CHITONOMYCES AND RICKIA. 41 



is shorter broader and more deeply suffused; the group forming a 

 straight jointed axis, somewhat constricted and darker at the septa; 

 the cells beside the peritheciuni hardly distinguishable from it in the 

 general suffusion of this region, the distal cell lying free beyond the 

 base of the primary appendage, but not reaching higher than the base 

 of the perithecial tip. Appendages mostly ovoid, shorter than the 

 numerous somewhat divergent, hyaline, rather stout antheridia; the 

 well distinguished, stout, purplish necks of which, are usually curved 

 slightly outward. Perithecia nearly symmetrical, not quite median, 

 erect or very slightly tilted, becoming deeply suffused with reddish 

 brown; the margins nearly straight, hardly distinguished from the 

 adjacent marginal cells; the tip well distinguished, very short and 

 broad, distally blackened below the broad flat contrasting hyaline 

 apex. Spores about 28 X 3 /x. Perithecia 60-66 X 12-18 n. Ap- 

 pendages 54 X 3.6 fj.. Antheridia 11 X 4 /x. Total length to tip of 

 peritheciuni 145-160 X 32-36 /x. 



On the elytra of Ancylopus bisignatus Gerst, No. 2562, Kamerun. 



A species very readily distinguished by the peculiar appearance of 

 the portion of the receptacle lying below the peritheciuni, where the 

 median cell-series forms a clearly defined suffused bamboo-like axis, 

 to the ends of the segments of which the suffused or blackened cells of 

 the marginal series are sometimes, though not always, adjusted in 

 almost perfectly symmetrical pairs, ha\ing the appearance of broad 

 dark appendages projecting outward from them and ending in a more 

 deeply blackened tooth-like termination which subtends the slight 

 convexity on which the appendiculate cell rests. Like other suffused 

 forms, this species recalls in its general appearance that of some forms 

 of Rhachonii/ces. 



Rickia Episcaphae nov. sp. 



Receptacle triseriate, symmetrical l)elow the peritheciuni and of 

 equal width almost to the basal pair of marginal cells, whence it tapers 

 rather abruptly to the foot; the basal cell hyaline, somewhat broader 

 distally, and slightly intruded between the two cells above it; which 

 are similar, sjyTnmetrically paired, and subtriangular, more or less 

 completely and deeply suffused with reddish brown, the suffusion often 

 involving to some extent the cells immediately above: median series 

 consisting of from twelve to sixteen cells; the fourteen to sixteen lying 

 below the peritheciuni very regular in form and size, somewhat longer 

 than broad, subrectangular with rounded angles, their walls, especially.
