-MALAYAN L.\BOULBENIALES. 19 



receptacle even shorter than the perithecium, the marginal portion 

 beside the perithecium being more prominently developed, almost all 

 the cells here bearing appendages; the primary appendage projecting 

 forward against the tip of the perithecium, which is not othenyise 

 exactly like that of the type. 



Rickia nutans nov. sp. 



Receptacle colorless, slender, elongate, often branched, the axis 

 consisting of two rows of cells above the basal cell; the three-celled 

 primary appendage remaining above the third cell from the foot, the 

 double axis extending indeterminately beyond it, its distal cell small 

 and distinguished by a finally blackened septum, the other two cells 

 forming a stout basal portion which is wholly free, distinguished by a 

 constriction from the cell which bears it and broader toward its base. 

 The two cell-series, whether primaiy or secondary, otherwise without 

 appendages, except one to three which always subtend the perithecium 

 below its convex side: the axis terminations curved and slightly 

 broader as the perithecia are reached, about five flattened cells of one 

 of the cell-series forming a hyaline narrow contrasting margin, extend- 

 ing to the apex of the perithecium on its convex side; one to three of the 

 terminal cells of the other series larger, obliquely elongated laterally 

 and upward, the uppermost in oblique contact with the perithecium 

 for a short distance above its base. Perithecium continuing the 

 curvature of the axis which bears it, rich brown, contrasting, the tip 

 much darker, but not otherwise differentiated; two of the lip-cells 

 forming relatively long, stout, tapering, divergent, blunt appendages, 

 which are directed vertically or obliquely do^\^lward. Perithecia 

 58-66 X 20 /u, the apical appendages 15-16 ju. Total length 750 n 

 or less, the diameter about 12 jjl, just below the perithecium about 

 16 n. 



x\t the tip of the abdomen of large Passali. No. 2114a, Peradeniya, 

 Ceylon. 



This species is very clearly distinguished by its brown appendiculate 

 perithecium and nodding habit, which suggests the head and neck of a 

 flamingo. The third row of axis-cells is not developed as in more 

 typical species, and is represented by the single cell which subtends 

 the primary appendage near the base.
