CHITONOMYCES AND RICKIA. 49 



Rickia Sarawakensis nov. sp. 



Asymmetrical. Receptacle hyaline, triseriate, both the foot and 

 the basal cell relatively very large, the latter geniculate below, distally 

 broader and rounded: anterior series consisting of two superposed 

 cells, the upper smaller and separated from the base of the perithecium 

 by a small well defined stalk-cell: both cutting off two cells distally 

 and externally, which bear antheridia or appendages of the normal 

 type: posterior series consisting of four cells, which may be subequal; 

 all cutting off two cells which bear antheridia or appendages; the 

 uppermost corresponding to the lower cell of the base of the primary 

 appendage, larger, almost wholly free beside the base of the perithe- 

 cium, cutting off an appendiculate cell externally and followed dis- 

 tally by the upper cell which is bent inward toward the perithecium: 

 median series consisting of two superposed cells, the lower larger, but 

 slightly intruded between the second pair of marginal cells; the upper 

 very small, lying just beside the base of the ascigerus cavity. Peri- 

 thecium wholly free, its insertion slightly oblique, rather short and 

 stout, rosy brown, usually subsigmoid; the tip, which is not at all 

 distinguished, bent outward slightly; the small hyaline truncate apex 

 bent abruptly upward or inward. Spores about 28 X 2.8 /x. Peri- 

 thecia 45 X 19 fx. Appendages 10 X 4 /x. Antheridia 10 X 3.5 fx. 

 Total length to tip of perithecium 95 X 10-12 fx. 



On elytra of Phalacrus (?) sp., Sarawak, Borneo, No. 2371. 



A small and simple species clearly distinguished by its free rosy 

 brown perithecium. It is one of the few species in which the lower 

 cell of the base of the primary appendage cuts off an appendiculate 

 cell. The body of the receptacle consists of an unusually small num- 

 ber of cells, for a species of this normal type, which do not in general 

 differ greatly in size, being mostly somewhat longer than broad and 

 rather irregularly rounded in outline. 



Rickia Parasiti nov. sp. 



Hyaline, relatively long and narrow in general habit. Receptacle 

 triseriate, the basal cell relatively long and slender, but slightly broader 

 at the apex which is only slightly if at all intruded between the cells 

 above it : anterior series consisting of three, or usually four, superposed 

 cells; the lowest larger, twice as long as broad; the others successively
