Rickia elegans nov. sp. 



Basal cell hyaline; cells of median row small, rounded; those of 

 marginal rows horizontally elongated or their axes directed upward 

 somewhat obliquely, more than fifty cells in the posterior row, about 

 twenty -five in the anterior; the cells at maturity in all the rows be- 

 coming deeply suffused with rich blackish brown and quite indis- 

 tinguishable; all the cells of the marginal rows cutting ofiF small cells 

 which remain almost wholly hyaline and bear short appendages, 

 their cup like bases rich brown, the distal portion hyaline. Peri- 

 thecium wholly united on its inner side to the median row, the last 

 two or three free cells of which reach to the middle of the short stout 

 deeply suffused rather broad tip, which is bent rather abruptly out- 

 ward; the apex hyaline, or translucent; the body nearly straight, 

 about the same diameter throughout, rather narrow, rich brown, not 

 as deep as the tip, the outer margin somewhat irregular, continuous 

 with that of the receptacle below. The whole plant straight or 

 curved, tapering gradually from apex to base. Perithecium 65-85 X 

 20 AC. Appendages about 15X4^- Total length 200-220X35- 

 40 m. 



On legs and margin of body of Discopoma sp. Peradeniya, Ceylon, 

 No. 2110. 



This species is very closely allied to R. Berlesiana Paoli (Bac), 

 differing chiefly in its much more numerous cells, which are smaller 

 and differently arranged and the total suffusion of the receptacle. 

 In fully mature specimens, the perithecium is concolorous with the 

 receptacle, and not distinguishable from it. 



Rickia cristata nov. sp. 



Basal cell three times as long as broad, its upper half or less included 

 between the lower cells of the marginal rows. Posterior row crest- 

 like, the cells radially elongated, each separating several appendiculate 

 cells, the pointed bases of which are intruded between them nearly 

 to their bases, the appendiculate cells becoming so multiplied, where 

 the series curves over against the tip of the perithecium, that the 

 primary cells are obliterated ; the primary cells of this series about 

 eighteen, the appendiculate cells thirty-six to forty: the anterior 

 series extending slightly beyond the middle of the perithecium, the 

 base of which it incloses, consisting of three or four cells from which a 

 number of appendiculate cells are cut off, as in the posterior series.
