CHITONOMYCES AND RICKIA. 43 



abruptly narrower and intruded somewhat between the two nearly 

 opaque cells above it, the deep suffusion of which may extend down- 

 ward beside its extremity in hooked prolongations: anterior series 

 wholly or partly involved by the opacity which makes the structure 

 of the median region quite indistinguishable, the distal cells beside 

 the perithecium usually hyaline or translucent; consisting of from 

 thirty-four to forty-eight similar cells, and extending to, or somewhat 

 above, the base of the perithecial tip; all except the small terminal 

 one cutting off from one to usually not more than three small hyaline 

 cells, bearing antheridia or appendages: posterior series similar to the 

 anterior and consisting of about the same number of cells, terminating 

 somewhat lower down than the anterior; its distal cell lying beside 

 that of the median series, the two bearing distally between them the 

 free relatively long and narrow base of the primary appendage, the 

 somewhat larger lower cell of which is separated from the upper by a 

 slightly oblique septum: median series wholly opaque and indis- 

 tinguishable, except four or five of its distal cells; the three or four 

 terminal ones being hyaline. Antheridia numerous, conspicuous, 

 the cylindrical, purplish brown, usually slightly curved necks often 

 longer than the slightly inflated venter. Appendages often shorter, 

 rarely longer, than the antheridia, hyaline, subcylindrical. Perithe- 

 cia rather long and narrow, sometimes slightly tilted, the basal portion 

 suffused with purplish brown to somewhat above the middle, deeper 

 on the posterior side, the distal portion tapering slightly and sub- 

 symmetrically to the coarse blunt apex; its lower half, or less, abruptly 

 hyaline or nearly so; its upper half or more abruptly and deeply 

 suffused, the suffusion extending lower than the short broad tip proper, 

 which is not distinguished except by its lateral deeper suffusion; a 

 rounded translucent brownish area below and including the median 

 pore. Spores about 40 X 3.6 fx. Perithecia 90-100 X 20-24 fx. 

 Antheridia 20 X 4 /x. Appendages 80-20 X 4 ^u- Total length to 

 tip of perithecium 230-400 X 40-55 fx. 



On Eumorphus cyanescens Gerst., No. 2390, Mindanao, Philippines. 



A fine and very striking species, most nearly allied to R. Coptengalis 

 and R. Episcaphae, and resembling R. Berlesiana in its axial suffusion, 

 which is much more extensive than in this species.
