32 THAXTER. 



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

 form, and is clearly distinguished especially 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 symmetrically to the base, and often slightly twisted below, so 

 that it is turned partly edgewise. 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 curved; 

 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 ju- Antheridia 22 X 4 m- 

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

 200-350 X 40-55 y..
