CHITOXOMYCES AXD RICKIA. 33 



This well defined species is perfectly hyaline, except that in a 

 majority of the very numerous individuals examined, the perithecia, 

 and sometimes certain cells below it, are tinged with rather bright 

 blue, as if stained with haematoxylin. That this color is not acci- 

 dental seems to be indicated by the fact that some perithecia from the 

 same source are quite hyaline, and that no other parts of any individ- 

 uals are thus colored: yet it is not certain that this very unusual color 

 may not have been due to the accidental presence of some staining 

 material in the containing bottle. 



Rickia latior nov. sp. 



Quite hyaline, short and broad. Receptacle triseriate, the basal 

 cell brown, its Inroad blunt upper half hyaline and completely separat- 

 ing the first pair of marginal cells: anterior series reaching to about 

 the middle of the perithecium, consisting of ten obliquely superposed 

 cells, all of which, except the basal, cut off from one to four cells, 

 unusually prominent with free ends; which bear appendages, or copi- 

 ous antheridia, arising side by side in a more or less regular trans- 

 verse series: posterior series consisting of eight cells, similar to the 

 anterior, and terminating in a very small cell; which bears the large, 

 long, slightly tapering base of the primary appendage: median series 

 consisting of from six to eight cells; the lower three or four obliquely 

 superposed; the upper three or four lying beside the lower two fifths 

 or less of the perithecium, the uppermost opposite the last cell of the 

 posterior series. Antheridia very numerous, long, slender, tapering, 

 slightly curved, hyaline. Appendages variable in length, the upper- 

 most usually longer; hyaline, tapering. Perithecia very thick-walled, 

 becoming pale straw-yellow, asymmetrical, more or less strongly and 

 abruptly curved inward, so that the apex may project laterally beyond 

 the posterior margin of the receptacle; the tip very abruptly dis- 

 tinguished, especially along its anterior margin; the apex well dis- 

 tinguished, longer than broad, distally truncate, or obliquely rounded. 

 Spores 38 X 3.8 m- Perithecia 80-90 X 27-30 m- Antheridia 9 X 

 3.6 /i. Appendages 18-60 X 3.6 /j.. Total length to tip of perithe- 

 cium 48-70 n. 



On the elytra of Stenotarsus Guineensis Gerst., No. 2363, Kamerun. 



This form is perhaps too closely allied to R. Stenotarsi which occurs 

 on the elytra of the same host. It differs in its short broad habit, 

 obliquely superposed axial cells, simpler structure, more numerous
