CHITOXOMYCES AND RICKIA. 45 



Rickia pallescens nov. sp. 



Erect, straight, somewhat soiled or stained with brownish above. 

 Receptacle triseriate, basal cell rather large, distally slightly broader 

 and not intruded between the basal cells of the marginal series; which 

 are similar to the basal cell, or the posterior slightly longer, and sub- 

 symmetrically paired as are the two shorter broader marginal cells 

 immediately above them: anterior series consisting of usually twelve 

 superposed cells becoming smaller distally, and in contact with some- 

 what more than half the anterior margin of the perithecium; all the 

 cells, except the lowest cutting off, the subbasal one, the rest several 

 small appendiculate cells distally and externally; which, in the latter 

 case, lie side by side; those of the mid-region bearing for the most 

 part antheridia, the rest mostly minute appendages: posterior series 

 similar to the anterior and extending nearly as far upward, terminating 

 in the primary appendage which, with its base, is hardly distinguish- 

 able from the secondary ones associated with it: median series con- 

 sisting of eight or nine cells, the three lowest larger, the rest becoming 

 gradually smaller; the distal or subdistal usually cutting off an ap- 

 pendiculate cell or bearing an appendage directly; the series not 

 extending cjuite as far upward as the other two. Antheridia numer- 

 ous and typical, rather large, appressed or somewhat divergent, 

 asymmetrical; the necks somewhat tapering and tinged with dirty 

 purplish brown, more or less distinctly curved outward. Perithecium 

 erect, straight, deeply suffused with dirty olive brown; rather long and 

 narrow, free on both sides from just below the tip; which is abruptly 

 distinguished, straight and stout, the apex slightly distinguished, 

 subhyaline, broad, flat, symmetrically rounded. Spores about 30 X 

 2.8 At. Perithecia 68-75 X 18-22 m- Antheridia 15 X 4 m- Total 

 length to tip of perithecium 150-200 X 35-45 //. 



On the legs of a small species of Coproporus, No. 2543, Manila, 

 P. I. 



Closely allied to R. nigrcscens of which it may prove only a variety. 

 It differs in its nearly hyaline receptacle and pale perithecium which 

 is more completely surrounded by the former: the tip and apex 

 broader and differently shaped. 



Rickia Circopis nov. sp. 



Straight, erect, slightly asymmetrical. Receptacle triseriate, hya- 

 line; basal cell rather short, distallv broader, hardlv intruded be-
