42 THAXTER. 



more or less faintly suffused with dirty brownish ; the five or sLx distal 

 ones, lying beside the lower third of the perithecium, much smaller 

 and subequal : anterior series consisting of about twenty-five to twenty- 

 nine cells, those below the perithecium subequal, subtriangular, 

 hyaline or faintly and irregularly suffused inwardly with dirty yellow- 

 ish brown ; the six to eight distal cells evenly suffused with yellowish 

 brown; small, rounded; the upper somewhat smaller and extending to 

 about two thirds or three quarters of the total length of the perithe- 

 cium; all the cells, except two or three of the terminal ones, cutting 

 oft' one to three superposed cells, which bear copious appendages and 

 scanty antheridia: posterior series similar to the anterior, ending 

 beside the distal cell of the median series, the basal cell of the primary 

 appendage lying just above their terminations, in contact with the 

 perithecium, and not distinguished from the cells below, its distal cell 

 short, broad, subtriangular, free, diverging laterally. Antheridia very 

 scanty, usually only one or two on the anterior series, opposite the base 

 of the perithecium ; about as long as the hyaline, stout, rather irregu- 

 lar appendages, purplish; the neck more deeply colored, long, slender, 

 and abruptly distinguished. Perithecia usually esect and straight, 

 the insertion slightly lateral, rich purplish brown, the surface more or 

 less distinctly mottled; one half or more of the posterior, and one 

 fourth of the anterior margin free; the enclosed portion narrower; 

 the tip broadly conical, the margins slightly convex, short, abruptly 

 distinguished, subtended by a paler or almost hyaline line; the apex 

 flat and broad, hyaline, the lip-cells projecting slightly. Spore about 

 50 X 5 M- Perithecia 80-100 X 27-30 m- Antheridia 16 X 4 m- Ap- 

 pendages 10-20 X 2 ^i. Total length to tip of perithecium 310-425 fx. 



On Episcapha antennata, Nos. 2391 and 2392, Mindanao, Philippines. 



Numerous individuals have been examined of this large and hand- 

 some species which is most nearly related to R. Coptengalis, from which 

 it differs in the more highly developed receptacle, the relation of its 

 perithecium to the latter, and the form of its tip, as well as in the very 

 scantily developed antheridia. 



Rickia Eumorphi nov. sp. 



Straight or slightly curved, hyaline and rich brown, contrasting; 

 large, long, broader in the region of the perithecium, below which it 

 tapers very gradually, or hardly at all, to the basal cells of the marginal 

 series. Receptacle indeterminate, triseriate; the basal cell hyaline.
