32 THAXTER. 



This species does not appear to be nearly allied to any described 

 form, and is clearly distinguished e&pecially by its dark appendages. 

 It seems to be decidedly rare. 



Rickia Stenotarsi nov. sp. 



Quite hyaline, or the perithecium tinged with blue; tapering more 

 or less sjTiimetrically to the base, and often slightly twisted below, so 

 that it is turned partly edge'^ise. Receptacle triseriate, the basal 

 cell usually strongly bent, with a small brown patch next the foot, 

 intruded between the two nearly equal cells above it, so as to separate 

 them more or less completely; the anterior series extending to slightly 

 below the middle of the perithecium; consisting of usually twelve 

 somewhat elongated and flattened cells, the three upper smaller, lying 

 beside the perithecium; all except the basal cell cutting off from one to 

 three cells obliquely superposed, or lying side by side, or somewhat 

 irregularly associated: posterior series similar to the anterior, con- 

 sisting of usually eleven cells, the distal much smaller, round, and 

 lying lower than the corresponding cell of the median series ; the long, 

 slightly tapering free base of the primary appendage diverging laterally 

 between them: median series consisting of eleven or twelve cells, the 

 three or four distal ones lying beside the basal third or less of the 

 perithecium; the basal cell but slightly intruded between the second 

 pair of marginal cells; the lower four or five cells subrectangular, 

 twice or somewhat more than twice as long as broad. Antheridia 

 hyaline, divergent, numerous, rather slender, often slightly cur\ed; 

 the neck not abruptly distinguished. Appendages hyaline, rather 

 slender, slightly tapering, the lower shorter, the upper, including the 

 primary appendage, much longer. Perithecium hyaline, or yellowish, 

 or blue; the blue color, when present, extending to the well defined 

 subtending stalk-cell or even lower; its posterior margin more than 

 half free; nearly erect, relatively long, distally asymmetrical owing 

 to a more or less distinct bend of the large long well distinguished tip, 

 which is more convex on its inner side ; the small narrow truncate or 

 rounded apex turning more or less abruptly upward. Spores about 

 40 X 4 M- Perithecia 80-120 X 28-35 m- Antheridia 22 X 4 m- 

 Appendages 22 X 46 X 4 /x. Total length to tip of perithecium 

 200-350 X 40-55 m-
